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 water stop ribs 32i that protrude to the outside of the vehicle. The water stop ribs 32 i are continuously formed in the longitudinal direction (vertical direction) of the upright pillar sash 15.

  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 position of the garnish 32 in the vehicle inside / outside direction can be determined by the contact of the surface facing the vehicle inner side of the appearance portion 32a with the surface facing the vehicle inner side of the design portion 30b of the inner sash 30. As a different configuration, the position of the garnish 32 in the vehicle interior / exterior direction is determined such that the surface facing the vehicle inner side of the fitting step portion 32g contacts the end surface of the positioning portion 31e (the surface facing the vehicle outer side). You can also. In any case, it is preferable that a portion other than the portion set as the position for positioning in the vehicle interior / exterior direction is designed to have a clearance in the vehicle interior / exterior direction so as not to disturb the positioning.

  Further, as a different configuration, positioning of the garnish 32 in the vehicle front-rear direction (inner and outer peripheral directions of the door frame 12) is performed between the design portion 30b and the appearance portion 32a, and positioning of the garnish 32 in the interior and exterior directions of the vehicle is performed. It is also possible to carry out at the vehicle interior side (positioning part 31e etc.) other than 30b.

  That is, the positioning of the garnish 32 in all directions is not performed by the design portion 30b and the appearance portion 32a, but the positioning of the garnish 32 in at least one direction is located on the vehicle inner side than the design portion 30b and the appearance portion 32a. What is necessary is just to satisfy | fill the requirements of performing by site | part (positioning part 31e, the fitting step part 32g, etc.).

  With the garnish 32 positioned as described above, 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 narrows the distance from the edge surface W3 of the window glass W.

  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 for accommodating the elastic cover 33 is formed between the window glass W and the garnish 32. This space includes the first space U1 defined by the front projecting portion 32d and the first holding portion 32e of the garnish 32 and the edge surface W3 of the window glass W, and the interior of the second holding portion 32f of the garnish 32 and the window glass W. It consists of a second space U2 between the side surface W2.

  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 includes a hollow portion 33a having a hollow cross-sectional shape and a cantilevered lip portion 33b protruding forward from the hollow portion 33a.

  The hollow portion 33a of the elastic cover 33 is disposed along the first space U1. The position of the elastic cover 33 in the vehicle front-rear direction is determined by a part of the hollow portion 33a coming into contact with the positioning surface 32h of the garnish 32 facing in the first space U1. Further, the surface of the hollow portion 33a facing the vehicle inner side comes into contact with the water stop rib 32i provided on the first holding portion 32e of the garnish 32, so that the position of the hollow portion 33a in the vehicle inside / outside direction is determined. A lateral recess 33c is formed on the rear side of the hollow portion 33a. The side recess 33c has a shape into which the front protrusion 32d of the garnish 32 fits.

  The lip portion 33b of the elastic cover 33 is disposed along the second space U2. The inner surface of the lip portion 33b is held by the second holding portion 32f. The tip of the lip portion 33b is in contact with a part of the slider 20 accommodated in the guide rail 31 (first section 31f).

  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 hollow portion 33a is sandwiched between the edge surface W3 of the window glass W and the front projecting portion 32d of the garnish 32, and seals the space therebetween. 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 tightly seals between these. In addition, a space between the water stopping ribs 32 i provided on the garnish 32 and the hollow portion 33 a is also sealed watertight. Thereby, the sealing performance in the state which closed the window glass W is ensured.

  The elastic cover 33 is also disposed adjacent to the garnish 32 so that, like the garnish 32, a part of the door frame 12 disposed 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 this embodiment, the garnish 32 that is an exterior member is added to the portion (the outer appearance portion 32a) that covers the design portion 30b of the inner sash 30, and the front (inner circumference) Side) and a portion extending to the vehicle interior side (extension holding portion 32c). The garnish 32 is positioned by bringing an extension holding portion 32c (fitting step portion 32g), which is an extension of the garnish 32, into contact with the guide rail 31 (positioning portion 31e). The guide rail 31 has a closed cross-section by being fitted inside the open portion of the bag-like portion 30a of the inner sash 30 on the outer side of the vehicle, and the inner side of the vertical column sash 15 together with the bag-like portion 30a and the connecting portion 30c. It is composed. That is, positioning of the garnish 32 is performed at a place other than the design portion 30b that overlaps the exterior portion 32a in the vehicle interior and exterior direction (the vehicle interior portion that does not overlap the exterior portion 32a and the interior and exterior directions).

  According to this door frame structure, the support of the garnish 32 with respect to the design part 30b of the inner sash 30 can be simplified. For example, as a comparative example with the present embodiment, a structure is known in which a protrusion provided on the garnish 32 is inserted into a hole provided on the design portion 30b and fastened while positioning. That is, it is a structure which positions and fixes the garnish 32 in all directions with respect to the design portion 30b. In this comparative example, since the fastening part with the garnish 32 is exposed on the inner side of the design part 30b, it is necessary to separately cover the fastening part with a cover member or the like so as to hide the fastening part.

  On the other hand, in this embodiment, the positioning of the garnish 32 in at least the vehicle front-rear direction (inner and outer peripheral directions of the door frame 12) is performed by the positioning portion 31e and the fitting step portion 32g located on the vehicle inner side. It is not necessary to provide a complicated and time-consuming structure as in the comparative example between the design portion 30b and the appearance portion 32a. Specifically, a minimum amount of fixing (double-sided tape, adhesive, fitting with the rear edge portion 32b, etc.) may be performed so that the appearance portion 32a of the garnish 32 does not float from the design portion 30b. The fastening structure of the garnish 32 can be prevented from being exposed on the inner surface (see FIG. 2). Therefore, the aesthetic appearance can be ensured easily and reliably on the inner surface of the design portion 30b. For example, a simple coating or film sticking may be performed without attaching a large cover member to the inner surface of the design portion 30b. Therefore, the shape of the vehicle interior of the upright pillar sash 15 and the degree of freedom in design are improved.

  Further, the positioning portion 31e with which the garnish 32 abuts is a portion where the bag-shaped portion 30a and the guide rail 31 form a cylindrical portion with a closed cross section, and the vertical pillar sash 15 has a high cross-sectional strength. Yes. Therefore, positioning of the garnish 32 using the positioning portion 31e is excellent in terms of support strength and stability.

  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.

  Further, as an advantage of positioning the garnish 32 by the guide rail 31, there is a point that it is easy to improve the flushness of the window 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.

  The extension holding part 32 c of the garnish 32 functions as a part that receives positioning by the guide rail 31 and also as a part that holds the elastic cover 33. The garnish 32 is manufactured as a molded product of synthetic resin, and has high processing accuracy at the time of manufacturing, and therefore, the accuracy of each part that holds the elastic cover 33 is excellent.

  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 garnish 32 has a simple cross-sectional shape as compared with the inner sash 30 and the guide rail 31, and can be easily manufactured by molding, and accuracy control is also easy. Therefore, when the elastic cover 33 is held by the garnish 32, the positional accuracy of the elastic cover 33 is easily improved.
