The convex portion 20c is formed by folding the end portion of the design portion 20a by about 180 degrees, and the vertex portion of the turn is directed toward the inner edge of the sash.

  The inner member 21 is slightly separated inward from the design portion 20a and the back contact portion 21a along the inner surface of the design portion 20a of the outer member 20 in order from the sash outer edge side (vehicle rear side). The opposing facing portion 21b facing each other, the retaining projection 21c projecting to the inner side of the vehicle from the spacing facing portion 21b, and the concave shape projecting to the outer side of the vehicle following the retaining projection 21c and contacting the design portion 20a And an inner frame portion 21i that is formed so as to protrude from the inside of the vehicle so as to surround the glass run storage portion 20b of the outer member 20. The inner frame portion 21i has a box-like cross-sectional shape that gradually decreases in width from the vehicle outer side toward the vehicle inner side, and is opposed to the bottom portion 20g of the glass run storage portion 20b following the concave portion 21d. An inwardly extending portion 21e that extends toward the inside of the vehicle, a connecting portion 21f that extends in the vehicle longitudinal direction following the inwardly extending portion 21e, and an outer portion that extends toward the outside of the vehicle from the connecting portion 21f It consists of the direction extension part 21g. The inwardly extending portion 21e is an inclined surface portion that approaches the sash inner edge side (front) as it proceeds from the vehicle outer side to the vehicle inner side. On the contrary, the outward extending portion 21g is an inclined surface portion that approaches the sash inner edge side (front) as it goes from the vehicle inner side to the vehicle outer side. The frame parallel end portion 20i of the outer member 20 is parallel to the outward extending portion 21g and extends in the same direction.

  The auxiliary member 22 includes a bottom surface portion 22a that is fixed to the inwardly extending portion 21e of the inner member 21, a concave portion 22b that faces the concave portion 21d, and a retaining member that is bent outward from the concave portion 22b. It has a protrusion 22c. The bottom surface portion 22a, the concave portion 22b and the retaining projection portion 22c of the auxiliary member 22 and the portion surrounded by the retaining projection portion 21c and the concave portion 21d of the inner member 21 constitute a weather strip retaining recess. A weather strip leg (not shown) is fitted and held in the strip holding recess. Specifically, the leg portion of the weather strip has a width corresponding to the interval between the concave portion 21d and the concave portion 22b, and the falling-off projection portion 21c and the separation prevention projection portion 22c are prevented from dropping from the weather strip holding concave portion. Be regulated. The weather strip abuts against the center pillar of the vehicle body when the door 10 is closed, and is elastically deformed to prevent water droplets or the like from entering the vehicle.

  The outer member 20 and the inner member 21 are formed as separate members and then joined. This joint is located on the sash inner edge side facing the window opening 13 and on the sash outer edge side opposite to this. At the joint portion on the outer edge side of the sash, the end portion of the design portion 20a of the outer member 20 is folded back and pressed to the inside of the vehicle, and the end portion of the back surface contact portion 21a of the inner member 21 is sandwiched, and the hemming joint portion 23 is configured. Specifically, each of the design portion 20a and the back surface contact portion 21a is formed as a plate-like portion that is generally oriented in the vehicle front-rear direction, and the design portion 20a is in the vehicle outer side, and the back surface contact portion 21a is in the vehicle inner position. Superimposed. Then, the end portion of the design portion 20a is folded back about 180 degrees toward the vehicle inner side so as to cover the end surface of the rear surface abutting portion 21a on the vehicle rear side, and a folded portion 20j is formed. The folded portion 20j comes into contact with the inner surface of the back contact portion 21a, and the front and back surfaces of the back contact portion 21a are sandwiched between the outer members 20. When the folded portion 20j is formed, the outer member 20 and the inner member 21 are joined by pressurizing toward the back contact portion 21a with a predetermined pressure.

  On the other hand, the joint portion on the inner edge side of the sash has the end portion of the outer extending portion 21g of the inner member 21 folded and pressed toward the inner side of the glass run storage portion 20b, and the frame parallel end portion of the outer member 20 The hemming joint 24 is sandwiched by 20i. Specifically, the frame parallel end portion 20i and the outward extending portion 21g are inclined and extend in the thickness direction of the door as plate portions that are substantially parallel to each other, and on the sash inner edge side of the frame parallel end portion 20i. The outwardly extending portion 21g is positioned so as to overlap the facing surface. Then, the end portion of the outward extending portion 21g is folded back by about 180 degrees toward the inside of the glass run storage portion 20b so as to cover the end face of the frame parallel end portion 20i facing the vehicle outer side, and the folded portion 21h is formed. It is formed. The folded portion 21h is in contact with the back side of the frame parallel end portion 20i, and the front and back of the frame parallel end portion 20i are sandwiched between the inner members 21. When the folded portion 21h is formed, the outer member 20 and the inner member 21 are fixed to each other by pressing with a predetermined pressure toward the frame parallel end portion 20i.

  As shown in FIG. 2, the glass run 30 is attached to the glass run storage portion 20 b in a state where the outer member 20 and the inner member 21 are joined at the hemming joint portions 23 and 24. The glass run 30 includes a bottom portion 30a that contacts the bottom portion 20g of the glass run storage portion 20b, a pair of side portions 30b and 30c whose side positions are regulated by the pair of convex portions 20c and 20d, and a pair of concave portions 20e, The projections 30d and 30e that protrude into the inside of 20f to restrict the glass run 30 from dropping in the direction of the inner edge of the sash and extend from the respective tip portions of the pair of side portions 30b and 30c in a direction approaching each other. And have elastic lip portions 30f and 30g. The pair of elastic lip portions 30f and 30g are elastically deformed by coming into contact with the door glass 14 that has entered the glass run storage portion 20b, thereby suppressing vibration of the door glass 14 and accompanying noise. A base end portion (tip portion of the side portion 30b) of the elastic lip portion 30f located on the vehicle outer side is engaged with a folded portion between the design portion 20a and the convex portion 20c of the outer member 20, and this engagement. The elastic lip portion 30f is supported by the portion so as to contact the outer surface of the door glass 14 with an appropriate pressure. Further, the base end portion (tip portion of the side portion 30c) of the elastic lip portion 30g located on the vehicle inner side is engaged with the folded end portion of the folded portion 21h forming the hemming joint 24, and this engagement The elastic lip portion 30g is supported by the portion so as to elastically contact the inner surface of the door glass 14 with an appropriate pressure.

  In the side sash portion 16 configured as described above, the sash inner edge side hemming joint 24 is formed on the extending direction of the outward extending portion 21g constituting the inner frame portion 21i, and the outward extending portion. The end portion of 21g is folded as it is, and the frame parallel end portion 20i is sandwiched. That is, the joining surface of the outer member 20 and the inner member 21 in the hemming joint 24 is substantially parallel to the extending direction of the outward extending portion 21g, and the folded end portion of the folded portion 21h is generally directed to the vehicle outer side. Yes. In other words, the joint surface of the hemming joint 24 does not extend substantially parallel to the design portion 51a toward the window opening as in the conventional hemming joint 54 of FIG. It is in a non-parallel relationship with the design part 20a. In the hemming joint 24 according to the present embodiment, since the direction of the joint surface is set as described above, the protruding amount toward the window opening 13 is suppressed to be small. In the side sash portion 16, the hemming joint 24 is the portion located closest to the inner edge of the door frame 12. Therefore, if the amount of projection of the hemming joint 24 toward the window opening 13 is small, the window opening Thus, a substantial opening area at the periphery of 13 is secured. That is, the field of view of the window periphery can be widened as compared with the conventional hemming joining, and the visibility from the vehicle interior through the window opening 13 is improved.

  In the hemming joint 24, since the folded portion 21h is folded back toward the escape recess 20h side of the glass run storage portion 20b, the folded portion can be obtained by attaching the glass run 30 to the glass run storage portion 20b. Is naturally covered. Therefore, special processing for protecting the hemming joint and waterproofing is unnecessary, and the productivity is excellent.

  In addition, since a part of the outwardly extending portion 21g which is a wide plane portion directly forms the outer surface portion of the hemming joint portion 24 (the surface facing the window opening 13), the hemming joint portion 24 is formed. There is no need to extend the glass run 30 to the outer surface area to improve the appearance, and the glass run 30 can be reduced in size. That is, as shown in FIG. 2, the glass run 30 is engaged with the folded portion between the outward extending portion 21g and the folded portion 21h in the vicinity of the tip portion of the side portion 30c. It is a small shape that does not cover the outwardly extending portion 21g of the previous region. On the other hand, the conventional type hemming joint 54 shown in FIG. 7 has a shape bent with respect to the inner frame 52b, and is covered with the glass run 55 up to the vicinity of the boundary with the inner frame 52b. Since it is necessary to arrange, the glass run 55 will be enlarged.

  The processing steps for the hemming joint 24 are shown in FIG. First, the outer member 20 and the inner member 21 in a temporarily assembled state are set on the fixing jig 40. The fixing jig 40 has a support surface corresponding to the outer surface shape of the connecting portion 21f of the inner member 21 and the outward extending portion 21g, and the outer member 20 so that the outward extending portion 21g faces the horizontal direction. And the inner member 21 is supported. At this time, as shown by a two-dot chain line in FIG. 3, a portion corresponding to the folded portion 21h is a temporary bent portion 21h ′ bent at an acute angle toward the escape recess 20h. Subsequently, the movable mold 41 is set so that the pressing protrusion 41a faces the temporary bending portion 21h ′. The movable mold 41 is movable in the vertical direction in FIG. 3, and the escape recess 20h of the glass run storage portion 20b functions as an escape portion that prevents interference with the pressure protrusion 41a. When the setting of the movable mold 41 is completed, the pressing body 42 is moved downward to abut the movable mold 41. Then, the movable mold 41 is moved downward by receiving the moving force of the pressing body 42, the pressing protrusion 41a presses the temporary bending portion 21h ', and the temporary bending portion 21h' is on the back side of the frame parallel end portion 20i. The folded portion 21h is completed. As described above, the hemming joint 24 can be easily formed with the same number of man-hours as the conventional hemming joining.

  FIG. 4 shows a second embodiment of the present invention. 4 that are denoted by the same reference numerals as those in FIG. 2 have the same structure as that of the previous embodiment, and a description thereof will be omitted. In the hemming joint portion 24 of the previous embodiment, the folded portion 21h is formed at the terminal portion of the outward extending portion 21g on the inner member 21 side. However, in the hemming joint portion 124 in FIG. 20 is different in that a folded portion is formed on the glass run storage portion 20b side. That is, the inner frame portion 21i of the inner member 21 is not provided with a portion corresponding to the folded portion 21h of the previous embodiment, and the end portion of the outward extending portion 21g faces the vehicle outer side. On the other hand, in the outer member 20, the front end portion of the frame parallel end portion 20i is folded back about 180 degrees toward the inner edge of the sash (outside the glass run storage portion 20b) so as to surround the end portion of the outward extending portion 21g. Thus, a folded portion 20k is formed. The outward extending portion 21g is sandwiched between the folded portion 20k and the frame parallel end portion 20i, and the outer member 20 and the inner member 21 are joined. Also in the hemming joining portion 124 of this embodiment, the joining surface of the outer member 20 and the inner member 21 is configured to face the extending direction of the outward extending portion 21g, so that the hemming joining to the window opening side is performed. The protrusion amount of the part 124 is suppressed to be small, and a wide field of view of the periphery of the window opening can be secured.

  FIG. 5 shows a machining process of the hemming joint 124. First, the outer member 20 and the inner member 21 in a temporarily assembled state are set on the fixing jig 140. The fixing jig 140 has a support protrusion 140a that is inserted into the escape recess 20h of the outer member 20 and supports the frame parallel end portion 20i substantially horizontally. The base end portion of the support protrusion 140a engages with the folded portion between the design portion 20a and the convex portion 20c of the outer member 20, and the positional deviation with respect to the fixing jig 140 is prevented. At this time, the portion corresponding to the folded portion 20k is a temporary bent portion 20k ′ bent at an acute angle toward the inner edge of the sash as shown by a two-dot chain line in FIG. Subsequently, the movable mold 141 is set above the fixing jig 140 so that the lower surface thereof faces the provisionally bent portion 20k ′. The movable mold 141 is movable in the vertical direction in FIG. When the setting of the movable mold 141 is completed, the movable mold 141 is dropped and moved downward to abut the upper surface of the fixing jig 140. Then, the movable mold 141 presses the temporary bending portion 20k ′, and the pressurized temporary bending portion 20k ′ is brought into close contact with the back side of the frame parallel end portion 20i to form the folded portion 20k.

  For the joint portion other than the hemming joint between the outer member and the inner member on the inner side of the sash, a joint structure different from that of the above embodiment can be employed. An example is shown in FIG. In FIG. 6, the parts denoted by the same reference numerals as those in FIG. 2 are the same as those in the previous embodiment, and the description thereof is omitted. The outer member 220 in the side sash portion 216 of FIG. 6 does not include a portion corresponding to the design portion 20a of the previous embodiment, and substantially constitutes only the glass run storage portion 20b. The concave portion 20e of the outer member 220 and the back surface contact portion 21a and the concave portion 21d of the inner member 221 are substantially flush with each other, and the outer member 220 and the inner member 221 are along the outer surface of the vehicle. The garnish 60 which consists of another member is attached, and the design part of the side sash part 216 is comprised. The end of the inner member 221 on the sash outer edge side of the back contact portion 21a is folded back wider than the folded portion 20j of the previous embodiment, and is engaged with the edge of the garnish 60.

  The inner member 221 has a weather strip holding recess surrounded by a pair of retaining protrusions 21c, 222c facing each other apart from the vehicle outer side and the vehicle inner side, a pair of concave portions 21d, 222b facing each other, and a bottom 221e-1. This bottom portion 221e-1 is spot welded to the bottom portion 20g of the glass run storage portion 20b. This spot welded portion is a joint portion between the outer member 220 and the inner member 221 that replaces the hemming joint portion 23 of the previous embodiment. The inner member 221 further includes an inwardly extending portion 221e-2 that extends from the retaining protrusion 222c toward the inside of the vehicle, and the inner extending portion 221e-2 is connected to the outer connecting portion 21f and the outer portion. About the direction extension part 21g, the inner frame part 21i of the box-shaped cross section located in the vehicle inside of the glass run storage part 20b is comprised like the previous embodiment.

  Further, the hemming joint 24 on the inner edge side of the sash in FIG. 6 has substantially the same structure as that of the first embodiment shown in FIG. However, the embodiment of FIG. 6 is different in that a retaining protrusion 30h is additionally formed in the vicinity of the upper end of the side portion 30c of the glass run 30. The retaining protrusion 30h enters the escape recess 20h of the outer member 220, engages with the folded portion 21h of the hemming joint 24, and prevents the glass run 30 together with the retaining protrusions 30d and 30e. Have As described above, the relief recess 20h is used as an entry space for the pressure protrusion 41a of the movable mold 41 in the processing step of the hemming joint portion 24 shown in FIG. 3, and the processing step of the hemming joint portion 124 shown in FIG. Is used as an entry space for the support protrusion 140 a of the fixing jig 140. That is, the escape recess 20h functions as an escape portion that avoids interference with the tool for hemming, but this escape recess 20h can also be used as an engagement portion of the retaining projection 30h as shown in FIG. Improved functionality.

  Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to the illustrated embodiment, and can be improved or modified without departing from the gist of the invention. For example, in the inner members 21 and 221 of the illustrated embodiment, the outwardly extending portion 21g of the inner frame portion 21i is an inclined surface portion that approaches the sash inner edge as it goes from the vehicle inner side to the vehicle outer side. A portion corresponding to the side extending portion 21g may be extended without being inclined from the vehicle inner side toward the vehicle outer side (that is, in a direction substantially orthogonal to the design surface portion of the sash). . In this aspect, since the protrusion of the hemming joint in the window glass direction is substantially eliminated, the visibility of the window peripheral edge can be further improved.

  In addition, the illustrated embodiment is applied to the side sash portion of the side door for the front seat of the automobile, but for the front sash of the side door for the front seat, the side sash and the rear sash of the side door for the rear seat, etc. Is also applicable. In other words, the present invention can be applied to any portion of the door frame that has a glass run storage portion and an inner frame portion located on the inner side of the vehicle.
