The inner sash 30 and the guide rail 31 can be formed of a non-metallic material such as synthetic resin. Each of the inner sash 30, the guide rail 31, and the garnish 32 is a long member that extends along the longitudinal direction (vertical direction) of the upright pillar sash 15.

  The door 10 of the present embodiment has a so-called flash surface structure in which the vehicle outer side surface W1 of the window glass W and the vehicle outer side surface 32j of the garnish 32 are arranged in a positional relationship that is substantially flush with each other. Further, the edge surface W3 of the window glass W is in contact with the garnish 32 without any other member interposed therebetween. An elastic cover 33 is disposed as a seal member on the vehicle interior side where the wind glass W and the garnish 32 are in contact. That is, the elastic cover 33 is not sandwiched between the window glass W and the garnish 32 in the vehicle front-rear direction (inner and outer peripheral directions) (the elastic cover 33 is not exposed to the outer surface), and the window glass W is waterproofed by the elastic cover 33 inside the vehicle. In this configuration, the appearance quality of the door 10 is improved while obtaining a predetermined water tightness.

  The inner sash 30 includes a bag-like portion 30a located on the inner side of the vehicle, a design portion 30b located on the outer side of the vehicle, and a connection portion 30c that connects the bag-like portion 30a and the design portion 30b. The bag-like portion 30a has a concave cross-sectional shape that opens toward the vehicle exterior side. The connecting portion 30c includes a rear extending portion 30e extending rearward from an end portion (a vehicle outer end portion) of the rear side wall portion 30d of the bag-shaped portion 30a, and an end portion (rear side end) of the rear extending portion 30e. A vehicle exterior extending portion 30f extending outward from the vehicle. The design portion 30b extends rearward from an end portion (end portion on the vehicle outer side) of the vehicle outer extension portion 30f in the connection portion 30c.

  In the vehicle front-rear direction, the edge surface W3 on the rear edge side of the window glass W is located behind the rear side wall portion 30d of the inner sash 30 and ahead of the vehicle outer extension portion 30f. Further, in the vehicle interior / exterior direction, the vehicle interior side surface W2 of the window glass W and the interior surface of the design portion 30b of the inner sash 30 are substantially at the same position. That is, when the window glass W is used as a reference, the entire bag-like portion 30a of the inner sash 30 and a part of the front side of the connecting portion 30c are located on the vehicle inner side of the window glass W. Further, the entire design portion 30b and a part on the rear side of the connection portion 30c are located behind the window glass W without overlapping the window glass W in the vehicle interior / exterior direction.

  The guide rail 31 has a concave cross-sectional shape opened toward the vehicle outer side, a base portion 31a extending in the vehicle front-rear direction, a front wall portion 31b extending from the base portion 31a in the vehicle outer direction, and a rear wall portion 31c.

The partition wall portion 31d extends from the base portion 31a in the vehicle exterior direction, and a bent portion that bends forward is provided at an end portion of the partition wall portion 31d on the vehicle exterior side.

  The guide rail 31 is disposed so as to be fitted inside the open portion of the inner side of the bag-like portion 30a of the inner sash 30, and the front wall portion 31b and the rear wall portion 31c are arranged in the vehicle front-rear direction by the bag-like portion 30a. It is sandwiched. A part of the guide rail 31 protrudes outside the bag-shaped portion 30a in a state of being fitted to the bag-shaped portion 30a. In particular, a part of the rear wall portion 31c of the guide rail 31 protrudes beyond the end portion of the rear side wall portion 30d (the end portion on the vehicle outer side connected to the rearward extending portion 30e) to constitute the positioning portion 31e. . A region defined by the positioning portion 31e and the connecting portion 30c of the inner sash 30 is a concave portion T.

  The window glass W is supported and guided by the guide rail 31 so as to be movable up and down. That is, the guide rail 31 constitutes a main body portion of the upright pillar sash 15 together with the inner sash 30 and also functions as a member for supporting and guiding the window glass W in the window regulator 18.

  The shoe base 21 of the slider 20 included in the window regulator 18 is bonded and fixed to a part of the vehicle inner side surface W2 of the window glass W (see FIGS. 2 and 3). The slider 20 includes a shoe base 21 and a shoe 22. As shown in FIG. 1, two sliders 20 are provided that are spaced apart in the vertical direction.

  The space in the guide rail 31 is partitioned into a first partition 31f and a second partition 31g in the front-rear direction by a partition wall portion 31d. The shoe 22 of the slider 20 is accommodated in the first section 31f so as to be slidable in the vertical direction (the direction perpendicular to the paper surface shown in FIGS. 2 and 3). A wire end support portion 23 connected to the shoe base 21 of the slider 20 is accommodated in the second section 31g (see FIG. 3). A wire end (not shown) provided at the end of a wire 24 that drives the slider 20 is connected to the wire end support portion 23. Of the two sliders 20 shown in FIG. 1, only the upper slider 20 has the wire end support portion 23.

  As shown in FIG. 4, the wire 24 is routed along the longitudinal direction of the guide rail 31. A motor unit 25 is attached to the guide rail 31. The motor unit 25 includes a drum that is rotationally driven by the driving force of the motor 25a, and a pair of wires 24 are wound around the drum. One wire 24 shown in FIG. 4 extends upward from the drum along the vehicle inner side of the base portion 31a of the guide rail 31, and the vehicle outer side of the base portion 31a by the guide pulley 26 supported near the upper end of the guide rail 31 ( Guided to the second section 31g) and connected to the wire end support 23 from above. The other wire 24 extends upward from the drum along the vehicle outer side of the base portion 31a of the guide rail 31, and is connected to the wire end support portion 23 from below. The window regulator 18 pulls the slider 20 up and down to drive the window glass W up and down by controlling the winding or unwinding of each wire 24 by driving the motor 25a.

  Of the standing pillar sash 15, the inner sash 30 has a length from the door corner portion 17 to the vicinity of the upper edge of the door panel 11. On the other hand, since the guide rail 31 guides the slider 20 to the fully open position of the window glass W, it has a length inserted to the lower part of the door panel 11 (see FIG. 1).

  The garnish 32 is an exterior member that is attached to the vehicle exterior side of the main body portion of the upright column sash 15 including the inner sash 30 and the guide rail 31 and forms the appearance of the upright column sash 15. ).

  The garnish 32 has an appearance portion 32 a that covers the vehicle exterior side of the design portion 30 b of the inner sash 30. As shown in FIG. 2, the appearance portion 32 a has a width that covers the entire design portion 30 b in the vehicle front-rear direction. A rear edge 32b having a shape that curves (bends) toward the inner side of the vehicle and covers the end on the rear side of the design portion 30b is provided on the edge on the rear side (outer peripheral side) of the appearance portion 32a. .

  The garnish 32 further has an extended holding portion 32c extending from the vicinity of the front (inner peripheral side) end portion of the appearance portion 32a. The extended holding portion 32c includes a front protruding portion 32d having a shape in which the end portion of the external appearance portion 32a protrudes forward, and a bent first holding portion 32e extending to the front side after protruding from the front protruding portion 32d to the vehicle interior side. And a second holding part 32f extending further forward from the first holding part 32e. At the boundary portion between the first holding part 32e and the second holding part 32f, a fitting step part 32g facing the vehicle inner side and a positioning surface 32h facing the rear side (outer peripheral side) are formed. Further, the first holding portion 32e is provided with a water stop rib 32i that protrudes outward from the vehicle and faces the vehicle inner side surface W2 of the window glass W. The water stop ribs 32 i are continuously formed in the longitudinal direction (vertical direction) of the upright pillar sash 15.

  Of the garnish 32, the appearance portion 32 a, the design portion 30 b and the front projecting portion 32 d located on both edges thereof are portions that appear in the appearance of the upright pillar sash 15. As shown in FIGS. 2 and 3, the front protrusion 32d is thicker in the vehicle interior / exterior direction than the external appearance 32a. The thickness of the front protrusion 32d is substantially equal to the thickness of the window glass W (the distance between the vehicle outer side surface W1 and the vehicle inner side surface W2).

  The appearance portion 32a has a vehicle outer side surface 32j facing the vehicle outer side. The front protrusion 32d has an edge surface 32k facing the front side. The vehicle outer surface 32j continues to the front protruding portion 32d, and a chamfered portion 32m that smoothly curves from the vehicle outer surface 32j to the edge surface 32k is formed at a corner portion on the vehicle outer side of the front protruding portion 32d.

  The position of the garnish 32 is determined by bringing the fitting step 32 g into contact with the positioning portion 31 e of the guide rail 31. More specifically, the fitting step 32g has an angular shape including a surface facing the front side and a surface facing the vehicle interior. The front facing surface of the fitting step 32g contacts the side surface (rear facing surface) of the positioning portion 31e, thereby determining the position of the garnish 32 in the vehicle front-rear direction (inner and outer peripheral directions of the door frame 12). . The surface facing the vehicle inner side of the fitting step portion 32g contacts the end surface (surface facing the vehicle outer side) of the positioning portion 31e, and the position of the garnish 32 in the vehicle interior / exterior direction can also be determined by this contact.

  In the state where the garnish 32 is positioned in this manner, the appearance portion 32a covers the vehicle exterior side of the design portion 30b of the inner sash 30, and the rear edge portion 32b covers the end portion on the rear side of the design portion 30b. Of the extended holding portion 32c, the front protruding portion 32d protrudes more forward than the design portion 30b, and the edge surface 32k is in contact with the edge surface W3 of the window glass W. The vehicle outer side surface 32j of the garnish 32 and the vehicle outer side surface W1 of the window glass W are continuous in the vehicle front-rear direction in a substantially flush relationship.

  The first holding part 32e of the extension holding part 32c is accommodated in a recess T defined by the connection part 30c of the inner sash 30 and the positioning part 31e of the guide rail 31. That is, the first holding part 32e is supported along the inner surface of the concave connection part 30c. The second holding portion 32 f protrudes forward from the recess T and is located on the vehicle outer side of the second section 31 g of the guide rail 31. Accordingly, the extension holding portion 32c of the garnish 32 covers the connection portion 30c of the inner sash 30 and a part of the guide rail 31 (such as the rear wall portion 31c) to prevent the garnish 32 from being seen from the outside of the vehicle.

  The garnish 32 whose position is determined as described above is fixed to the combined body of the inner sash 30 and the guide rail 31. When fixing the garnish 32, arbitrary means, such as an adhesive agent and a double-sided tape, can be used. Here, since the garnish 32 is positioned via the positioning portion 31e, no strict positioning means is required between the design portion 30b and the appearance portion 32a.

  A space U for accommodating the elastic cover 33 is formed between the wind glass W and the garnish 32. The space U is covered with the vehicle inner side surface W2 of the window glass W and the front protruding portion 32d of the garnish 32, and the vehicle inner side is covered with the first holding portion 32e and the second holding portion 32f of the garnish 32. Moreover, the rear side of the space U is closed by the first holding part 32e, and the front side of the space U is opened.

  The elastic cover 33 is made of an elastic body, and is held by the garnish 32 and extends in the longitudinal direction of the upright pillar sash 15. The elastic cover 33 has a base portion 33a and a cantilevered lip portion 33b protruding forward from the base portion 33a. The base portion 33a has a solid shape that is thicker in the vehicle interior / exterior direction than the lip portion 33b, and is provided with a side convex portion 33c that protrudes toward the rear side opposite to the lip portion 33b.

  The base portion 33a of the elastic cover 33 is held by the first holding portion 32e and the front protruding portion 32d of the garnish 32. The position of the elastic cover 33 in the vehicle front-rear direction is determined by a part of the base portion 33a coming into contact with the positioning surface 32h of the garnish 32. A surface of the base portion 33a facing the vehicle inner side comes into contact with a water stop rib 32i provided on the first holding portion 32e of the garnish 32, so that the position of the base portion 33a in the in-vehicle direction is determined. Further, the side cover 33c enters the inside of the front projecting portion 32d so that the elastic cover to the outside of the vehicle can be obtained even when the window glass W is opened (the pressing from the outside of the vehicle by the inside surface W2 is released). Prevents 33 from falling off.

  The lip portion 33 b of the elastic cover 33 is held along the second holding portion 32 f of the garnish 32. The inner surface of the lip portion 33b is in close contact with the second holding portion 32f. The tip of the lip portion 33b is in contact with a part of the slider 20 in which the shoe 22 is accommodated in the guide rail 31 (first section 31f). Note that the lip portion 33 b may not be in contact with the slider 20.

  The elastic cover 33 comes into contact with the window glass W while being elastically deformed, and waterproofs between the window glass W and the garnish 32. The base portion 33a is sandwiched between the vehicle interior side surface W2 of the window glass W and the water stop ribs 32i of the garnish 32 and is compressed in the vehicle interior / exterior direction.

  Water that has entered the space U from the space between the edge surface W3 of the window glass W and the edge surface 32k of the front projecting portion 32d and has traveled along the first holding portion 32e has the water stop rib 32i formed on the base portion 33a of the elastic cover 33. Water is stopped at the point where it abuts. Further, the water that enters from between the edge surface W3 and the edge surface 32k and tries to advance along the vehicle inner side surface W2 of the window glass W is stopped at the location where the base 33a is in close contact with the vehicle inner side surface W2. Further, the lip portion 33b is sandwiched between the vehicle inner side surface W2 of the window glass W and the second holding portion 32f of the garnish 32, and is water that tends to go further to the back side (front side) of the space U than the base portion 33a. Stop water. Thereby, the watertightness inside a space U in the state which closed the window glass W is ensured.

  The elastic cover 33 is also held by the extension holding portion 32c of the garnish 32, so that, like the garnish 32, a part of the door frame 12 arranged on the vehicle inner side is prevented from being visually recognized from the vehicle outer side. . The elastic cover 33 covers the extended holding portion 32c of the garnish 32 from the outside, and further extends forward longer than the second holding portion 32f of the extended holding portion 32c, so that the entire second section 31g of the guide rail 31 and the first section are extended. A part of 31f is prevented from being visually recognized from the outside of the vehicle.

  As described above, in the upright pillar sash 15 constituting the door 10 of the present embodiment, the edge surface 32k of the front projecting portion 32d of the garnish 32 as an exterior member and the edge surface W3 of the window glass W are separate members. The vehicle is adjacent to the vehicle front-rear direction (inner and outer peripheral directions) without sandwiching the vehicle. Accordingly, when the door 10 is viewed from the outside of the vehicle as shown in FIG. 1, only one parting line extending along the edge surface W3 of the window glass W and the edge surface 32k of the garnish 32 extends in the vertical pillar sash 15 portion. There are few parting lines compared to existing vehicle doors, and the structure is excellent in aesthetics.

  In the door frame, generally, an elastic body called a glass run or the like is arranged at a position in sliding contact with the window glass. Such an elastic body has functions such as ensuring waterproofness at the peripheral edge of the window glass and preventing abnormal noise and vibration during operation when the window glass opens and closes the window opening and in a closed state. . In the upright pillar sash 15 in the door frame 12 of the present embodiment, the elastic cover 33 in contact with the vehicle interior side surface W2 of the window glass W has these functions. On the other hand, the garnish 32 is in contact with the edge surface W3 of the window glass W without sandwiching the elastic cover 33 therebetween. And the edge surface 32k of the garnish 32 which faces the edge surface W3 of the window glass W is a resistance reduction part which reduces the sliding resistance at the time of raising / lowering of the window glass W. As shown in FIG.

  Specifically, a coating made of a material having a lower frictional resistance than the main body portion of the garnish 32 can be applied to the surface of the edge surface 32k. Alternatively, the garnish 32 may be molded with a plurality of materials (so-called multicolor molding), and a low friction material may be used at a portion where the edge surface 32k is formed. With such a configuration, in the door frame 12 having a structure in which the window glass W and the garnish 32 are in direct contact with each other, the slidability when the window glass W is raised and lowered is improved.

  The front protruding portion 32d of the garnish 32 is thicker than the external appearance portion 32a, and the width of the edge surface 32k in the vehicle interior / exterior direction is secured wide. As a result, the edge surface 32k of the garnish 32 and the edge surface W3 of the window glass W can be easily opposed to each other with high accuracy, and it is difficult for water to enter the space U from the space between the edge surface 32k and the edge surface W3 to the inside of the vehicle. It has become. Although the waterproof property is ensured by the elastic cover 33 in the space U, the waterproof performance can be further improved if there is little water intrusion into the space U.

  As shown in FIGS. 2 and 3, since the vehicle outer surface W1 and the vehicle outer surface 32j are continuous in a substantially flush relationship, there is almost no unevenness in the vehicle interior / exterior direction from the window glass W to the garnish 32. An outer surface is formed.

  The chamfered portion 32m of the garnish 32 prevents the corner portion between the vehicle outer side surface 32j and the edge surface 32k from protruding forward and interferes with the window glass W, and allows the edge surface 32k to be accurately managed so as to be a parting line. It has a function. In addition, the smooth shape of the chamfered portion 32m itself can also improve the appearance quality of the portion along the parting line.

  The position of the garnish 32 is determined by bringing the extension holding portion 32c (fitting step portion 32g) into contact with the guide rail 31 (positioning portion 31e). An advantage of this configuration is that it is easy to improve the flushness of the wind glass W and the garnish 32 in the flash surface structure. Since the guide rail 31 supports the window glass W via the slider 20, the positional accuracy of the vehicle outer side surface W <b> 1 of the window glass W is determined based on the guide rail 31. Here, if the garnish 32 is positioned so that the guide rail 31 becomes a reference as in the present embodiment, the window glass W and the garnish 32 share the position reference member (the guide rail 31). Therefore, it is easy to improve the positional accuracy of each other.

  Further, the guide rail 31 is fitted inside the open portion of the inner side of the bag-like portion 30a of the inner sash 30 to constitute the inner side portion of the upright pillar sash 15 together with the bag-like portion 30a. The inner side portion of the vehicle forms a cylindrical section with a closed cross-section by the bag-shaped portion 30 a and the guide rail 31, and is a portion having a high cross-sectional strength in the upright pillar sash 15. Therefore, positioning the garnish 32 using the positioning portion 31e is particularly excellent in terms of support strength and stability.

  Moreover, in the door 10 of this embodiment, the place which should consider the invasion of the water from the outside in the vertical pillar sash 15 is between the wind glass W and the garnish 32. If the number of parting lines is reduced, the number of parts that appear on the outer surface of the door 10 and require water stop is reduced, so that the waterproof structure can be simplified and high water tightness can be easily obtained. And it is possible to obtain sufficient water tightness by the small and simple elastic cover 33 disposed inside the windshield W.

  Furthermore, since the elastic cover 33 is held by the garnish 32 itself, which is a portion to be waterproofed, the positional accuracy of the elastic cover 33 with respect to the waterproof portion can be easily managed. For example, it is easy to set the contact state of the water stop rib 32i with respect to the elastic cover 33 and to manage the accuracy. Further, since the elastic cover 33 is held only by the garnish 32 without straddling a plurality of members, there is an advantage that it is not affected by variations in accuracy among components.

  The garnish 32 is manufactured as a molded product of synthetic resin, and has high processing accuracy at the time of manufacturing, and thus has excellent holding accuracy with respect to the elastic cover 33. For example, the inner sash 30 and the guide rail 31 are long metal members, and have a shape that is greatly curved in the vehicle interior and exterior directions according to the outer surface shape of the door 10 (see the guide rail 31 in FIG. 4). ). In the case where such a long member having a complicated shape is formed of metal, it is common to perform a bending process after forming a linear basic shape by extrusion molding or the like. Then, a very high technique is required for managing the surface accuracy of each part. On the other hand, the manufacturing process of the garnish 32 is simpler than that of the inner sash 30 and the guide rail 31 (for example, it can be formed by injection molding), and accuracy control is easy. For this reason, when the elastic cover 33 is held by the garnish 32, the surface pressure of the contact portion of the garnish 32 with the elastic cover 33 is unlikely to vary, and as a result, the waterproof property around the window glass W by the elastic cover 33 is improved.

  The elastic cover 33 comes into contact with the positioning surface 32h and is in a stable holding state in which it does not drop off from the garnish 32 by inserting the side protrusion 33c into the vehicle interior of the front protrusion 32d. Therefore, the sub-assembly of the elastic cover 33 and the garnish 32 is possible. Since it is only necessary to assemble the garnish 32 with the elastic cover 33 attached to the inner sash 30 and the guide rail 31, the assembly process can be reduced and the productivity of the door frame 12 is improved.

  The guide rail 31 has a function of supporting and guiding the slider 20 in the window regulator 18. In addition to this, by positioning the garnish 32, the guide rail 31 can be provided with a composite function, and a door frame structure having a reduced number of parts while being multi-functional can be obtained.

  The door frame structure in the present invention is not limited to the above embodiment. For example, the upright pillar sash 15 can be configured as in the modifications shown in FIGS. In these modified examples, portions common to the above embodiment are denoted by common reference numerals and description thereof is omitted.

  In the first modification of the upright pillar sash 15 shown in FIG. 5, the garnish 32 is provided with a small protrusion 32 n that protrudes further forward from the front protrusion 32 d. The small protrusion 32n is a protrusion having a semicircular cross section having a diameter smaller than the thickness of the front protrusion 32d in the vehicle interior / exit direction, and is formed continuously in the longitudinal direction (vertical direction) of the garnish 32. .

  Since the top of the small protrusion 32n is opposed to the edge surface W3 of the window glass W in a linear region, the structure in which the edge surface 32k of the front protrusion 32d is opposed to the edge surface W3 of the window glass W (FIG. 2, Compared with FIG. 3), the effect of reducing the sliding resistance in the garnish 32 when contacting the edge surface W3 of the window glass W is obtained. That is, the small protrusion 32n functions as a resistance reducing unit that reduces sliding resistance when the window glass W is raised and lowered. In order to further reduce the sliding resistance, a coating for reducing friction is applied to the outer surface of the small protrusion 32n, or the small protrusion 32n is formed of a material having lower friction than the other parts of the garnish 32. You can also

  In the second modified example of the upright pillar sash 15 shown in FIG. 6, the garnish 32 is not provided with the front projecting portion 32d, and is simply bent inward from the exterior portion 32a to the first holding portion 32e of the extension holding portion 32c. It becomes the shape to do. The edge surface 32p of the garnish 32 facing the edge surface W3 of the window glass W is formed as a resistance reducing portion that reduces the sliding resistance when the window glass W is raised and lowered, like the edge surface 32k of the above embodiment. Further, a smoothly chamfered portion 32q is formed at the boundary between the vehicle outer surface 32j and the edge surface 32p.

  In the configuration of FIG. 6, the garnish 32 is not provided with a portion (front protrusion 32 d) that restricts the movement of the elastic cover 33 toward the vehicle outer side with respect to the side protrusion 33 c. However, the elastic cover 33 is fixed to the extended holding portion 32c of the garnish 32 by using a predetermined fixing means (tape, adhesive, etc.), so that the elastic cover to the outside of the vehicle can be obtained even when the window glass W is opened. 33 can be prevented from falling off.

  The third modified example of the upright pillar sash 15 shown in FIG. 7 is obtained by changing the shape of the elastic cover 33, and the configuration other than the elastic cover 33 is common to the second modified example in FIG. The elastic cover 33 in FIG. 7 has a hollow structure in which a base portion 33a has an internal space 33d. The hollow base 33a is more flexible than the solid structure and easily elastically deforms. Therefore, the contact pressure with respect to the vehicle inner side surface W2 when the window glass W moves up and down can be reduced, and the sliding resistance of the window glass W by the elastic cover 33 can be reduced. Even if the accuracy error between the wind glass W and the extended holding portion 32c of the garnish 32 is large to some extent, the base portion 33a having a hollow structure can easily maintain the waterproof performance by absorbing the error by elastic deformation.

  The base 33a of the elastic cover 33 in FIG. 7 has a hollow structure in which the internal space 33d has a closed cross section, but the elastic cover 33 can also be configured as a hollow structure with a non-closed cross section that partially opens. .

  In the standing pillar sash 15 of the fourth modified example shown in FIG. 8, a portion corresponding to the bag-shaped portion 30 a of the inner sash 30 of the above embodiment is formed integrally with the garnish 32. Parts corresponding to the design portion 30b and the connection portion 30c of the inner sash 30 are not provided. The configuration of the garnish 32 from the appearance part 32a to the extension holding part 32c is common to the second modification example shown in FIG. 6 and the third modification example shown in FIG.

  The garnish 32 shown in FIG. 8 further has a bag-like portion 32r that protrudes from the vicinity of the boundary between the first holding portion 32e and the second holding portion 32f in the extended holding portion 32c toward the inside of the vehicle. The shape of the bag-like portion 32r is substantially the same as the bag-like portion 30a in the inner sash 30 of the above-described embodiment, and has a bag-like cross-sectional shape that is open toward the vehicle exterior. And the guide rail 31 is arrange | positioned so that the inside of the open part of the vehicle outer side in the bag-like part 32r of the garnish 32 may be fitted.

  That is, in the 4th modification shown in FIG. 8, the guide rail 31 comprises the sash member (vehicle inside part) located in the vehicle inside of the window glass W. As shown in FIG. The positioning of the garnish 32 by the positioning portion 31e of the guide rail 31 is common to the above-described embodiment (FIGS. 2 and 3) and the first to third modifications (FIGS. 5 to 7). ing. The point that the edge surface 32p of the garnish 32 faces the edge surface W3 of the window glass W is common to the second modification (FIG. 6) and the third modification (FIG. 7).

  In the above embodiment and the first to fourth modifications, the guide rail 31 includes the positioning portion 31e that determines the position of the garnish 32. However, it is possible to provide a similar positioning portion on the inner sash 30. . In this case, it is also possible to provide a positioning part in the connection part 30c instead of the bag-like part 30a.

Similarly to the relationship between the window glass W and the garnish 32 in the above embodiment, the edge surface 42f of the front protrusion 42c of the garnish 42 that is an exterior member and the edge surface W3 of the window glass W do not sandwich another member therebetween. Adjacent to the vehicle longitudinal direction (inner and outer circumferential directions). Therefore, only one parting line along the edge surface W3 of the window glass W and the edge surface 42f of the garnish 42 exists at the portion along the vertical pillar sash 15, and the structure is excellent in aesthetic appearance.

  The edge surface 42f of the garnish 42 facing the edge surface W3 of the window glass W is a resistance reducing portion that reduces the sliding resistance when the window glass W is raised and lowered. Specifically, a coating made of a low friction material is applied to the surface of the edge surface 42f, or the garnish 42 is molded with a plurality of materials (multicolor molding), and the portion where the edge surface 42f is formed has a low friction property. The material can be used. With such a configuration, the slidability when the window glass W is raised and lowered is improved.

  The means for fixing the garnish 42 to the inner sash 40 is not limited to fixing with screws such as the fastening members 45 and 46. In the configuration shown in FIG. 9, since the holding portion positioned on the vehicle outer side of the support portion 42q holds the elastic cover 43, a fastening means cannot be provided on the vehicle outer side of the support portion 42q. In addition, since the vehicle outer surface of the support portion 42r is visually recognized from the vehicle outer side through the window glass W, it is also aesthetically difficult to provide a fastening means on the vehicle outer side of the support portion 42r. Because of such conditions, fastening members 45 and 46 of a type that are screwed into the support portions 42q and 42r from the inside of the vehicle are used. However, when fastening means can be arranged on the vehicle exterior side of the support portions 42q and 42r, a fastening member of a type screwed from the vehicle exterior side, or the support portion 42q (support portion 42r) and the rear extension portion 40e (frontward) It is also possible to use a type of fastening member that penetrates the extended portion 40h in the vehicle interior / exit direction and caulks both ends.

  In the configuration shown in FIG. 9, the guide part 42h of the garnish 42 holds the components of the window regulator. Therefore, by assembling the components of the window regulator to the garnish 42 in advance and then assembling the garnish 42 to the inner sash 40, the assembling workability of the upright pillar sash 15 is improved.

  The standing pillar sash 15 of the sixth modification shown in FIG. 10 is obtained by changing a part of the fifth modification shown in FIG. The inner sash 40 of FIG. 10 does not have a portion corresponding to the design portion 40 b shown in FIG. 9, and the end of the vehicle outer extension portion 40 f is one terminal of the inner sash 40. Other configurations are the same as those in FIG. 9, and the configurations and arrangement of the garnish 42 and the wind glass W are as described above.

  As can be seen from the above-described embodiments (FIGS. 1 to 4) and the modifications (FIGS. 5 to 10), the present invention provides an edge surface W3 of the window glass W and an edge of the garnish 32 (42) as an exterior member. It is only necessary to satisfy the requirement that the portions face each other in the inner and outer circumferential directions (vehicle longitudinal direction), and the configuration of the portion of the upright pillar sash 15 located on the vehicle inner side of the window glass W can be arbitrarily selected. is there.

It is also possible to adopt a configuration in which the edges of the garnishes 32 and 42 are not in contact with W3 and are separated. That is, any configuration may be used as long as the edge portions of the garnishes 32 and 42 are in contact with the edge surface W3 of the window glass W or not. Even when there is a gap between the edge surface W3 of the window glass W and the garnishes 32 and 42, the elastic cover 33 (43) positioned on the vehicle inner side of the gap can prevent water from entering the vehicle inner side.

  In the above embodiment and each modification, the part where the edge surfaces 32k, 32p, 42f of the garnishes 32, 42 and the small protrusion 32n are in contact with the edge surface W3 of the window glass W is a parting line visually recognized from the outside of the vehicle. It has become. As a modification, it is also possible to provide the garnishes 32 and 42 with vehicle-side extension portions (not shown) located outside the vehicle-side surface W1 of the window glass W. In this case, the vehicle outer side extensions of the garnishes 32 and 42 partially cover the vehicle outer side surface W1 of the window glass W from the vehicle outer side. And the edge part of the vehicle outer side extension part of the garnishes 32 and 42 becomes a parting line visually recognized from the vehicle outer side. Although the position of the parting line is different from that of the above embodiment (the modified example is closer to the inner periphery), it is common in that the number of parting lines is one.

  Further, in the above-described embodiment and each modification, the window regulator 18 is incorporated in the upright column sash 15, and the guide rail 31 constituting the upright column sash 15 and the guide portion 42 h of the garnish 42 support the components of the window regulator 18. However, it is also possible to apply the present invention to a door frame in which a window regulator component is not incorporated in a vertical pole sash.

  Further, the window regulator incorporated in the upright pillar sash 15 is not limited to the wire drive type as in the above-described embodiments and modifications, and other drive types (for example, rack and pinion) can be used.

  Although the said embodiment is applied to the door 10 of the right front part of a vehicle, the application to doors other than this is also possible.
