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 vertical pillar sash 12 is configured by combining the inner sash 30 which is a long member and the guide rail 40. The guide rail 40 is a component of the window regulator 19 described later. 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 step portion 33 of the inner sash 30 and the outer peripheral extension portion 44 of the guide rail 40 overlap each other 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 formed of a non-water-permeable elastic material (for example, rubber) and is a long member extending in the longitudinal direction of the upright pole 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 and suppressing vibration around the window glass W in this 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 to the outside of the vehicle is pressed by the inside surface W2 of the window glass W, and the hollow portion 36a is compressed and deformed in the inside and outside directions of the vehicle. 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 the sealing by the first lip portion 37c for the edge surface W3 of the window glass W and the sealing by the hollow portion 36a for 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 and 37 function as a seal member by being pressed by the window glass W, when the positional relationship between the window glass W and the elastic covers 36 and 37 is stable, the elastic covers 36 and 37 are not attached to the respective portions of the window glass W and the upright sash 12. The degree of adhesion between 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. The window regulator 19 constitutes an example of an opening / closing body drive device. As shown in FIGS. 2 and 3, the window regulator 19 supports and guides the window assembly 50 by the guide rails 40 so as to be movable in the vertical direction, and transmits the driving force of the drive unit 60 to the window assembly 50 to transmit the window glass. Raise and lower W.

The window regulator 19 of the present embodiment has its constituent elements divided and some of the constituent elements are assembled to the door constituent parts (door frame 10b and window assembly 50). More specifically, the window regulator 19 is divided into a guide rail 40, a slider base 51, slider shoes 52 and 53, a rack 54, and a drive unit 60. The slider base 51 and the slider shoes 52, 53 constitute an example of a guided member, and the rack 54 constitutes an example of a driven member. The guide rail 40 is assembled to the door frame 10b (standing pillar sash 12), and the slider base 51, slider shoes 52 and 53, and the rack 54 are assembled to the window glass W. The window regulator 19 is configured to be completed in the process of assembling these door components. The components of the window regulator 19 are incorporated inside or around the upright pole sash 12. The configuration of the window assembly 50 including the components of the window regulator 19 will be described below.

As shown in FIG. 4, the window assembly 50 is configured by assembling a slider base 51, a pair of

slider shoes

52 and 53, a rack 54, and a slide guide 55 on a window glass 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 extends from the vicinity of the upper end of the rear edge of the window glass W to the vicinity of the lower end thereof. 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 51a located outside the vehicle and a connecting portion 51b protruding from the glass fixing portion 51a to the inside of the vehicle, and has a substantially T-shaped cross section perpendicular to the longitudinal direction. ..

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 FIG. 4, a lower end 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.

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 with the lower end receiving portion 51c provided on the slider base 51, the window glass W and the slider base 51 can be fixed 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. The

shoe support portions

51d and 51e each have 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. .

The fixing screw 56 (FIG. 4) is inserted into the holes formed in the sliding

bases

52a and 53a, and the fixing screw 56 is screwed 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

side wall portions

54g and 54h forming the body portion 54a. The rigidity of the rack 54 is improved by providing the

side walls

54g and 54h on both sides of the tooth 54d. 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 window base 50 is formed by attaching the slider base 51, the pair of

slider shoes

52 and 53, the rack 54, and the slide guide 55 to the window glass W, respectively.

Such a window assembly 50 is assembled to the door frame 10b to which the guide rail 40 is attached. The window assembly 50 is assembled so that the rack 54 and the slider base 51 are accommodated in the guide space S of the guide rail 40 from the outside of the vehicle. When the rack 54 and the slider base 51 are thus assembled in the door frame 10b so as to be housed in the guide space S, the window assembly 50 is in the state shown in FIGS. 5, 6, and 9.

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

lower slider shoes

52 and 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 regulate the movement of the slider shoes 52, 53 in the vehicle interior and exterior directions. 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 inner 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, each

slider shoe

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 the 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 which form the window regulator 19 support the window glass W at a position that is largely separated in the vertical direction (the shoe pitch, which is the vertical interval between the two

slider shoes

52 and 53, is large), the window 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 a target 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 pillar sash 12 where 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 attached to the glass fixing portion 51a. 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 54a of the rack 54 has a smaller cross-sectional area than the sliding

bases

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.

In the above embodiment, the step of attaching the guide rail 40 as a part of the upright pillar sash 12, the step of attaching the window glass W to the guide rail 40 so that the slider base 51 and the rack 54 are housed in the guide space S, and the window glass The window regulator 19 is assembled by performing a step of engaging a part of the drive unit 60 (pinion 61) with the rack 54 fixed to W. According to this assembling method, the window glass W is attached to the guide rail 40 attached as a part of the upright pillar sash 12, and the drive unit 60 is attached to the window glass W. As a result, the work of assembling each member can be performed on the basis of the upright pillar sash 12, so that the work of assembling can be facilitated as compared with the case of performing the work on the basis of two or more members.

The window glass W is attached to the guide rail 40 in advance so that the slider base 51 and the rack 54 are housed in the guide space S, and the guide rail 40 in that state is attached as a part of the upright pillar sash 12; The window regulator 19 may be assembled by performing a step of engaging a part of the drive unit 60 (pinion 61) with the rack 54 of the glass W. According to this assembling method, as in the above-described assembling method, the work of assembling the members can be performed with the vertical pillar sash 12 as a reference, so that compared with the case of performing the work of assembling with two or more members as a reference, Assembly work can be facilitated. Further, since the guide rail 40 is attached to the door frame 10b in the state where the window glass W is attached, it is possible to reduce the steps until the window regulator 19 is assembled.

Further, all the constituent elements (guide rail 40, window assembly 50 and drive unit 60) may be assembled in advance to form a unit, and the unit may be assembled to the door frame 10b. According to this assembling method, since the guide rail 40 is attached to the door frame 10b with the window assembly 50 and the drive unit 60 attached, it is possible to further reduce the step of assembling the window regulator 19.

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.

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, racks 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 located 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 directions inside and outside the vehicle. Without interposing the window glass W, movement of the slider shoes 52, 53 in the vehicle interior and exterior directions 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.

Further, the window regulator 19 is provided with a guide rail 40 that constitutes a part of the upright pillar sash 12, and a slider base 51 and a rack 54 that are at least partially housed in a guide space S in the guide rail 40 (fixed.

On the other hand, the rack 54 receives a driving force for lifting drive from the drive unit 60. The slider base 51 and the rack 54 are provided (fixed) on the window glass W. Therefore, since the guide function and the drive function for the window glass W can be integrated in the upright pillar sash 12, the window glass W can be lifted and lowered without requiring a special configuration such as a division bar. Moreover, since the assembling work of each member can be performed with the vertical pillar sash 12 as a reference, the assembling work can be facilitated as compared with the case where the assembling work is performed with two or more members as a reference.

In particular, in the window regulator 19, the guide rail 40 is attached as a part of the upright pillar sash 12. With this, the guide rail 40 can be configured separately from the other elements (the inner sash 30) of the upright pillar sash 12, so that the restrictions at the time of manufacturing the guide rail 40 can be reduced and the manufacturing cost can be reduced. Further, since the work of assembling the wind regulator 19 can be performed separately from the other components (inner sash 30) of the upright sash 12, it is possible to increase the choice of work processes during the work of assembling.

Further, in the window regulator 19, the slider base 51 is arranged so as to extend from the vicinity of the upper end of the window glass W to the vicinity of the lower end thereof. For this reason, since the slider base 51 is arranged over a wide area in the vertical direction of the window glass W, the guide rail 40 can guide almost the entire window glass W in the up-and-down direction. The lifting operation can be stabilized.

Further, in the window regulator 19, the rack 54 is fixed to the slider base 51. As a result, the driving force of the driving unit 60 (more specifically, the motor M) can be directly transmitted to the slider base 51 via the rack 54, so that the loss at the time of transmitting the driving force can be suppressed and the window can be suppressed. It is possible to stabilize the vertical movement of the glass W.

Further, the drive unit 60 is indirectly fixed to the upright pole sash 12 via the lock bracket 15. As a result, the drive unit 60 and the rack 54 that receives the drive force can be positioned with the vertical pillar sash 12 as a reference, so that the drive force can be stably provided to the rack 54.

The above embodiment is applied to the side door attached to the side of the right front seat of the vehicle, but can be applied to other doors.

In the above embodiment, the case where the guide rail 40 is attached as a part of the upright pillar sash 12 has been described, but the configuration of the guide rail 40 is not limited to this and can be changed as appropriate. For example, the guide rail 40 may be configured integrally with the door frame 10b.

In the above embodiment, the case where the slider base 51 is arranged so as to extend from the vicinity of the upper end to the vicinity of the lower end at the trailing edge of the window glass W is described, but the configuration of the slider base 51 is not limited to this. Instead, it can be changed appropriately. For example, the slider base 51 may be arranged in different areas of the window glass W. Further, the slider base 51 may be divided into a plurality of parts and fixed to the window glass W.

Furthermore, in the above embodiment, the case where the slider base 51 and the rack 54 are fixed to the window glass W has been described, but the configuration of the window glass W is not limited to this and can be changed as appropriate. The slider base 51 and the rack 54 do not necessarily have to be fixed to the window glass W, and may be provided on a part of the window glass W.

Further, in the above embodiment, the case where the rack 54 is fixed to the slider base 51 has been described (see FIGS. 4 and 5), but the fixing portion of the rack 54 is not limited to the slider base 51 and may be changed as appropriate. It is possible. The rack 54 may be fixed to a configuration other than the slider base 51 on the assumption that it is housed in the guide space S of the guide rail 40. Further, the fixing method for the slider base 51 is not limited to the fixing screw 57, and any fixing method can be selected.

Further, in the above-described embodiment, the case where the drive unit 60 is indirectly fixed to the upright pole sash 12 via the lock bracket 15 has been described, but the fixing method of the drive unit 60 is not limited to this, and is appropriately changed. It is possible. For example, the drive unit 60 may be indirectly fixed to the upright pole sash 12 via a different member, or may be directly fixed to the upright pole sash 12 (for example, the inner sash 30).

The direction position is determined. The ribs 83c are located on the back side of the teeth 83a, and when a load is applied from the side of the pinion 87 that meshes with the teeth 83a, the ribs 83c receive the load at the portions in contact with the outer peripheral side wall 80c. The rib 83b is located on the opposite side of the portion of the slider base 81 connected to the connecting portion 81b, and when a load from the window glass W or the slider base 81 to the inside of the vehicle is applied, the rib 83b is attached to the inside wall 80a of the vehicle. The load is received at the abutting part. As a result, the position of the rack 83 is stable, the accuracy of engagement with the pinion 87 is improved, and smooth and stable driving of the window glass W can be realized.

As described above, the guide rail 80 is assembled to the inner panel 100 via the mounting bracket 90, and the slider base 81, the slider shoe 82, and the rack 83 are assembled to the window glass W. The window regulator is completed in the process of assembling these door components. The components of the window regulator are incorporated inside or around the upright pillar sash 101. With the window regulator configured, the drive unit 84 is located below the window opening and does not appear in the appearance.

Assembling the window regulator to the vertical pillar sash 101 can be performed by any procedure. As an example, the mounting bracket 90 is fixed to the inner panel 100 in advance, and then the guide rail 80 is mounted to the inner panel 100. The step of mounting the guide rail 80 includes fastening and fixing the guide rail 80 to the mounting bracket 90. Before the window glass W is assembled, the

cutout portions

80g, 80h of the guide rail 80 are exposed toward the vehicle exterior side (see FIG. 10), so the

bolts

91, 93, 95 are inserted from the vehicle exterior side. It is easy to perform the work to fasten. The slider base 81, slider shoe 82, and rack 83 are assembled to the guide rail 80 after attachment. The slider base 81 may be fixed to the window glass W before the slider base 81 is attached to the guide rail 80 or after the slider base 81 is attached to the guide rail 80. Further, the drive unit 84 is assembled to the guide rail 80 (see FIGS. 15 and 16). The drive unit 84 is assembled after inserting the rack 83 into the guide rail 80.

The guide rail 80 (support legs 85, 86) can be attached to the attachment bracket 90 by means other than fastening with bolts. For example, the guide rail 80 may be fixed to the mounting bracket 90 by spot welding, friction stir welding, or the like.

In the illustrated form, the mounting structure of the guide rail 80 via the mounting bracket 90 is applied to a part of the upper side of the guide rail 80. This is because the drive unit 84 is attached in the middle of the guide rail 80 in the longitudinal direction, and various mechanisms (door locks and door opening / closing related members) are arranged inside the door below the upright pillar sash 101. This is because the range in which the mounting bracket 90 can be installed is restricted in the longitudinal direction of the guide rail 80. However, which region in the longitudinal direction of the guide rail 80 where the mounting member corresponding to the mounting bracket 90 is provided can be appropriately selected according to the configuration of the vehicle door. For example, it is possible to use a mounting bracket having a length extending to the inside of the door below the upright sash 101. In the illustrated embodiment, the guide rail 80 is fixed to the inner panel 100 even in a region below the mounting bracket 90 by using a mounting member other than the mounting bracket 90.

The supporting

legs

85 and 86 in the illustrated form include a type having one

fastening portion

85b and 86b and a type having a pair of upper and

lower fastening portions

85b and 86b. The number and arrangement of the contact points (the positions corresponding to the

fastening portions

85b and 86b) of the

individual support legs

85 and 86 with respect to the mounting bracket 90 can be set arbitrarily, and are not limited to the illustrated form. As an example, the guide rail 80 has a rail fixing portion fixed to the inner surface of the vehicle interior side wall 80a and portions corresponding to the

fastening portions

85b and 86b, and extends in the width direction of the guide rail 80. It is also possible to use support legs.

Further, the guide rail is directly in contact with and fixed to the mounting member (a member corresponding to the mounting bracket 90) without interposing an intermediate member such as the supporting

legs

85 and 86 in the illustrated form. It is also possible to select.

The embodiment of the present invention is not limited to the above-described embodiment and its modified examples, and may be variously changed, replaced and modified without departing from the spirit of the technical idea of the present invention. Furthermore, if the technical idea of the present invention can be realized in another way by the advancement of the technology or another derivative technology, the method may be implemented. Therefore, the claims cover all embodiments that may be included in the scope of the technical idea of the present invention.

According to the present invention, complicated assembling work is unnecessary, and the opening / closing body can be driven without requiring a special configuration, which is particularly useful for a vehicle door assembly.
