The rear end portion of the upper sash 15 and the upper end portion of the upright column sash 16 are joined at the door corner portion, and the upper end of the lower sash 17 is connected to the middle of the upper sash 15. The front and rear edges of the door glass 14 are held by the lower sash 17 and the vertical pillar sash 16, and the door glass 14 can be moved up and down along the lower sash 17 and the vertical pillar sash 16. When the door glass reaches the uppermost position in the window opening 13, the upper edge of the door glass is held by the upper sash 15.

  Hereinafter, a plurality of embodiments in which the present invention is applied to the upper sash 15 will be described. In the following embodiments, parts using the same reference numerals have a common configuration, and redundant description is omitted.

  The upper sash 15A of the first embodiment shown in FIG. 2 is configured by combining a frame main body 20 formed as an extruded product made of aluminum and a molding 30 which is an appearance member attached to the frame main body 20. Yes. The molding 30 is formed of an arbitrary material such as metal or synthetic resin.

  The frame body 20 includes a vehicle inner frame portion 21 located on the vehicle inner side, a connection portion 22 extending from the vehicle inner frame portion 21 toward the vehicle outer side, and a design portion 23 connected to the vehicle outer side of the connection portion 22. have. The vehicle inner frame portion 21 has a cylindrical cross-sectional shape with a hollow inside. A holding step portion 24 is formed on the vehicle outer side surface of the vehicle inner frame portion 21. The design portion 23 has an outer peripheral protrusion 23a extending from the location where the connection portion 22 is connected toward the outer peripheral side, and an inner peripheral protrusion 23b extending from the location where the connection portion 22 is connected toward the inner peripheral side. . The inner peripheral protrusion 23b has a smaller thickness in the thickness direction of the door 10 (the direction connecting the vehicle outer side and the vehicle inner side) than the outer peripheral protrusion 23a. Further, the protruding amount from the connecting portion 22 (the protruding amount in the direction connecting the inner peripheral side and the outer peripheral side) is smaller in the inner peripheral protruding portion 23b than in the outer peripheral protruding portion 23a. A claw portion 25 that protrudes toward the vehicle inner side is formed on the outer peripheral protrusion 23a. Near the boundary between the vehicle inner side frame portion 21 and the connecting portion 22, a claw portion 26 that protrudes to the outer peripheral side and faces the claw portion 25 is formed.

  The molding 30 includes a fixed portion 30a extending along the inner peripheral surface of the connection portion 22 of the frame body 20, and an inner peripheral extending portion 30b extending by bending the vehicle outer end of the fixed portion 30a toward the inner peripheral side. An engagement step portion 30c bent to the vehicle outer side with respect to the inner peripheral extension portion 30b, an inner peripheral extension portion 30d extending further to the inner peripheral side following the engagement step portion 30c, and an inner peripheral extension portion 30d. An outer surface portion 30e extending toward the outer peripheral side by folding the peripheral end portion toward the vehicle outer side, an outer peripheral bending portion 30f obtained by bending the outer peripheral side end portion of the outer surface portion 30e toward the inner side of the vehicle, and an end portion of the outer peripheral bending portion 30f And an engaging protrusion 30g (outer peripheral side mounting portion). A bent portion 31 is formed between the fixed portion 30a and the inner peripheral extending portion 30b, and a folded portion 32 is formed between the outer surface portion 30a and the inner peripheral extending portion 30d. In the mall 30, the inner peripheral extending portion 30b, the engagement step portion 30c, and the inner peripheral extending portion 30d constitute an inner peripheral extending portion that extends toward the inner peripheral side with respect to the fixed portion 30a.

  The molding 30 engages the engaging protrusion 30g with the outer peripheral protruding portion 23a, abuts the fixing portion 30a on the inner peripheral surface of the connecting portion 22 and fastens it with the rivet 40. Is attached to. The fixing portion 30a has a flat surface portion that is supported by being in surface contact with the connection portion 22 around a portion that is fastened and fixed by the rivet 40, and is fixed to the frame body 20 in a stable state. . In this attached state, the outer surface portion 30e of the molding 30 is positioned on the vehicle outer side of the design portion 23 of the frame body 20, the outer peripheral bending portion 30f faces the outer peripheral side end portion of the outer peripheral protrusion 23a of the design portion 23, and the inner peripheral extension The installation portion 30b is located along the inner surface of the inner peripheral protrusion 23b of the design portion 23. The molding 30 has a part of the outer surface portion 30a and an inner peripheral extending portion 30d projecting further to the inner peripheral side than the inner peripheral projecting portion 23b of the design portion 23 of the frame body 20, and the inner peripheral side of the inner peripheral projecting portion 23b. The inner peripheral side gap S1 formed between the end portion and the folded portion 32 is larger than the outer peripheral side gap formed between the outer peripheral end portion of the outer peripheral protruding portion 23a and the outer peripheral bent portion 30f.

  In a state where the frame body 20 and the molding 30 are combined, a glass holding portion 41 is formed on the inner peripheral side of the connection portion 22. The glass holding portion 41 is a groove-like portion that is open toward the inner peripheral side with the connection portion 22 as a bottom portion, and one (inner side) side wall is formed by the outer side surface of the inner side frame portion 21. The other side (the vehicle outer side) side wall of the glass holding part 41 has an inner peripheral extending part (from the bent part 31 to the folded part 32) of the molding 30 composed of the inner peripheral extending part 30b, the engaging step part 30c, and the inner peripheral extending part 30d. Region). A glass run (not shown) is inserted into the glass holding part 41. The glass run is formed of an elastically deformable material, has a substantially U-shaped cross-sectional shape opened toward the inner peripheral side, and is engaged with the engaging step portion 30c and the holding step portion 24 to form glass. It is held in the holding part 41. The edge part (upper edge part) of the door glass 14 that has entered the glass holding part 41 as shown in FIG. 2 is brought into contact with an elastically deformable contact part (not shown) provided in the glass run, and the vibration is suppressed. The

  A weather strip holding portion 42 is formed on the outer peripheral side of the connection portion 22 of the frame body 20. The weather strip holding portion 42 is a groove-like portion having the connecting portion 22 as a bottom portion and the outer peripheral protruding portion 23a and the base portion of the claw portion 26 as side walls on both sides. A weather strip base (not shown) is inserted into the weather strip holding portion 42 and is engaged with the claw portion 25 and the claw portion 26 to hold the weather strip. The weather strip is made of an elastically deformable material and abuts against the edge of the door opening of the vehicle body when the door 10 is closed with respect to the vehicle body, so that the space between the vehicle body and the door 10 is in a liquid-tight state. .

  In the upper sash 15A having the above configuration, the mounting portion of the molding 30 with respect to the frame main body 20 is an engaging protrusion 30g that engages with the fixing portion 30a along the connecting portion 22 and the outer peripheral protruding portion 23a of the design portion 23. There are few restrictions regarding the shape setting of the molding 30 between the fixed portion 30a and the engaging protrusion 30g. In particular, the frame body 20 is provided at a portion on the inner peripheral side of the connection portion 22 so that the protrusion amount from the connection portion 22 is smaller than the outer peripheral protrusion portion 23a and is thicker than the outer peripheral protrusion portion 23a. Therefore, the degree of freedom in setting the shape of the molding 30 on the inner peripheral side portion is higher than that of the connecting portion 22. For example, since the size of the gap S1 shown in FIG. 1 can be changed by setting the position of the folded portion 32 of the molding 30, the gap S1 is reduced within a range in which the holding width with respect to the door glass 14 is not insufficient, and the upper sash 15A It is possible to narrow the design portion (the width of the outer surface portion 30e of the molding 30).

  Moreover, since the design part 23 of the frame main body 20 does not exist in the area | region of the clearance gap S1, without receiving the restrictions of the design part 23, the space | interval of the inner peripheral extension part 30d and the outer surface part 30e of the molding 30 in the thickness direction of the door 10 is made. Can be set. Specifically, the inner peripheral extending portion 30d of the molding 30 constitutes a side wall on the vehicle outer side of the glass holding portion 41, and the inner peripheral extending portion 30d and the door are appropriately held in order to appropriately hold the door glass 14 by the glass run. The distance between the glasses 14 is determined. The inner surface extending portion 30d can be made closer to the outer surface portion 30e without being restricted by the design portion 23, and the step between the outer surface portion 30e and the door glass 14 can be reduced. Thereby, the freedom degree of design of upper sash 15A becomes high.

  The vehicle outside portion of the upper sash 15A is not only composed of the molding 30 but also includes the design portion 23 of the frame body 20, so that not only the design is excellent but also the strength is ensured. In particular, the inner peripheral protruding portion 23b protrudes on the inner peripheral side of the connecting portion 22, and the inner peripheral extending portion 30b can be supported by the inner peripheral protruding portion 23b while increasing the cross-sectional strength. It is possible to achieve both a high degree of freedom in shape and securing of strength at the inner peripheral side portion where the portion 41 is provided.

  Further, the bent portion 31 of the molding 30 abuts on the inner peripheral surface of the connection portion 22 of the frame body 20, thereby contributing to stable support of the molding 30. When the molding 30 is attached to the frame body 20, the engaging projection 30g is engaged with the outer peripheral projection 23a, and the molding 30 is rotated counterclockwise in FIG. It is preferable from the viewpoint of workability that the portion 30a is brought into contact with the connecting portion 22 and is finally fastened by the rivet 40. The contact of the bent portion 31 with the connection portion 22 restricts the rotation (falling) of the molding 30 in the direction opposite to that at the time of attachment, and the effect of stabilizing the molding 30 with respect to the frame body 20 is obtained.

  The upper sash 15B of the second embodiment shown in FIG. 3 has the same structure as the frame main body 20 of the first embodiment with respect to the frame main body 120, and is between the fixed portion 30a and the inner peripheral extending portion 30b of the molding 130. The point where the inclined portion 30h (gap forming portion) is formed is different from the molding 30 of the first embodiment. The inclined portion 30h has an inclination that advances from the vehicle inner side to the vehicle outer side as it advances from the outer peripheral side (fixed portion 30a) to the inner peripheral side (inner peripheral extending portion 30b). When attached to 120, a gap is formed between the corner portion that is the boundary between the inner peripheral protruding portion 23 b of the frame body 120 and the connecting portion 22 and the inclined portion 30 h of the molding 130. The bending portion 131 between the fixed portion 30a and the inclined portion 30h in the molding 130 abuts on the inner peripheral surface of the connection portion 22 and is similar to the bending portion 31 of the first embodiment. This contributes to the regulation of rotation. Since the upper sash 15B of this embodiment forms an inclined portion 30h in the molding 130 that is separated from the corner portion of the boundary between the inner peripheral protruding portion 23b of the frame main body 120 and the connection portion 22, the frame main body It is not necessary to align the molding 130 with respect to the 120 corners, and the requirements regarding component accuracy can be relaxed. In addition, it is the same as that of the first embodiment in that the inner peripheral extending portion 30b of the molding 130 abuts on the inner peripheral protruding portion 23b of the frame main body 120 and is supported, and the inner peripheral protruding portion 23b is provided. The effect is obtained in the same manner as in the first embodiment.

  In the upper sash 15C of the third embodiment shown in FIG. 4, the design portion 223 of the frame body 220 has only a portion corresponding to the outer peripheral protrusion 23a of each of the first and second embodiments. There is no portion corresponding to the circumferential protrusion 23b. In other words, the design portion 223 has only a portion extending toward the outer peripheral side with respect to the connection portion 22, and there is no protruding portion toward the inner peripheral side. The mall 230 has the same configuration as the mall 30 of the first embodiment. Therefore, the inner peripheral side clearance S <b> 2 formed between the inner peripheral side end portion of the design portion 223 of the frame body 220 (the boundary portion between the connection portion 22 and the design portion 223) and the folded portion 32 of the molding 230 is the design portion. In addition to being larger than the outer peripheral gap formed between the outer peripheral end of 223 and the outer bent portion 30f, it is larger than the inner peripheral gap S1 of each of the first and second embodiments. Yes. As a result, the degree of freedom in setting the shape of the molding 230 on the inner peripheral side of the connecting portion 22 is further increased. For example, in the present embodiment, the molding 230 has the same shape as the molding 30 of the first embodiment, but it is also possible to make a change that further reduces the distance between the outer surface portion 30e and the inner peripheral extension portions 30b, 30d. In addition, since the design portion 223 of the frame body 220 is formed in a small size that does not include a protruding portion toward the inner peripheral side, effects of weight reduction and manufacturing cost reduction are also obtained. As in the first and second embodiments, the effect of restricting the rotation of the molding 230 can be obtained by the contact between the bent portion 31 and the connecting portion 22.

  The upper sash 15D of the fourth embodiment shown in FIG. 5 has a configuration common to the frame main bodies 20 and 120 of the first and second embodiments with respect to the frame main body 320. That is, it has the design part 23 including the inner periphery protrusion part 23b. The molding 330 does not have a portion corresponding to the engaging protrusion 30g of each of the first to third embodiments, and the outer peripheral bending portion 30f is an outer peripheral end. In the molding 330, a portion of the outer surface portion 30e close to the outer peripheral bending portion 30f serves as an outer peripheral side mounting portion that is fixed to the outer peripheral protruding portion 23a of the frame body 320 (the outer surface portion 30e is partially outer peripheral side). The double-sided tape 43 fixes the space between the inner surface of the outer surface portion 30e and the outer surface of the outer peripheral projection 23a. As in the present embodiment, the molding 330 may be attached to the design portion 23 (outer peripheral protrusion 23a) of the frame body 320 in a manner other than engagement.

  The upper sash 15E of the fifth embodiment shown in FIG. 6 has the same structure as the frame bodies 20, 120, and 320 of the first, second, and fourth embodiments with respect to the frame body 420. That is, it has the design part 23 including the inner periphery protrusion part 23b. The molding 430 has an inclined portion 30h between the fixed portion 30a and the inner peripheral extending portion 30b, similarly to the molding 220 of the second embodiment. Further, in the molding 430, as in the molding 330 of the fourth embodiment, a portion of the outer surface portion 30e close to the outer peripheral bending portion 30f is fixed to the outer peripheral protruding portion 23a of the frame body 420 with the double-sided tape 43, and the first It does not have a portion corresponding to the engagement protrusion 30g of the third embodiment.

  The upper sash 15F of the sixth embodiment shown in FIG. 7 has a configuration that is common to the frame main body 220 of the third embodiment with respect to the frame main body 520, and only the portion that protrudes to the outer peripheral side with respect to the connection portion 22. The design portion 223 is configured (having no projecting portion toward the inner peripheral side). The molding 530 is configured in common with the molding 330 of the fourth embodiment, and a portion of the outer surface portion 30e close to the outer peripheral bending portion 30f is fixed to the outer peripheral protruding portion 23a of the frame body 520 with a double-sided tape 43, There is no portion corresponding to the engaging protrusion 30g of each of the first to third embodiments.

  Unlike the first to sixth embodiments in which the frame body (20, 120, 220, 320, 420, 520) is an aluminum extrusion-molded product, each embodiment shown in FIGS. 8 to 13 is made of iron. A frame body formed as a roll molded product is used.

  The upper sash 15G of the seventh embodiment shown in FIG. 8 is configured by combining a frame body 50 that is an iron roll-formed product and a molding 60. The molding 60 is formed of an arbitrary material such as metal or synthetic resin. The frame main body 50 includes a vehicle inner frame portion 51 located on the vehicle inner side, a connection portion 52 extending from the vehicle inner frame portion 51 toward the vehicle outer side, and a design portion 53 connected to the vehicle outer side of the connection portion 52. have. The frame body 50 is formed from a single iron plate. In the connection part 52, the iron plates are laminated in three layers, and among these, the two layer parts located on the middle and inner peripheral side are extended to the vehicle inner side to form the vehicle inner frame part 51 having a cylindrical cross section. A holding step portion 54 is formed on a wall portion on the vehicle outer side of the vehicle inner frame portion 51. The design portion 53 has an outer peripheral protruding portion 53 a that protrudes toward the outer peripheral side with respect to the connecting portion 52, and an inner peripheral protruding portion 53 b that protrudes toward the inner peripheral side, and three layers constituting the connecting portion 52. Of these three layers, the outermost layer is bent toward the outer periphery and then folded back to the outside of the vehicle to form the outer peripheral protrusion 53a, and the innermost layer among the three layers constituting the connecting portion 52 is the inner periphery. The inner peripheral protrusion 53b is formed by being bent toward the side and then folded back to the vehicle outer side. In the thickness direction of the door 10, the inner peripheral protrusion 53b is thinner than the outer peripheral protrusion 53a (the interval between the two iron plates is narrow). Further, the protruding amount from the connecting portion 52 (the protruding amount in the direction connecting the inner peripheral side and the outer peripheral side) is smaller in the inner peripheral protruding portion 53b than in the outer peripheral protruding portion 53a. A holding protrusion 55 that protrudes toward the vehicle inner side is formed on the outer peripheral protrusion 53a. A claw portion 56 that protrudes toward the outer peripheral side and faces the holding protrusion 55 is formed at the inner end of the outer peripheral side layer among the three layers constituting the connecting portion 52.

  The molding 60 has substantially the same configuration as the molding 30 of the first embodiment, and engages an engaging projection 60g (outer peripheral side mounting portion) with the outer peripheral protruding portion 53a, and fixes the fixing portion 60a to the frame main body 50. The connecting portion 52 is attached to the frame main body 50 by being brought into contact with (in contact with) the surface on the inner peripheral side and supporting the connecting portion 52 and fastening the fixing portion 60 a and the connecting portion 52 with the rivet 70. In this attached state, the outer surface portion 60e of the molding 60 is located on the vehicle outer side of the design portion 53 of the frame body 50, the outer peripheral bending portion 60f is opposed to the outer peripheral side end portion of the outer peripheral protrusion 53a of the design portion 53, and the inner peripheral extension The installation portion 60 b is positioned along the inner surface of the inner peripheral protrusion 53 b of the design portion 53. A bent portion 61 is formed between the fixed portion 60a and the inner peripheral extending portion 60b of the molding 60, and a folded portion 62 is formed between the outer surface portion 60a and the inner peripheral extending portion 60d. The bending portion 61 of the molding 60 abuts on the inner peripheral surface of the connection portion 52 of the frame body 50, and the molding 60 is restricted from rotating. The molding 60 projects a part of the outer surface portion 60a and the inner peripheral extending portion 60d on the inner peripheral side of the inner peripheral protruding portion 53b of the design portion 53 of the frame body 50, and the inner peripheral side of the inner peripheral protruding portion 53b. The inner circumferential side gap S3 formed between the end portion and the folded portion 62 is larger than the outer circumferential side gap formed between the outer circumferential end portion of the outer circumferential protruding portion 53a and the outer circumferential bent portion 30f.

  In a state where the frame body 50 and the molding 60 are combined, a glass holding portion 71 is formed on the inner peripheral side of the connection portion 52, and a weather strip holding portion 72 is formed on the outer peripheral side of the connection portion 52. The inner peripheral extending portion 60b, the engaging step portion 60c, and the inner peripheral extending portion 60d of the molding 60 constitute an inner peripheral extending portion that extends toward the inner peripheral side with respect to the fixed portion 60a. A side wall on the vehicle outer side of the glass holding portion 71 is formed by the installation portion. A glass run (not shown) is inserted into the glass holding portion 71, and the glass run engages with the engaging step portion 60 c of the molding 60 and the holding step portion 54 of the frame body 50 and is held in the glass holding portion 71. . A weather strip base portion (not shown) is inserted into the weather strip holding portion 72 and is engaged with the holding protrusion 55 and the claw portion 56 to hold the weather strip.
