At the fully closed position of the window glass W (FIG. 1), the upper edge of the window glass W enters the glass run storage portion 23 of the upper sash 11. The glass run comes into close contact with the vehicle outer side surface W1, the vehicle interior side surface W2, and the edge surface W3 of the window glass W that has entered the glass run storage portion 23, and becomes a watertight state that prevents intrusion of raindrops and the like into the vehicle interior and the window. The upper edge of the glass W is elastically held by the glass run.

As shown in FIG. 9, the upper sash 11 is further formed with a weatherstrip holding portion 24 on the outer peripheral side opposite to the glass run storage portion 23. The weatherstrip holder 24 holds a weatherstrip (not shown in FIG. 9) made of an elastic material. The weather strip held by the weather strip holding portion 24 is continuous with the weather strip 38 (FIGS. 5 and 6) held by the upright pillar sash 12 described later.

As shown in FIGS. 2 and 3, the upright pillar sash 12 is configured by combining an inner sash 30 that is a long member and a guide rail (guide member) 40. The material of the inner sash 30 and the guide rail 40 may be made of metal such as iron and aluminum, or may be made of non-metal such as synthetic resin. In this embodiment, the inner sash 30 is made of iron or aluminum, and the guide rail 40 is made of aluminum. The window glass W has a curved shape that is convex toward the outside of the vehicle. Corresponding to the curved shape of the window glass W, the upright pillar sash 12 also has a curved shape that is convex toward the outside of the vehicle. The structure of the upright pillar sash 12 will be described mainly with reference to FIGS. 5 and 6.

The inner sash 30 has a frame portion 31 located inside the vehicle, a design portion 32 located outside the vehicle, and a step portion 33 connecting the frame portion 31 and the design portion 32. The frame portion 31 is a portion corresponding to the frame portion 20 in the upper sash 11. More specifically, the frame portion 31 includes a vehicle inner side wall 31a located inside the vehicle, an inner peripheral side wall 31b extending from the inner peripheral side end of the vehicle inner side wall 31a to the vehicle outer side, and an outer peripheral side end of the vehicle inner side wall 31a. It has an outer peripheral side wall 31c extending to the outside of the vehicle. The inner peripheral side wall 31b and the outer peripheral side wall 31c are spaced apart from each other with increasing distance from the vehicle inner side wall 31a.

Unlike the frame portion 20 (see FIG. 9) of the upper sash 11 which has a closed cross-sectional shape, the inner sash 30 of the upright pillar sash 12 connects the outer side end portions of the inner peripheral side wall 31b and the outer peripheral side wall 31c in the frame portion 31. It has a bag-like cross-sectional shape that is opened toward the outside of the vehicle without doing so.

The step portion 33 of the inner sash 30 includes an outer peripheral extension portion 33a extending from the vehicle outer side end portion of the outer peripheral side wall 31c toward the outer peripheral side, and a vehicle outer extension portion extending from the outer peripheral side end portion of the outer peripheral side extension portion 33a to the vehicle outer side. 33b. The design portion 32 extends toward the outer peripheral side from the end portion on the vehicle outer side of the vehicle exterior extending portion 33b.

The guide rail 40 is arranged so as to fit inside the open portion on the vehicle outer side of the frame portion 31 and the step portion 33 of the inner sash 30. More specifically, the guide rail 40 includes a vehicle inner side wall 41 located inside the vehicle, an inner peripheral side wall 42 extending from the inner peripheral side end of the vehicle inner side wall 41 to the vehicle outer side, and an outer peripheral side end of the vehicle inner side wall 41. It has an outer peripheral side wall 43 extending to the outside of the vehicle, and an outer peripheral extending portion 44 extending from the end of the outer peripheral side wall 43 on the outside of the vehicle toward the outer peripheral side. A bent portion 45 that projects toward the outer peripheral side is provided at an end portion on the vehicle outer side of the inner peripheral side wall 42.

In the guide rail 40, an inner peripheral side wall 42 and an outer peripheral side wall 43 that are spaced apart from each other in the inner and outer peripheral directions, and a vehicle inner side wall 41 that connects them form a concave portion that is open toward the vehicle outer side. It is a space S. The pair of facing surfaces (the inner surface facing the guide space S) of the inner peripheral side wall 42 and the outer peripheral side wall 43 are substantially parallel to each other and extend in the up-down direction while keeping a constant interval in the inner-outer peripheral direction. The inner peripheral side wall 42 and the outer peripheral side wall 43 are fitted inside the inner peripheral side wall 31b and the outer peripheral side wall 31c of the frame portion 31 of the inner sash 30, respectively. Therefore, the inner peripheral side wall 42 and the outer peripheral side wall 43 respectively become thicker as they move away from the vehicle interior side wall 41 toward the vehicle exterior side. The inner wall 42 and the outer wall 43 have the largest wall thickness, which is the end surface facing the vehicle exterior. The end surface of the inner peripheral side wall 42 and the end surface of the outer peripheral side wall 43 are substantially flush with each other across the opening of the guide space S.

The bent portion 45 projects from the end portion on the vehicle outer side where the wall thickness of the inner peripheral side wall 42 is maximum, in a direction (outer peripheral side) in which the wall thickness of the inner peripheral side wall 42 is further increased, and The outside of the car is partially blocked. That is, due to the bent portion 45, the opening width of the guide space S in the inner and outer peripheral directions is narrower than the width inside the guide space S.

By fitting the inner peripheral side wall 42 and the outer peripheral side wall 43 to the inner peripheral side wall 31b and the outer peripheral side wall 31c of the frame portion 31, the relative positions of the inner sash 30 and the guide rail 40 in the inner and outer peripheral directions and the vehicle interior and exterior directions are determined. .. At this time, the outer peripheral extension portion 33a of the stepped portion 33 of the inner sash 30 and the outer peripheral extension portion 44 of the guide rail 40 overlap in the vehicle interior and exterior directions. A through hole 33c is formed in the outer peripheral extension portion 33a, and a through hole 44a is formed in the outer peripheral extension portion 44. When the inner sash 30 and the guide rail 40 have a predetermined vertical positional relationship, the through hole 33c and the through hole 44a communicate with each other in the vehicle interior and exterior directions.

In this state, insert the shaft portion of the bolt 17 into the through hole 33c and the through hole 44a from the inside of the vehicle. The shaft portion of the bolt 17 protruding into the step portion 33 is screwed into the nut 18. The inner sash 30 and the guide rail 40 are fixed by applying a predetermined tightening torque with the head of the bolt 17 in contact with the outer peripheral extension 33a. As shown in FIG. 3, fastening and fixing with the bolt 17 and the nut 18 is performed at a plurality of positions in the longitudinal direction of the inner sash 30 and the guide rail 40.

An inner garnish 34 that covers the frame portion 31 of the inner sash 30 from the inside of the vehicle, and an outer garnish 35 that covers the design portion 32 and the step portion 33 from the outside of the vehicle. The inner garnish 34 and the outer garnish 35 are long members extending in the longitudinal direction of the upright sash 12, and are made of synthetic resin or metal. The inner garnish 34 constitutes the exterior of the upright pillar sash 12 on the inside of the vehicle, and the outer garnish 35 constitutes the exterior of the upright pillar sash 12 on the outside of the vehicle.

There is a space between the outer garnish 35 and the step portion 33, and the screwed portion of the bolt 17 and the nut 18 is located in this space. Therefore, by attaching the outer garnish 35, the fastening portion between the inner sash 30 and the guide rail 40 cannot be seen from the outside of the vehicle. The inner garnish 34 and the outer garnish 35 are fixed to the inner sash 30 by predetermined fixing means (adhesion or the like).

An elastic cover 36 and an elastic cover 37 are attached to the guide rail 40 at a position on the inner peripheral side of the outer garnish 35. Each of the elastic covers 36 and 37 is made of a non-water-permeable elastic material (for example, rubber) and is a long member extending in the longitudinal direction of the upright pillar sash 12. 5 and 6 show the shapes of the elastic covers 36 and 37 in the initial state (free state) where no external force is applied.

A seating surface is provided on the end surface of the guide rail 40 facing the vehicle outer side, and

elastic covers

36, 37 are supported on the vehicle outer side surface of the seating surface. The seat surface is divided into an inner peripheral side seat surface 46 and an outer peripheral side seat surface 47 with the opening of the guide space S interposed therebetween. The inner peripheral side bearing surface 46 is supported by the end surface of the inner peripheral side wall 42. The outer peripheral side bearing surface 47 is supported from the end surface of the outer peripheral side wall 43 to the outer peripheral extended portion 44. The elastic cover 36 located on the inner peripheral side is supported on the inner peripheral side bearing surface 46, and the elastic cover 37 located on the outer peripheral side is supported on the outer peripheral side bearing surface 47. The elastic cover 36 and the elastic cover 37 are respectively fixed to the inner peripheral side bearing surface 46 and the outer peripheral side bearing surface 47 by a predetermined fixing means (adhesion or the like).

The elastic cover 36 has a hollow portion 36a having a hollow inside and a cantilevered lip portion 36b extending from the hollow portion 36a to the outer peripheral side, and the hollow portion 36a is supported by the inner peripheral side bearing surface 46. There is. A part of the hollow portion 36a extends in a cantilever manner toward the inner peripheral side to cover the vehicle outer side end portion of the inner garnish 34, and prevents the end portion of the inner peripheral side wall 31b of the inner sash 30 from being exposed. ..

The elastic cover 37 includes a base portion 37a supported by the outer peripheral side bearing surface 47, a plate-shaped portion 37b protruding from the base portion 37a to the inside of the vehicle, and a cantilever shape protruding from the vicinity of the tip of the plate-shaped portion 37b to the inner peripheral side. A first lip portion 37c, a cantilever-shaped second lip portion 37d protruding from the vicinity of the inner peripheral side end portion of the base portion 37a toward the vehicle outer side and the inner peripheral side, and a holding portion 37e located on the outer peripheral side of the plate portion 37b. And have.

The lip portion 36b of the elastic cover 36 and the second lip portion 37d of the elastic cover 37 extend in directions toward each other and cover the outer side of the vehicle in the guide space S. The first lip portion 37c of the elastic cover 37 is located on the vehicle outer side than the second lip portion 37d. The outer garnish 35 has a bent portion 35a formed by bending an end portion on the inner peripheral side toward the inside of the vehicle. The bent portion 35a is fitted between the plate-like portion 37b and the pressing portion 37e to stably hold the elastic cover 37.

The upright sash 12 of the present embodiment has a so-called flash surface structure in which the vehicle outer surface of the outer garnish 35 is located at substantially the same position as the vehicle outer surface W1 of the window glass W in the vehicle interior and exterior directions. The elastic covers 36 and 37 contribute to waterproofing around the window glass W and vibration suppression in the flash surface structure.

The first lip portion 37c of the elastic cover 37 is located at a position facing the rear edge surface W3 of the window glass W in the inner and outer peripheral directions. The first lip portion 37c is pushed outward by the edge surface W3 and elastically deforms. The plate-like portion 37b receives the pressing force applied to the first lip portion 37c, and the plate-like portion 37b abuts the bent portion 35a of the outer garnish 35 to restrict the movement toward the outer peripheral side. Further, since the plate portion 37b and the pressing portion 37e are fitted in the bent portion 35a, the stability of the elastic cover 37 is high. Therefore, the first lip portion 37c comes into close contact with the edge surface W3 with a predetermined reaction force to seal the space between the window glass W and the outer garnish 35 in a watertight manner and suppress the vibration of the window glass W.

The hollow portion 36a of the elastic cover 36 is located between the vehicle interior side surface W2 of the window glass W and the guide rail 40 (inner circumferential side bearing surface 46) in the vehicle interior and exterior direction. The protruding portion of the hollow portion 36a toward the vehicle exterior is pressed by the vehicle interior side surface W2 of the window glass W, and the hollow portion 36a is compressed and deformed in the vehicle interior and exterior directions. As a result, the elastic cover 36 closes the space between the vehicle interior side surface W2 and the guide rail 40 in a watertight manner and suppresses the vibration of the window glass W. In addition to sealing the edge surface W3 of the window glass W with the first lip portion 37c and the hollow portion 36a with respect to the vehicle interior side surface W2 of the window glass W, the watertightness between the window glass W and the upright sash 12 is improved. Further improve.

In particular, in the door 10 of the present embodiment, the constituent elements of the window regulator 19 are incorporated in the upright pillar sash 12 as described later. Therefore, highly effective waterproofing between the window glass W and the upright pillar sash 12 by the elastic covers 36 and 37 is highly effective.

Although details will be described later, the guide space S of the guide rail 40 is a portion that slidably supports the slider shoes 52, 53 attached to the window glass W. Then, the position of the window glass W in the inner and outer peripheral directions is determined by the inner peripheral side wall 42 and the outer peripheral side wall 43 that form the guide space S of the guide rail 40, and the window in the vehicle interior and exterior direction is defined by the vehicle interior side wall 41 and the bent portion 45. The position of the glass W is determined. An inner peripheral side bearing surface 46 and an outer peripheral side bearing surface 47 that support the elastic covers 36 and 37 are provided on the guide rail 40. That is, both the window glass W and the elastic covers 36 and 37 are positioned with reference to the guide rail 40. As a result, the positional relationship between the window glass W and the elastic covers 36 and 37 is stabilized (hard to be dispersed). Since the elastic covers 36, 37 function as a sealing member by being pressed by the window glass W, when the positional relationship between the window glass W and the elastic covers 36, 37 is stable, the elastic covers 36, 37 are not attached to the respective portions of the window glass W and the upright sash 12. The adhesiveness of the elastic covers 36 and 37 is stable, and a high degree of watertightness due to the elastic covers 36 and 37 can be secured.

Further, as will be described later, since the elastic covers 36 and 37 bring the lip portion 36b and the second lip portion 37d into contact with the slider base 51, the positional relationship between the window glass W and the elastic covers 36 and 37 is stable. If so, fluctuations in load on the slider base 51 are suppressed, and sliding performance of the slider base 51 on the guide rail 40 is improved.

The outer garnish 35 and the elastic cover 37 are located on the outermost side of the upright sash 12 and form the outer surface of the door 10 together with the window glass W. In the elastic cover 37, the base end side of the first lip portion 37c (the side connected to the plate-like portion 37b) is substantially flush with the vehicle outer surface W1 of the window glass W and the vehicle outer surface of the outer garnish 35. Therefore, the elastic cover 37 has an excellent waterproof performance, and can form the appearance of the flash surface structure together with the window glass W and the outer garnish 35, and improve the appearance quality.

Further, on the inner peripheral side of the outer garnish 35, the entire elastic cover 36 and the second lip portion 37d of the elastic cover 37 are located inside the window glass W, and the internal structure of the upright sash 12 is almost visible. Covered without. Therefore, an excellent aesthetic appearance can be obtained even in a region where the window glass W and the upright sash 12 overlap in the vehicle interior and exterior directions.

Further, a weather strip 38 is attached to the vertical pillar sash 12. The weather strip 38 is made of a non-water-permeable elastic material (for example, rubber). A seat surface 39 facing the outer peripheral side is provided on the outer peripheral side wall 31c of the inner sash 30, and the leg portions 38a of the weather strip 38 are fixed to the seat surface 39. Since the weather strip 38 covers a part of the inner garnish 34, the step between the outer peripheral side wall 31c of the inner sash 30 and the inner garnish 34 becomes invisible from the inside of the vehicle.

Further, the weather strip 38 covers the outer peripheral extension portion 33a of the step portion 33 from the inside of the vehicle. The area covered by the weather strip 38 also includes the head of the bolt 17. Therefore, by attaching the weather strip 38, the fastening portion between the inner sash 30 and the guide rail 40 becomes invisible from the inside of the vehicle.

The weather strip 38 has a hollow elastic contact portion 38b protruding from the leg portion 38a. When the door 10 is closed with respect to the vehicle body, the elastic contact portion 38b comes into contact with the body pillar P of the vehicle body extending along the door opening and elastically deforms, so that a watertight seal is formed between the vehicle body and the door 10 (standing pillar sash 12). Close to.

The door 10 is equipped with a window regulator 19 that drives the window glass W up and down. As shown in FIGS. 2 and 3, the window regulator 19 supports and guides the window assembly 50 by the guide rail 40 so as to be movable in the vertical direction, and transmits the driving force of the drive unit (driving means) 60 to the window assembly 50. Then, the window glass W is moved up and down. The components of the window regulator 19 are incorporated in the upright pillar sash 12. The structure for driving the glass up and down, including the window regulator 19, will be described below.

As shown in FIG. 4, the window assembly 50 includes a slider base (slider, base member) 51, a pair of slider shoes (slider, shoe members) 52, 53, a rack 54, a slide guide 55, and a window glass. It is assembled to W.

Edge of window glass W is longer than the front edge. The slider base 51 is a long member that extends in the vertical direction, and has a length that extends along substantially the entire rear edge of the window glass W. The slider base 51 may be made of metal or non-metal such as synthetic resin. The slider base 51 has a glass fixing portion (inner surface fixing portion) 51a located on the outside of the vehicle and a connecting portion 51b protruding from the glass fixing portion 51a toward the inside of the vehicle, and has a substantially T-shaped cross section perpendicular to the longitudinal direction. It is in the shape of.

The glass fixing part 51a is a plate-shaped part whose front and back surfaces (side surfaces) face inward and outward of the vehicle. The outer surface of the glass fixing portion 51a is fixed to the attachment region G1 (FIG. 4) of the inner surface W2 of the window glass W by adhesion or the like. As shown in FIGS. 5 and 6, the glass fixing portion 51a extends to the outer peripheral side of the fixing portion to the mounting region G1, and the outer peripheral end of the glass fixing portion 51a has an edge surface W3 of the window glass W. It is located on the outer peripheral side.

As shown in FIGS. 4 and 10, a lower end receiving portion (edge receiving portion) 51c is provided at the lower end of the glass fixing portion 51a. The lower end receiving portion 51c is a flat plate-shaped portion that projects from the glass fixing portion 51a to the outside of the vehicle. The lower end portion of the glass fixing portion 51a is formed with a widening portion 51g that gradually increases in width in the inner and outer peripheral directions (widens) as it goes downward, and a lower end receiving portion 51c is continuous with the widening portion 51g. Formed (see FIG. 4). The protruding amount of the lower end receiving portion 51c from the glass fixing portion 51a to the outside of the vehicle is equal to or larger than the thickness of the window glass W. When the slider base 51 is attached to the window glass W, the position of the slider base 51 is determined so that the lower end of the window glass W is supported by the lower end receiving portion 51c (see FIG. 10). The edge surface W3 of the window glass W has a rounded cross-sectional shape, and the edge surface W3 on the lower end side which is the end in the opening operation direction of the window glass W contacts the lower end receiving portion 51c in a linear region. To do.

When attaching the slider base 51 to the window glass W, the lower end receiving portion 51c is brought into contact with the lower end of the window glass W, and then the glass fixing portion 51a is bonded to the vehicle interior side surface W2. As a result, the lower end receiving portion 51c serves as a position reference in the vertical direction, and the slider base 51 can be fixed to the window glass W with high accuracy.

The force that relatively moves the window glass W and the slider base 51 in the vertical direction acts as a shear load in the vertical direction between the vehicle interior side surface W2 (mounting region G1) and the glass fixing portion 51a. By receiving the lower end of the window glass W by the lower end receiving portion 51c provided on the slider base 51, the window glass W and the slider base 51 can be fixed to each other with high strength. It is possible to surely prevent the positional deviation and separation of the 51.

The connecting portion 51b is a plate-like portion that protrudes from the surface of the glass fixing portion 51a on the inner side of the vehicle and has both side surfaces facing inward and outward. A part of each of the upper end side and the lower end side of the connection portion 51b forms a

shoe support portion

51d, 51e by increasing an amount of protrusion to the inside of the vehicle. The slider shoe 52 is attached to the shoe support portion 51d on the upper end side, and the slider shoe 53 is attached to the shoe support portion 51e on the lower end side. Each of the

shoe support portions

51d and 51e has an L-shaped cross-sectional shape in which the vehicle-inside end portion of the connection portion 51b is bent to the outer peripheral side, and the slider shoes 52 and 53 are fitted into the L-shaped portions. (See FIGS. 4 and 6).

The slider shoes 52 and 53 respectively have sliding

base portions

52a and 53a having a rectangular cross-sectional shape that fits within the guide space S of the guide rail 40. From the sliding

bases

52a and 53a, cantilever-shaped first

elastic contact portions

52b and 53b and cantilever-shaped second

elastic contact portions

52d and 53d respectively project. Further,

stopper portions

52c and 53c project from the sliding

base portions

52a and 53a in the longitudinal direction of the slider base 51. Each of the slider shoes 52 and 53 is formed of a synthetic resin or the like having a hardness lower than that of the material forming the guide rail 40 in order to realize smooth movement while preventing abnormal noise and vibration.

The slider shoe 52 and the slider shoe 53 are members having the same structure, and are assembled to the slider base 51 in a vertically inverted relationship. As shown in FIG. 7, the slider shoe 52 on the upper end side is assembled with the stopper portion 52c facing downward. The stopper portion 52c extends downward along the inner peripheral surface of the connecting portion 51b of the slider base 51. The slider shoe 53 on the lower end side is assembled with the stopper portion 53c facing upward. The stopper portion 53c extends upward along the outer peripheral surface of the connecting portion 51b of the slider base 51.

When the slider shoe 52 is assembled to the slider base 51, the first elastic contact portion 52b projects toward the inside of the vehicle with respect to the sliding base portion 52a, and the second elastic contact portion 52d (see FIG. 8) surrounds the sliding base portion 52a. Project to the side. When the slider shoe 53 is assembled to the slider base 51, the first elastic contact portion 53b projects inward from the sliding base portion 53a, and the second elastic contact portion 53d projects inward from the sliding base portion 52a. .

By inserting the fixing screw 56 (FIG. 4) into the holes formed in the sliding

bases

52a and 53a and screwing the fixing screw 56 into the screw holes provided in the

shoe support parts

51d and 51e to tighten the slider shoe. 52 and 53 are fixed to the slider base 51, respectively.

As shown in FIG. 4, a rack 54 is further attached to the slider base 51. The rack 54 is a long member extending in the vertical direction, and has a length of the slider base 51 excluding a part of upper and lower ends to which the slider shoe 52 and the slider shoe 53 are attached.

As shown in FIGS. 4 and 5, the rack 54 has a main body portion 54a and a plate-shaped mounting portion 54b protruding from the main body portion 54a to the outside of the vehicle. A mounting hole 54c (FIG. 5) is formed in the mounting portion 54b so as to penetrate in the plate thickness direction. A plurality of mounting portions 54b and mounting holes 54c are provided at different positions in the longitudinal direction of the rack 54.

The rack 54 is attached to the slider base 51 with the attachment portion 54b abutting on the outer peripheral surface of the connection portion 51b. A plurality of screw holes 51f corresponding to the mounting holes 54c are formed in the connecting portion 51b, and a fixing screw 57 (FIGS. 4 and 5) is screwed into each screw hole 51f through each mounting hole 54c and tightened. Then, the rack 54 is fixed to the slider base 51. A portion of the main body portion 54a that faces the vehicle outer side is a recess into which the vehicle inner side end of the connection portion 51b is fitted (see FIG. 5), and the rack 54 can be firmly fixed to the slider base 51. it can.

The teeth 54d are formed at equal intervals in the longitudinal direction on the surface of the main body 54a of the rack 54 that faces the inner peripheral side when attached to the slider base 51 (see FIGS. 4 and 7). The tooth 54d is formed by partially recessing the main body portion 54a, and the vehicle outer side and the vehicle inner side of the tooth 54d are closed by the

side wall portions

54g and 54h forming the body portion 54a. By providing the

side walls

54g and 54h on both sides of the tooth 54d, the rigidity of the rack 54 is improved. A support protrusion 54e (FIG. 5) is formed on the surface of the main body portion 54a facing the outer peripheral side opposite to the teeth 54d.

As shown in FIGS. 7 and 8, when the slider shoe 52 and the rack 54 are attached to the slider base 51, the stopper portion of the slider shoe 52 is extended (upward) on the extension of the tooth 54d of the rack 54 in the longitudinal direction of the slider base 51. 52c is located. At the upper end of the rack 54, a restricting portion 54f (FIG. 8) with which the outer peripheral surface of the stopper portion 52c abuts is formed.

A slide guide 55 is attached to the front edge side of the window glass W. As shown in FIG. 9, the slide guide 55 is a plate-shaped member whose both side surfaces are directed toward the inside and outside of the vehicle, and includes a mounting portion 55a located on the inner peripheral side and a protruding portion 55b protruding from the mounting portion 55a to the outer peripheral side. And a step portion 55c that connects the mounting portion 55a and the protruding portion 55b. The mounting portion 55a is located on the vehicle outer side than the projecting portion 55b, and the step portion 55c has an inclined shape that projects toward the vehicle outer side from the projecting portion 55b toward the mounting portion 55a. The surface of the mounting portion 55a that faces the vehicle exterior is fixed to the mounting region G2 (FIG. 4) of the vehicle interior side surface W2 of the window glass W by adhesion or the like.

As described above, the slider base 51, the pair of

slider shoes

52 and 53, the rack 54, and the slide guide 55 are attached to the window glass W to form the window assembly 50. When the window assembly 50 is incorporated into the door frame 10b, the state shown in FIGS. 5, 6 and 9 is obtained.

As shown in FIG. 6, in the upright pillar sash 12, the two upper and

lower slider shoes

52, 53 slide in the guide space S of the guide rail 40 in the longitudinal direction of the guide rail 40 (the vertical direction of the window glass W). It is movably housed. The vehicle interior side wall 41 surrounding the guide space S and the bent portion 45 restrict the movement of the slider shoes 52 and 53 in the vehicle interior and exterior directions. Further, the inner peripheral side wall 42 and the outer peripheral side wall 43 regulate the movement of the slider shoes 52, 53 in the inner and outer peripheral directions.

The first elastic contact portion 52b and the second elastic contact portion 52d provided on the slider shoe 52 come into contact with the vehicle interior side wall 41 and the outer peripheral side wall 43 to elastically deform, thereby preventing the slider shoe 52 from rattling. The first elastic contact portion 53b and the second elastic contact portion 53d provided on the slider shoe 53 contact the vehicle inner side wall 41 and the inner peripheral side wall 42 and elastically deform, thereby preventing the slider shoe 53 from rattling.

More specifically, the first

elastic contact portions

52b and 53b of the slider shoes 52 and 53 are pressed toward the vehicle outer side and elastically deformed in a state of being in contact with the vehicle interior side wall 41, respectively. The sliding

bases

52a and 53a are pressed to the outside of the vehicle by the force. The sliding

bases

52a and 53a pressed to the vehicle outer side are pressed against the bent portion 45 that partially covers the vehicle outer side of the guide space S, and are held in a stable state in the vehicle inward and outward directions.

The second elastic contact portion 52d of the slider shoe 52 is pressed toward the inner peripheral side and elastically deformed in a state of being in contact with the outer peripheral side wall 43, and the sliding base part is restored by the force to restore from the elastic deformation. 52a is pressed inward. The sliding base portion 52a pressed toward the inner peripheral side is pressed against the inner peripheral side wall 42 and is held in a stable state in the inner and outer peripheral directions.

The second elastic contact portion 53d of the slider shoe 53 is pressed toward the outer peripheral side and elastically deformed in a state of being in contact with the inner peripheral side wall 42, and the sliding base portion is caused by the force to restore from the elastic deformation. 53a is pressed to the outer peripheral side. The sliding base portion 53a pressed to the outer peripheral side is pressed against the outer peripheral side wall 43 and is held in a stable state in the inner and outer peripheral directions.

In this way, in the slider shoe 52 located on the upper end side of the trailing edge portion of the window glass W, the sliding base portion 52a is pressed to the inner peripheral side (front side) by the second elastic contact portion 52d protruding to the outer peripheral side, It is possible to absorb backlash to the outer peripheral side (rear). On the other hand, in the slider shoe 53 located on the lower end side of the trailing edge portion of the window glass W, the second elastic contact portion 53d protruding toward the inner peripheral side pushes the sliding base portion 53a toward the outer peripheral side (rearward), and It is possible to absorb backlash to the side (front). The functional sharing of the slider shoe 52 and the slider shoe 53 has the following advantages.

The window glass W has a shape in which the rear edge is longer in the vertical direction than the front edge, and the height of the upper edge gradually decreases from the rear edge to the front edge (FIGS. 1 to 4). reference). Therefore, the window glass W supported by the slider shoes 52 and 53 along the rear edge always receives a load in the forward tilt direction (counterclockwise as viewed from the inside of the vehicle as shown in FIG. 1). The load in the forward tilt direction acts as a force to move the slider shoe 52 on the upper side toward the inner peripheral side, and as a force to move the slider shoe 53 on the lower side toward the outer peripheral side. work. Here, in each

slider shoe

52, 53, the side surfaces of the sliding

base portions

52a, 53a having high strength and large area are brought into contact with the guide rail 40 (inner surface of the guide space S) in the acting direction of the load. Therefore, excellent load resistance can be obtained.

Further, when the vehicle body is violently vibrated due to traveling on a rough road, a load that tends to tilt the window glass W in the direction opposite to the forward tilt direction (clockwise when viewed from the inside of the vehicle as shown in FIG. 1) is applied. To work. This reverse load acts as a force for moving the slider shoe 52 on the upper end side to the outer peripheral side, and as a force for moving the slider shoe 53 on the lower end side to the inner peripheral side. work. Here, the slider shoes 52, 53 can efficiently suppress the vibration with respect to the guide rail 40 in the acting direction of the load while absorbing the load by elastic deformation of the second

elastic contact portions

52d, 53d.

The window glasses W move up and down as the slider shoes 52, 53 move along the inner surface of the guide space S. That is, the guide rail 40 functions as a guide portion for ascending and descending guides of the slider shoes 52 and 53 in the window regulator 19. The guide rail 40 has a curved shape corresponding to the curvature of the window glass W, and the slider shoes 52 and 53 can move the window glass W up and down with high accuracy along the curved guide rail 40.

Since the slider shoe 52 and the slider shoe 53 that form the window regulator 19 support the window glass W at a position that is largely apart in the vertical direction (the shoe pitch, which is the vertical gap between the two slider shoes 52 and 53), is large. The positional accuracy and stability of the glass W are extremely high. The larger the shoe pitch, the more easily the inclination of the window glass W with respect to the guide rail 40 (in particular, the inclination in the vehicle front-rear direction) can be suppressed, and highly accurate support and high stability of the window glass W can be obtained.

In particular, in the window glass W, the rear edge portion along the vertical pillar sash 12 is vertically longer than the front edge portion along the front sash 13. By arranging the slider shoe 52 and the slider shoe 53 so as to be spaced apart from each other near the upper end and the lower end of the rear edge of the window glass W, the effective vertical support length for the window glass W becomes very large, and Sufficient stability and support strength can be obtained even with a structure in which the window glass W is supported by the edge portion (the rear edge portion in the present embodiment) on one side. Further, in the wide space between the front sash 13 and the guide rail 40 in the inner space of the door panel, it is not necessary to provide means for supporting and guiding the window glass W, and excellent space efficiency can be obtained.

In the supporting structure on the side of the vertical pillar sash 12 that supports the window glass W with such excellent accuracy and stability, an elastic member that sandwiches and holds the window glass W in the inside and outside directions of the vehicle (a glass having a general concave structure) is used. Run) is not provided. The elastic covers 36 and 37 with which the vicinity of the rear edge of the window glass W abuts have waterproofness between the window glass W and the upright sash 12 (outer garnish 35), and also functions as an external component of the upright sash 12. Therefore, it is possible to make a compact and simple sectional shape.

The connecting portion 51b of the slider base 51 connects the slider shoes 52 and 53 arranged in the guide space S of the guide rail 40 and the glass fixing portion 51a located outside the guide space S (outside the vehicle). .. Therefore, the guide rail 40 has a cross-sectional shape in which the guide space S is opened to the outside of the vehicle in order to pass the connecting portion 51b inward and outward of the vehicle. The connecting portion 51b is an object to which the rack 54 is attached in addition to the slider shoes 52 and 53, and therefore extends in the vertical direction. As a result, the guide rail 40 has an opening portion to the outside of the vehicle over the entire longitudinal direction.

The lip portion 36b of the elastic cover 36 and the second lip portion 37d of the elastic cover 37 extend in the inner and outer peripheral directions, and in the free state, the vicinity of the tips thereof are overlapped with each other (see FIGS. 5 and 6). Therefore, at the cross-sectional position of the vertical column sash 12 in which the slider base 51 is present, the elastically deformed lip portion 36b and the second lip portion 37d are in close contact with the connecting portion 51b from both sides, and the vehicle fixing portion 51a is supported. Stick from the inside. As a result, the periphery of the slider base 51 can be reliably sealed. By extending the glass fixing portion 51a to a position on the outer peripheral side of the edge surface W3 of the window glass W, the contact range of the second lip portion 37d with respect to the glass fixing portion 51a can be secured. Further, at the cross-sectional position of the upright pillar sash 12 where the window glass W has descended and the slider base 51 does not exist, the open portion of the guide rail 40 facing the vehicle exterior side is overlapped with the lip portion 36b and the second lip portion 37d. cover. As a result, the internal structure of the upright sash 12 (particularly the guide rail 40) is not exposed in a state visible from the outside of the vehicle regardless of the vertical position of the window glass W, and the appearance quality of the upright sash 12 can be improved. ..

Further, since the elastic cover 36 and the elastic cover 37, which are separate bodies, are arranged separately in the inner peripheral side space and the outer peripheral side space divided by the connecting portion 51b of the slider base 51, the sealing performance in each space is improved. Easy to optimize. Specifically, on the inner peripheral side of the connecting portion 51b, an elastic cover 36 having a shape suitable for sealing between the vehicle interior side surface W2 of the window glass W and the guide rail 40 is arranged. An elastic cover 37 having a shape suitable for sealing between the edge surface W3 of the window glass W and the outer garnish 35 and between the outer garnish 35 and the guide rail 40 is provided on the outer peripheral side of the connection portion 51b. There is.

As shown in FIG. 5, in addition to the slider shoes 52 and 53, the rack 54 is also located in the guide space S of the guide rail 40. The main body portion 54a of the rack 54 has a smaller cross-sectional area than the sliding

base portions

52a and 53a of the slider shoes 52 and 53, and has a clearance with the inner surface of the guide space S. It does not hinder the vertical movement of the glass W. The teeth 54d of the rack 54 face the inner peripheral side (inner peripheral side wall 42) in the guide space S.

The guide rail 40 is extended longer than the inner sash 30 and the inner garnish 34, and has a length extending from the formation region of the upright pillar sash 12 overlapping with the inner sash 30 to the lowermost part of the inner space of the door panel. (See FIGS. 1 to 3). In the inner space of the door panel, the guide rail 40 is exposed without being surrounded by the inner sash 30 and the inner garnish 34. As shown in FIGS. 2 and 8, a part of the inner peripheral side wall 42 is cut out in the inner space of the door panel to form a notch 48 for exposing the teeth 54d of the rack 54. The pinion 61 of the drive unit 60 meshes with the teeth 54d of the rack 54 through the cutout 48.

The drive unit 60 includes a motor M, which is a drive source in the window regulator 19, and transmits the driving force of the motor M to the pinion 61 to rotate the pinion 61. The drive unit 60 is attached to the lock bracket 15. As shown in FIGS. 2 and 3, the lock bracket 15 is located on the inner side of the vehicle with respect to the inner sash 30, and a predetermined space is provided on the outer side of the lock bracket 15 in the door panel inner space below the inner sash 30. There is. The guide rail 40 passes through the space inside the door panel. The drive unit 60 is fixed to the surface of the lock bracket 15 on the vehicle outer side. In this state, the rotation shaft of the pinion 61 faces the inside of the vehicle.

When the drive unit 60 is attached to the predetermined position of the lock bracket 15, the pinion 61 meshes with the rack 54 from the inner peripheral side. The support protrusion 54e provided on the rack 54 is separated from the inner surface of the guide space S when no external force is applied. When a strong load is applied to the rack 54 from the pinion 61 (particularly, a force pressing the rack 54 toward the outer peripheral side), the support protrusion 54e contacts the outer peripheral side wall 43 and transfers the load to the guide rail 40. Thereby, excessive deformation of the rack 54 in the guide space S is prevented, and the meshing between the pinion 61 and the rack 54 is appropriately maintained.

By assembling the door components (door frame 10b, window assembly 50 and drive unit 60) including the components of the window regulator 19 as described above, the door frame assembly 10e including the window regulator 19 is configured. The door frame assembly 10e includes a door frame 10b and a window regulator 19 (see FIG. 2). FIG. 2 shows a state before the door frame assembly 10e is assembled.

When the motor M of the drive unit 60 is driven to rotate the pinion 61 with the window regulator 19 attached, the guide rail 40 is converted into a moving force in the longitudinal direction via the rack 54. Then, the slider base 51 to which the rack 54 is fixed moves together with the window glass W while sliding the slider shoes 52 and 53 with respect to the guide rail 40. Therefore, when the pinion 61 rotates forward and backward, the window assembly 50 including the rack 54 moves up and down along the guide rail 40. The rack 54 has a length that meshes with the pinion 61 in the entire movable range of the window glass W from the fully closed position to the fully open position.

When the window assembly 50 moves downward, the position of the slider shoe 52 attached to the upper end of the slider base 51 changes downward. Since the stopper portion 52c of the slider shoe 52 is located above (upper) the teeth 54d of the rack 54, when the position of the slider shoe 52 changes downward, the stopper portion 52c approaches the pinion 61. Then, as shown in FIG. 8, when the stopper portion 52c reaches the position of the pinion 61, the teeth of the pinion 61 come into contact with the side surface of the stopper portion 52c.

When the pinion 61 tries to rotate further in the glass descending direction (clockwise direction in FIG. 8) with the teeth of the pinion 61 in contact with the stopper portion 52c, the stopper portion 52c is pushed to the outer peripheral side. Since movement of the stopper portion 52c toward the outer peripheral side is restricted by a restriction portion 54f provided at the upper end of the rack 54, rotation of the pinion 61 in the glass descending direction is restricted. As a result, the pinion 61 and the rack 54 are locked, and the downward movement of the window glass W is mechanically limited. Since a mechanical stopper is configured by the slider shoe 52 that guides the up and down movement of the window glass W and the pinion 61 that applies the up-and-down driving force to the window glass W, it is not necessary to separately provide a stopper member, and the configuration is simple and low. You can get to the cost.

The mechanical limit position (FIG. 8) where the stopper portion 52c contacts the pinion 61 can be set to the fully open position of the window glass W. Alternatively, the fully open position of the window glass W to be moved by the normal drive control of the drive unit 60 is set above the mechanical limit position shown in FIG. 8, and the window glass W is moved by a predetermined amount in the opening direction from the fully open position. The stopper portion 52c may be configured to contact the pinion 61 only when it moves.

Note that the slider shoe 53 on the lower end side may be a dedicated part without the stopper portion 53c.

As shown in FIG. 9, the front sash 13 includes a vehicle interior side wall 70 located inside the vehicle interior, a connection wall 71 extending from the outer peripheral side end of the vehicle interior side wall 70 to the vehicle exterior side, and a vehicle exterior side end of the connection wall 71. And an outer side wall 72 extending from the inner peripheral side toward the inner peripheral side, and is open toward the inner peripheral side. In the inner and outer peripheral directions, the vehicle outer side wall 72 is located in front of the edge surface W3 of the front edge of the window glass W. The vehicle interior side wall 70 includes a base portion 70a connected to the connection wall 71, a tip portion 70b located on the tip end side and displaced to the vehicle exterior side with respect to the base portion 70a, and a step portion 70c connecting the base portion 70a and the tip end portion 70b. And have. The vehicle interior side wall 70 has a larger amount of protrusion toward the inner peripheral side than the vehicle outer side wall 72, and the tip portion 70b is located on the inner peripheral side of the vehicle outer side wall 72.

The front sash 13 has a fixing portion 73 protruding from the connecting wall 71 to the outer peripheral side, and the surface of the fixing portion 73 on the vehicle outer side is fixed to the mirror bracket 14. In addition, a surface of the inner side wall 70 on the vehicle inner side of the tip end portion 70 b is also fixed to the mirror bracket 14. Further, an exterior member 75 that covers the vehicle exterior side of the mirror bracket 14 is provided.

When the window assembly 50 is attached to the door frame 10b, the tip portion 70b of the vehicle interior side wall 70 of the front sash 13 is positioned so as to face the inside of the window glass W on the vehicle interior. The mounting portion 55a of the slide guide 55 mounted on the vehicle-interior side surface W2 on the front edge side of the window glass W (mounting area G2 shown in FIG. 4) faces the tip end portion 70b of the vehicle-interior side wall 70 in the vehicle-outside direction. The protruding portion 55b of the slide guide 55 is located between the base portion 70a of the vehicle interior side wall 70 and the vehicle exterior side wall 72 in the vehicle interior and exterior direction. Further, the exterior surface of the exterior member 75 and the exterior surface W1 of the window glass W are substantially flush with each other, and a flash surface structure similar to that of the upright sash 12 is obtained.

Elastic cover 76 and elastic cover 77 are attached to the front sash 13. Each of the elastic covers 76 and 77 is formed of a non-water-permeable elastic material (for example, rubber) and is a long member extending in the longitudinal direction of the front sash 13. FIG. 9 shows the shape of the elastic covers 76 and 77 in the initial state (free state) where no external force is applied.

The elastic cover 76 includes a fitting portion 76a that fits with the tip end portion 70b of the vehicle interior side wall 70 of the front sash 13 and the inner peripheral side end portion of the mirror bracket 14, and a cantilever shape protruding from the fitting portion 76a. It has a first lip portion 76b and a second lip portion 76c. The first lip portion 76b comes into contact with the vehicle interior side surface W2 of the window glass W and elastically deforms. The second lip portion 76c comes into contact with the mounting portion 55a of the slide guide 55 from inside the vehicle and elastically deforms.

The elastic cover 77 includes a fitting portion 77a fitted to the vehicle outer side wall 72 of the front sash 13, a cantilever-shaped first lip portion 77b protruding from the fitting portion 77a to the inner peripheral side, and a fitting portion 77a. It has a cantilevered second lip portion 77c that protrudes inward of the vehicle. The first lip portion 77b is located at a position facing the front edge surface W3 of the window glass W in the inner and outer peripheral directions. The first lip portion 77b is pushed toward the outer peripheral side by the edge surface W3 and elastically deforms. A part of the first lip portion 77b is located so as to fill a gap between the edge surface W3 of the window glass W and the inner peripheral side end portion of the exterior member 75, and constitutes a part of the outer surface of the door 10. The second lip portion 77c comes into contact with the protruding portion 55b of the slide guide 55 from the outside of the vehicle and elastically deforms.

The elastic cover 76 and the elastic cover 77 watertightly close the window glass W, the slide guide 55, the front sash 13, and the exterior member 75, and suppress the vibration of the window glass W. Further, the elastic cover 76 and the elastic cover 77 cover the internal structure of the front sash 13 so as not to be visually recognized from the inside of the vehicle, and improve the appearance near the front edge of the window glass W.

As shown in FIG. 9, the slide guide 55 only elastically contacts the elastic covers 76 and 77, and does not contact the front sash 13. As described above, the window regulator 19 provided on the vertical pillar sash 12 side can support and raise / lower the window glass W with high accuracy. Therefore, at the front edge of the window glass W, the front sash 13 and the slide guide 55 are separated from each other in a normal state so as not to affect the support and driving of the window glass W by the window regulator 19. When a strong external force equal to or more than a predetermined value is applied, the inner surface of the front sash 13 restricts the movement of the slide guide 55 to prevent the window glass W from falling off the door frame 10b.

As described above, in the door 10 of the present embodiment, the components (the guide rail 40, the slider base 51, the slider shoe 52) of the window regulator 19 that transfers the driving force of the motor M, which is the driving source, to the window glass W to move up and down. , 53, rack 54, etc.) are arranged so as to pass through the inside of the upright pillar sash 12. As a result, the space efficiency and layout can be improved around the door panel 10a as compared with the existing configuration in which the window regulator is arranged in the interior space of the door panel below the window opening 10c. For example, the degree of freedom in setting the shape of the door trim provided inside the door panel 10a is increased. In addition, the inner surface of the door can be made closer to the outer side of the vehicle to improve the handling of the foot when getting on or off, or the interior space of the door panel can be widened to secure a space for arranging functional parts other than the window regulator, It is possible to improve the assemblability of parts in the door panel 10a.

Also, since the mechanism for transmitting the driving force to the window glass W is configured by using the rack 54 and the pinion 61, the number of parts is small, which is advantageous in terms of simplicity of construction and productivity.

Further, the window regulator 19 is arranged inside the window glass W inside the vehicle, and the guide rail 40 holds the slider shoes 52 and 53 to restrict movement in both the inside and outside directions of the vehicle. Without sandwiching the window glass W, the movement of the slider shoes 52, 53 in the vehicle interior / outer direction is restricted only inside the vehicle interior of the window glass W. Therefore, the upright pillar sash 12 can be accommodated in the upright pillar sash 12 while avoiding the upsizing of the upright pillar sash 12 (in particular, the ups and downs of the vehicle).

Also, since the components of the window regulator 19 arranged along the vertical pillar sash 12 do not restrict the configuration of the window glass W on the outside of the vehicle, the outer surface of the door 10 can be designed more freely. Thus, a structure in which the vehicle outer surface W1 of the window glass W and the vehicle outer surface (outer garnish 35) of the upright sash 12 are substantially flush with each other can be adopted.

In the above-described embodiment, the slider base 51 and the slider shoes 52, 53 constitute a slider of the window regulator 19, and the window glass W is moved in the vertical direction with respect to the guide rail 40 via the slider. It is supported. Then, in addition to the glass fixing portion 51a fixed to the inner side surface W2 (inner surface) of the window glass W on the slider base 51, a lower end receiving portion 51c for supporting the lower end of the window glass W (the end edge in the opening / closing direction). By providing the above, the support strength of the window glass W by the slider base 51 is improved. In particular, the support by the lower end receiving portion 51c is effective for a load that attempts to relatively move the attachment region G1 of the vehicle interior side surface W2 and the glass fixing portion 51a in the vertical direction.

For example, at the fully closed position of the window glass W, the upper edge of the window glass W enters the glass run storage portion 23 of the upper sash 11 and the upward movement of the window glass W is restricted. In this state, if an excessive load is applied to move the slider base 51 further upward, the glass fixing portion 51a tends to shift upward with respect to the mounting region G1 of the vehicle interior side surface W2. Alternatively, when the drive unit 60 is stopped and the slider base 51 cannot move downward, if an excessive load that pushes the window glass W downward is applied, the attachment area of the vehicle interior side surface W2 with respect to the glass fixing portion 51a. G1 tries to shift downward. In any case, when the slider base 51 is used as a reference, a load is applied to relatively move the window glass W downward (in the opening operation direction). Here, in the slider base 51, the lower end receiving portion 51c is brought into contact with the lower end of the window glass W, and a load is applied at this abutting portion. Therefore, the shear load acting between the mounting region G1 and the glass fixing portion 51a is applied. Can be suppressed.

As described above, when the slider base 51 is used as a reference, it is assumed that a large load is applied in the opening / closing direction of the window glass W, particularly in the opening operation direction (downward). Therefore, it is preferable that the edge of the window glass W in the opening / closing direction (the lower end) is received by the slider base 51.

Further, even in a normal state in which an excessive load is not applied, since the lower end receiving portion 51c receives a part of the weight of the window glass W, the load is more dispersed than when the slider base 51 is fixed only in the mounting region G1. The effect is high, and the durability of the window assembly 50 is improved.

As shown in FIGS. 4 and 10 (B), the thickness of the lower end receiving portion 51c is larger than the thickness of the glass fixing portion 51a. Further, a lower end receiving portion 51c is provided continuously with the widened wide portion 51g formed at the lower end portion of the glass fixing portion 51a. As a result, the rigidity of the lower end receiving portion 51c and its vicinity is increased, and excellent load bearing performance can be obtained.

The lower end receiving portion 51c is in contact with a region of the lower end of the window glass W immediately below the mounting region G1. As shown in FIG. 4, in this region, the lower end of the window glass W extends substantially perpendicular to the vertical direction of the window glass W. The lower end receiving portion 51c also has a plate shape that is substantially perpendicular to the vertical direction of the window glass W. Therefore, the load acting in the up-and-down direction of the window glass W can be reliably received by the lower end receiving portion 51c.

Since the lower end receiving portion 51c has a simple configuration in which the lower end of the glass fixing portion 51a of the slider base 51 is bent, it is easy to manufacture and can be obtained at low cost. Further, since the lower end receiving portion 51c can be brought into a state of easily receiving the load by coming into contact with the lower end of the window glass W, a complicated assembling structure and assembling process are not required. Further, as described above, the slider base 51 can be positioned with respect to the window glass W (specifically, the positioning in the up-down direction) with reference to the state where the lower end receiving portion 51c abuts on the lower end of the window glass W.

As shown in FIG. 1, the lower end of the window glass W (the edge portion in the opening operation direction) is a portion that does not appear outside the door 10 in any state from the fully open state to the fully closed state of the window glass W. is there. Therefore, even if the lower end of the window glass W is supported by the lower end receiving portion 51c, the lower end receiving portion 51c is not visible from the outside, and the appearance quality of the door 10 is not affected.

In the slider base 51, the glass fixing portion 51a is fixed to the vehicle interior side surface W2 (mounting area G1) in a range extending over substantially the entire rear edge of the window glass W. Therefore, even when a load acts on any portion along the mounting region G1, the load can be transferred to the lower end receiving portion 51c, which is advantageous in strength.

Next, referring to FIG. 11 and subsequent figures, a plurality of modified examples to which the present invention is applied will be shown. In these modified examples, the portions denoted by the same reference numerals as those in the above-described embodiment have the same configurations and functions as those in the above-described embodiment, and description thereof will be omitted.

FIG. 11 shows a slider base 51 and a window glass W according to a first modification. In the first modified example, the lower end portion of the slider base 51 is extended from the lower end receiving portion (edge receiving portion) 51h to the outer surface side of the window glass W (a position along the vehicle outer surface W1) from the lower end receiving portion 51h. The outer surface receiving portion 51i has a hook shape. The lower end receiving portion 51h is a plate-shaped portion corresponding to the lower end receiving portion 51c of the above embodiment. An outer surface receiving portion 51i is formed by bending the tip (edge outside the vehicle) of the lower end receiving portion 51h upward. The window glass W is sandwiched inward and outward by the outer surface receiving portion 51i and the glass fixing portion 51a located on the vehicle outer side and the vehicle inner side with the lower end receiving portion 51h interposed therebetween. The outer surface receiving portion 51i prevents the vicinity of the lower end of the window glass W from moving outside the vehicle relative to the slider base 51. Thereby, the support strength and stability of the window glass W by the slider base 51 can be improved.

FIG. 12 shows a slider base 80 and a window glass W according to a second modification. The slider base 80 has a glass fixing portion 80a that is fixed to the mounting region G1 of the vehicle side surface W2 of the window glass W by adhesion or the like. The rack 54 is attached to a connecting portion (not shown) protruding from the glass fixing portion 80a to the inside of the vehicle.

The slider base 80 has a front extending portion 80b that extends forward from the lower end of a glass fixing portion 80a that extends substantially vertically. A lower end receiving portion (edge receiving portion) 80c and an outer surface receiving portion 80d are formed near the front end of the front extending portion 80b. The lower end receiving portion 80c is a flat plate-shaped portion that projects from the front extending portion 80b to the outside of the vehicle. The protruding amount of the lower end receiving portion 80c from the front extending portion 80b to the outside of the vehicle is equal to or larger than the thickness of the window glass W. The outer surface receiving portion 80d is a portion in which the edge of the lower end receiving portion 81c on the vehicle outer side is bent upward.

The lower end receiving portion 80c has a function of receiving the lower end (edge surface W3) of the window glass W from below, like the lower

end receiving portions

51c and 51h described above. The lower end receiving portion 80c serves as a vertical position reference, and the slider base 80 can be accurately fixed to the window glass W. Further, by receiving the lower end of the window glass W by the lower end receiving portion 80c, it is possible to reliably prevent the positional displacement or separation of the window glass W with respect to the slider base 80 in the up-down direction (opening / closing direction).

The lower end receiving portion 80c is arranged in front of a position (a position below the mounting area G1) where the glass fixing portion 80a is fixed to the mounting area G1 of the window glass W. According to this slider base 80, with respect to the load that the window glass W tends to tilt in the front-rear direction, particularly, the load in the forward tilt direction of the window glass W (counterclockwise when viewed from the inside of the vehicle as shown in FIG. 12), Excellent load resistance can be obtained. The position of the lower end receiving portion 80c in the vehicle front-rear direction (the amount of offset to the front with respect to the glass fixing portion 80a) can be arbitrarily set according to the space efficiency of the peripheral structure and the load bearing performance to be ensured. As an example, the position of the lower end receiving portion 80c may be set ahead of the center of gravity of the window glass W.

Similar to the outer surface receiving portion 51i described above, the outer surface receiving portion 80d is located along the vehicle outer surface W1 of the window glass W and prevents the vicinity of the lower end of the window glass W from moving to the vehicle outer side with respect to the slider base 80. .. This improves the support strength and stability of the window glass W by the slider base 80.

The front extending portion 80b shown in FIG. 12 linearly extends from the glass fixing portion 80a toward the front, but is not limited to this configuration. The extension portion of the slider corresponding to the front extension portion 80b only needs to meet the requirement that it extends in the direction intersecting the opening / closing direction of the window glass W, and there are variations in the extension direction and shape of the extension portion. Can have For example, it is possible to use an extending portion that extends obliquely downward or upward with respect to the glass fixing portion 80a. Further, it is also possible to use an extending portion having a shape in which the width in the vertical direction is gradually narrowed (or widened) as it goes forward from the portion connected to the glass fixing portion 80a. In short, the support means (lower end receiving portion 80c) for supporting the window glass W separately from the glass fixing portion 80a can be arranged at a position which is not on the extension of the glass fixing portion 80a in the longitudinal direction (opening and closing direction of the window glass W). Any configuration will do.

FIG. 13 shows a slider base 81 and a window glass W according to a third modification. The glass fixing portion 81a of the slider base 81 is fixed to the mounting region G1 of the vehicle side W2 of the window glass W by adhesion or the like. A widened portion 81b that widens toward the front of the vehicle is formed at the lower end of the glass fixing portion 81a, and a lower end receiving portion 81c extends from the widened portion 81b toward the outside of the vehicle. An outer surface receiving portion 81d is formed by bending the outer edge of the lower end receiving portion 81c toward the upper side. The lower end receiving portion 81c and the outer surface receiving portion 81d function similarly to the lower end receiving portion 51h and the outer surface receiving portion 51i of the first modified example (FIG. 11).

The window glass W has a fitting recess W4 that is cut out toward the front of the vehicle on an edge surface W3 on the vehicle rear side along the attachment region G1. Since the edge surface W3 of the window glass W on the vehicle rear side extends along the up-and-down direction (opening and closing direction) of the window glass W, the fitting recess W4 formed on the edge surface W3 of the vehicle rear side is the window glass. It has upper and lower edges facing each other in the ascending and descending direction of W. The fitting recess W4 is located between both ends (upper end and lower end) in the opening / closing direction of the window glass W. In particular, the fitting recess W4 is located at a position closer to the lower end of the window glass W in the opening / closing direction so as to be located below the upper edge of the belt line reinforcement 16 at the fully closed position of the window glass W (FIG. 1). Since it is formed, the fitting recess W4 does not appear in the appearance (inside the window opening 10c).

A fitting portion 81e is formed on the slider base 81. The fitting portion 81e has a portion projecting from the glass fixing portion 81a to the outside of the vehicle, and the fitting portion 81e is fixed to the attachment region G1 of the window glass W by adhesion or the like. To fit. When a force is applied to relatively move the window glass W (the mounting area G1 of the vehicle interior side surface W2) and the glass fixing portion 81a in the vertical direction, the fitting portion 81e contacts the upper and lower edges of the fitting recess W4. Can receive the load.

Thus, in addition to the fixing of the glass fixing portion 81a to the attachment region G1 of the vehicle interior side surface W2, the fitting recess W4 and the fitting portion 81e are fitted to each other, so that the support strength of the window glass W by the slider base 81 is increased. Is improved. In particular, since the upper and lower edges of the fitting recess W4 are in contact with the fitting portion 81e to receive a load, it is possible to avoid a shear load that attempts to move the mounting region G1 and the glass fixing portion 81a relative to each other in the vertical direction. On the other hand, it is advantageous in terms of strength.

In the configuration of FIG. 13, the fitting of the fitting portion 81e into the fitting recess W4 and the support of the lower end receiving portion 81c with respect to the lower end of the window glass W are used together. If sufficient support strength can be secured at the fitting portion of 81e, the support by the lower end receiving portion 81c may be omitted.

FIG. 14 shows a slider base 82 and a window glass W according to a fourth modification. The slider base 82 includes a glass fixing portion 82a fixed to the mounting region G1 of the vehicle side W2 of the window glass W by adhesion or the like, and a front extending portion 82b extending forward from the lower end of the glass fixing portion 82a. Have The front extending portion 82b is a plate-shaped portion along the vicinity of the lower edge of the vehicle interior side surface W2 of the window glass W.

The front extension portion 82b of the slider base 82 is formed with two

holes

82c and 82d at different positions in the vehicle front-rear direction (direction intersecting the opening / closing direction of the window glass W). Each of the

holes

82c and 82d penetrates the front extension portion 82b in the vehicle inward and outward directions. The hole 82c on the front side is a round hole having a perfect circle shape, and the hole 82d on the rear side is a long hole elongated in the front-rear direction.

In the window glass W, two holes W5, W6 are formed in a region overlapping the front extension 82b at different positions in the vehicle front-rear direction (direction intersecting the opening / closing direction of the window glass W). The holes W5 and W6 are located between both ends (upper end and lower end) in the opening / closing direction of the window glass W, and are particularly arranged at positions closer to the lower end of the window glass W in the opening / closing direction. Each of the holes W5 and W6 penetrates the window glass W in the inside and outside directions of the vehicle. The front hole W5 is a round hole having a perfect circle shape, and the rear hole W6 is a long hole that is long in the front-rear direction.

The

holes

82c and 82d on the slider base 82 side and the holes W5 and W6 on the window glass W side are provided in a positional relationship corresponding to each other. The slider base 82 is aligned with the window glass W so that the hole 82c, which is a round hole, communicates with the hole W5, and the hole 82d, which is a long hole, communicates with the hole W6. Then, a bolt (supporting means, fastening member) 91 is inserted into the hole 82c and the hole W5 and screwed into the nut 92. Further, a bolt (supporting means, fastening member) 93 is inserted into the hole 82d and the hole W6 and screwed into the nut 94. The heads of the

bolts

91 and 93 come into contact with the inner surface of the front extension portion 82b of the slider base 82 (a washer or the like is interposed if necessary), and the nuts 92 and 94 are attached to the outer surface of the window glass W. The front extension portion 82b is fastened and fixed to the window glass W by abutting against W1 (interposing a washer or the like if necessary) and applying a predetermined tightening torque to each

bolt

91, 93.

Since the hole 82d and the hole W6 are long holes, it is possible to absorb the systematic error and assembly error of the parts in the vehicle front-rear direction when the hole 82c and the hole W5 are used as a reference. Further, the front extending portion 82b is arranged so as to be located below the upper edge of the belt line reinforcement 16 at the fully closed position (FIG. 1) of the window glass W, and the

bolts

91, 93 and the nut 92. , 94 does not appear in the appearance (inside the window opening 10c).

In addition to fixing the glass fixing portion 82a to the mounting region G1 of the vehicle interior side surface W2, the front base extension portion 82b is fastened via the

bolts

91, 93 and the nuts 92, 94 to support the window glass W by the slider base 82. Is improved. Particularly, since the inner surfaces (edges) of the holes W5, W6 formed in the window glass W are in contact with the shaft portions of the

bolts

91, 93 mounted on the slider base 82 to receive a load, the mounting area G1 is This is advantageous in terms of strength against a load that attempts to relatively move the glass fixing portion 82a in the vertical direction.

Further, since the front extending portion 82b is fastened to the window glass W at two different positions in the vehicle front-rear direction that intersect with the opening / closing direction of the window glass W, the inclination of the window glass W in the front-rear direction is prevented. The suppressing effect is obtained. In particular, it is possible to obtain excellent load resistance against a load in the forward tilt direction (counterclockwise when viewed from the inside of the vehicle as shown in FIG. 14) which constantly acts on the window glass W. The front extending portion 82b may be fixed to the window glass W only by fastening with the

bolts

91 and 93 and the nuts 92 and 94, or in addition to fastening, adhesion to the vehicle interior side surface W2 may be used together.

As the plurality of fastening members, the two

bolts

91 and 93 are used in the configuration of FIG. 14, but it is also possible to use three or more fastening members. In addition, the fastening points of the plurality of fastening members may satisfy the requirement that the positions are different in the direction intersecting the opening / closing direction of the window glass W. For example, in the configuration of FIG. 14, the fastening points by the two

bolts

91 and 93 are arranged so as to be lined up in the vehicle front-rear direction substantially orthogonal to the opening / closing direction of the window glass W, but fastening by a plurality of fastening members. The positions may be different not only in the front-rear direction of the vehicle but also in the vertical direction (generally corresponding to the opening / closing direction of the window glass W).

FIG. 15 shows a slider base 83 and a window glass W according to a fifth modification. The slider base 83 is provided with a glass fixing portion 83a fixed to the mounting region G1 on the vehicle interior side surface W2 of the window glass W by adhesion or the like, and a widening portion provided at the lower end of the glass fixing portion 83a and widened toward the front of the vehicle. 83b.

A widened portion 83b of the slider base 83 is formed with a hole 83c penetrating inward and outward of the vehicle. In the window glass W, a hole W7 is formed at a position corresponding to the hole 83c on the slider base 83 side so as to penetrate in the inside / outside direction of the vehicle. The hole W7 is located between both ends (upper end and lower end) in the opening / closing direction of the window glass W, and is particularly arranged at a position near the lower end of the window glass W in the opening / closing direction. Each of the hole 83c and the hole W7 is a non-circular hole (square hole or the like).

Insert the bolt (supporting means, fastening member) 95 into the hole 83c and the hole W7 and screw it into the nut 96. The head of the bolt 95 contacts the inner surface of the widened portion 83b of the slider base 83 (with a washer or the like if necessary), and the nut 96 contacts the outer surface W1 of the window glass W (if necessary). The widened portion 83b is fastened and fixed to the window glass W by applying a predetermined tightening torque to the bolt 95. The bolt 95 has a non-circular cross-sectional shape corresponding to the hole 83c and the hole W7, and a state in which rotation of each inner surface (edge) of the hole 83c and the hole W7 is restricted with respect to the inserted bolt 95. become.

The widened portion 83b is arranged below the upper edge of the belt line reinforcement 16 at the fully closed position (FIG. 1) of the window glass W, and the fastening portion by the bolt 95 and the nut 96 does not appear in the appearance. ..

In addition to fixing the glass fixing portion 83a to the mounting area G1 of the vehicle interior side surface W2, fastening the widened portion 83b through the bolt 95 and the nut 96 improves the support strength of the window glass W by the slider base 83. In particular, since the edge of the hole W7 formed in the window glass W abuts against the shaft portion of the bolt 95 and receives a load, the mounting region G1 and the glass fixing portion 83a are attempted to move relative to each other in the vertical direction. It is advantageous in strength against load.

Further, since the holes 83c, the holes W7, and the shaft portions of the bolts 95 are each formed into a non-circular shape to restrict the relative rotation of the window glass W and the slider base 83 with respect to the bolts 95, the inclination of the window glass W to the front and back is suppressed. The effect is obtained. In particular, it is possible to obtain excellent load resistance against a load in the forward tilt direction (counterclockwise when viewed from the inside of the vehicle as shown in FIG. 15) that constantly acts on the window glass W.

Note that the widened portion 83b may be fixed to the window glass W only by fastening with the bolts 95 and the nuts 96, or in addition to fastening, bonding to the vehicle inner side surface W2 may be used together.

As shown in each of the modified examples of FIGS. 13 to 15, as the supporting means for restricting the movement of the window glass W in the opening / closing direction with respect to the slider (slider base), the edge portion at the end of the window glass W in the opening / closing direction is supported. It is also possible to use a structure other than the edge receiving part (a structure that fits into a recess or hole formed in the window glass W).

The sixth modification shown in FIGS. 16 and 17 is a modification of the slide guide 55 provided on the front edge side of the window glass W and the configuration of the front sash 13 in the door frame 10b.

The slider base 84 shown in FIG. 16 has a glass fixing portion 84a, a widening portion 84b, a lower end receiving portion 84c, and an outer surface receiving portion 84d. Each of these parts of the slider base 84 has the same configuration and function as the glass fixing part 81a, the widening part 81b, the lower end receiving part 81c, and the outer surface receiving part 81d in the slider base 81 of the above-described third modification (FIG. 13). Have Although omitted in FIG. 16, the slider shoes 52, 53 attached to the slider base 84 are guided by the guide rails 40 provided on the upright pillar sash 12 so as to be slidable in the vertical direction of the window glass W.

The slide guide 55 attached to the front edge side of the window glass W has a bent portion 55d in addition to the attachment portion 55a, the protruding portion 55b, and the step portion 55c described in the above embodiment. The bent portion 55d has a shape in which an end portion of the protruding portion 55b on the vehicle front side (outer peripheral side) is bent toward the vehicle outer side.

As shown in FIG. 17, the front sash 13 has a bent portion 74 in addition to the vehicle interior side wall 70, the connection wall 71, the vehicle exterior side wall 72, and the fixed portion 73 described in the above embodiment. The bent portion 74 has a shape obtained by bending an end of the vehicle outer side wall 72 on the vehicle rear side (inner circumferential side) toward the vehicle inner side. Although not shown in FIG. 17, the front sash 13 is provided with an elastic cover corresponding to the elastic cover 76 and the elastic cover 77 described above.

As shown in FIG. 17, the connection wall 71, the vehicle exterior side wall 72, and the bent portion 74 of the front sash 13 form a U-shaped space open toward the vehicle interior. The bent portion 55d of the slide guide 55 enters the space on the side of the front sash 13 from the inside of the vehicle toward the outside of the vehicle. In the vehicle front-rear direction (inner and outer peripheral direction), the bent portion 55d is located closer to the bent portion 74 than the connecting wall 71.

In the sixth modified example described above, the front sash 13 and the slide guide 55 are separated from each other in a normal state so as not to affect the support and drive of the window glass W via the slider base 84. Then, when a strong external force of a predetermined amount or more is applied, the inner surface of the front sash 13 restricts the movement of the slide guide 55 to prevent the window glass W from falling off the door frame 10b. In particular, by providing the bent portion 55d and the bent portion 74 that are opposed to each other in the vehicle front-rear direction (inner and outer peripheral direction), an effect of limiting the inclination of the window glass W in the vehicle front-rear direction can be obtained. Since the slide guide 55 (the bent portion 55d) and the front sash 13 (the bent portion 74) limit the inclination on the front edge side opposite to the rear edge side of the window glass W on which the slider base 84 (window regulator) is arranged, The effect of suppressing the inclination of the window glass W is high.

As described above, in the slider structure of the vehicle door of the present invention, in addition to the inner surface fixing portion of the slider (slider base) fixed to the inner surface of the window glass W that is the opening / closing body (vehicle inner side surface W2), the slider A support means (lower

end receiving portions

bolts

91, 93, 95). Thus, the load of the opening / closing direction acting between the inner surface of the opening / closing body and the inner surface fixing portion can be received by the supporting means, and the support strength of the opening / closing body by the slider can be increased.

The portion of the window glass W to be supported by the supporting means (a portion other than the vehicle interior side surface W2) may be a portion that can receive the load acting in the opening / closing direction of the window glass W by the supporting means. The above-described edge surface W3 of the window glass W, the inner surface of the fitting recess W4, and the inner surfaces of the holes W5, 6, 7 are portions having a width in the vehicle interior / outer direction according to the thickness of the window glass W, and are supported. Approved by means of support.

In the above embodiment, the lower end receiving portion 51c of the slider base 51 is in contact with the lower end of the window glass W when the window assembly 50 is assembled. Unlike this configuration, it is possible to set the lower end receiving portion 51c to be slightly separated from the lower end of the window glass W during assembly. When an excessive load is applied to the window glass W and the window glass W is displaced slightly downward with respect to the glass fixing portion 51a in the fixing area along the attachment area G1, the lower end of the window glass W hits the lower end receiving portion 51c. In contact with each other, further positional deviation is restricted. The lower

end receiving portions

51h, 80c, 81c, 84c, the fitting portion 81e, and the

bolts

91, 93, 95 in each modified example can be configured similarly to the lower end receiving portion 51c.

Between the window glass W and the slider base 51 (80, 81, 82, 83, 84), a load that moves the window glass W relatively downward often acts. Therefore, as in the above-described embodiment and the first, second, third, and sixth modifications, the edge receiving portions (lower

end receiving portions

51c, 51h, 80c, 81c, 84c) that support the lower end of the window glass W. Is preferably provided on the slider. However, it is also possible to modify the slider such that an edge receiving portion that supports the upper end of the window glass W is provided on the slider. That is, the edge receiving portion may support either the edge on the lower end side which is the end in the opening operation direction of the window glass W or the edge on the upper end side which is the end in the closing operation direction. In addition, a pair of upper and lower edge receiving portions that support both the lower end and the upper end of the window glass W (the end edge portions in both the opening operation direction and the closing operation direction) may be provided on the slider.

In each of the third, fourth, and fifth modifications, the fitting recess W4 and the holes W5, W6, W7 formed in the window glass W have a shape having upper and lower edges, respectively. Therefore, even if the slider base is not provided with the edge receiving portions that support the lower end and the upper end of the window glass W, the fitting portion 81e and the

bolts

91, 93, and 95, which are fastening members, are used as supporting means to open and close (elevate) in both directions. The support (movement regulation) of the window glass W can be realized.

On the other hand, as in the first embodiment, the first modification, the second modification, and the sixth modification, the edge of the window glass W (the edge at the lower end that is the end in the opening direction in the above-described configuration) is attached to the edge receiving portion of the slider base. The structure supported by means can be realized without processing recesses or holes in the window glass W, which is advantageous in terms of manufacturing labor and cost. In addition, the configuration in which the peripheral edge of the window glass W is supported by the edge receiving portion is not restricted by the size and shape of the recesses or holes on the side of the window glass W, and thus the degree of freedom in setting the support range and the supporting length by the edge receiving portion is high. It has the advantage of being expensive.

As described above, various configurations can be selected as the support means that regulates the movement of the window glass W that is the opening / closing body in the opening / closing direction, and each configuration is unique in terms of support strength, productivity, cost, space efficiency, and the like. Have advantages. Taking these advantages into consideration, it is possible to appropriately employ a supporting means of a type suitable for each vehicle door.
