The vehicular back door 1 includes a resin inner panel 10 on a front side of a resin door body and a resin outer panel 6 on a rear side. The door main body 1a joined in the state which mutually opposed is provided. The front side and the rear side are a front side in a state where a vehicle body rear door C provided at the rear end of a vehicle body body such as an ordinary car or a light car is covered with a vehicle back door 1 and The back side. The joining method of the resin inner panel 10 and the resin outer panel 6 is not particularly limited, such as adhesion, fitting, welding, and bolt fastening. The resin inner panel 10 and the resin outer panel 6 are made of resin molded products having excellent strength and rigidity. The door main body 1a includes an upper portion 1b that constitutes an upper portion and is provided with a window portion 3, and a lower portion 1c that is located below the upper portion 1b. For example, the lower part 1c is provided with a license plate attachment part 5. The resin outer panel 6 includes an upper outer panel 6b on the upper portion 1b side and a lower outer panel 6a on the lower portion 1c side, and the window portion 3 is disposed therebetween. Further, as shown in FIG. 4, an internal space 7 is provided between the inner panel 10 and the lower outer panel 6a. In this way, most of the door body 1a is formed of a resin molded product having a relatively high strength and a good appearance, thereby improving the appearance while reducing the weight.

  On the other hand, as shown in FIGS. 1 and 4, the resin inner panel 10 is detachably connected to the lower edge portion of the vehicle body rear opening C on the inner space 7 side of the portion along the lower edge portion of the lower portion 1 c. A metal engagement device mounting bracket 14 for mounting a mating engagement device (not shown) is attached. The shape of the engagement device mounting bracket 14 is not particularly limited.

  For example, a pair of left and right hinge portions 12 fixed to the upper edge portion of the vehicle body rear opening C is attached to a portion of the upper portion 1b positioned above the window portion 3. A metal reinforcing side bracket 13 is connected to each hinge portion 12 by a bolt or the like. The reinforcing side bracket 13 is provided from the inner space 7 of the upper portion 1b to the inner space 7 of the lower portion 1c along the outer periphery of the door body 1a of the resin inner panel 10. Although not shown in detail, the reinforcing side bracket 13 is made of a steel plate or the like that is fixed to a boss provided on the resin inner panel 10 with a bolt or the like. Further, although not shown, the rigid reinforcing side bracket 13 is provided with a mounting portion for a damper that assists in opening and closing the vehicle back door 1. The rigidity of the upper part 1b with the window part 3 is mainly improved by the reinforcing side bracket 13. The vehicle back door 1 can open and close the vehicle body rear opening C by rotating in the vertical direction around the hinge portion 12.

  And as shown in FIG.1 and FIG.4, the engagement apparatus attachment bracket 14 and the reinforcement side bracket 13 are connected with the wire 15 as a linear body. As a linear body, the wire rope, the cable, etc. which match | combined the wire, the metal fiber, the resin fiber, etc. more, for example, may be sufficient, and a single wire or a strand wire may be sufficient. Further, the material may be a metal or may contain a resin fiber or the like. Wire mounting screws 16 passed through annular portions 15 a provided at both ends of the wire 15 are fastened to screw holes (not shown) of the engaging device mounting bracket 14 and the reinforcing side bracket 13, respectively.

  A recess 20 that is recessed backward is formed between the engaging device mounting bracket 14 and the reinforcing side bracket 13 at the lower portion of the resin inner panel 10. As shown in FIG. 3, the recess 20 has a shape bulging into a rectangular parallelepiped when viewed from the rear side. The front side of the recess 20 is covered with a cover panel 11 made of a resin molded product, for example. The cover panel 11 can be opened during maintenance work or the like.

  On the bottom surface (rear surface) of the recess 20, a wire holding portion 21 that holds the wire 15 and serves as a linear body holding portion is integrally provided. Specifically, the wire holding part 21 is provided in a seat part 22 that is recessed further rearward than the recessed part 20. As shown in FIG. 3, when viewed from the rear, the seat portion 22 has a rectangular parallelepiped shape that bulges backward. As shown in an enlarged view in FIG. 5, the left and right inner sides and the upper side of the wire holding portion 21 are chamfered, and a wire abutting portion 22 b that abuts when the wire 15 is attached is provided. As shown in FIG. 6, the wire contact portion 22b is formed substantially vertically, but may be inclined so that the wire 15 can be easily pulled up and does not become under when the mold is removed. The wire holding portion 21 is formed on the bottom surface of the recess 20 covered with the cover panel 11 from the front side, and the rear side is covered with the lower outer panel 6a and does not appear in appearance, so that the appearance is good.

  As shown in FIG. 5, the seat portion 22 has a holding piece 24 surrounded by a slit 23. The shape of the holding piece 24 may be a substantially rectangular shape (tongue shape) surrounded by slits 23 on three sides as in this embodiment, or the tip side may be rounded. As shown in FIGS. 5 to 7, the wire 15 is sandwiched and held between the edge of the slit 23 and the holding piece 24. On the open end (tip) side of the holding piece 24, an inclined surface 24 a that is inclined rearward toward the tip is formed so that the wire 15 can be easily held when the wire 15 is pulled up.

  As shown in FIG. 1, the wire 15 is disposed between the engagement device mounting bracket 14 and the reinforcing side bracket 13 in a straight line when viewed from the front-rear direction with the vehicle body rear opening C closed. When viewed from the top, it is arranged in a reverse “C” shape.

  Next, a procedure for attaching the wire 15 related to the vehicle back door 1 according to the present embodiment will be described.

  First, the wire attachment screws 16 passed through the annular portions 15 a provided at both ends of the pair of wires 15 are fastened to the screw holes of the engagement device attachment bracket 14 and the reinforcement side bracket 13, respectively. At this time, as indicated by an imaginary line in FIGS. 1 and 4 to 7, the respective wires 15 are at positions deviated from the seat portion 22, and the wires 15 are slackened. For this reason, the fastening operation of the wire mounting screw 16 is easy. However, if the wire 15 is too slack before being pulled, the tension after the pulling cannot be maintained, so that a certain amount of tension is required in a state where the wire 15 is in contact with the wire contact portion 22b.

  Next, as shown in FIG. 6, the wire 15 is pulled up in the direction of the arrow. The seat is placed on the rear surface 22a. At this time, since the inclined surface 24a is provided, the wire 15 is smoothly guided to the slit 23 side. When in this position, the position of the seat rear surface 22a is set such that the wire 15 is pulled backward when the seat 15 is viewed with the vehicle body rear opening C closed, so that there is no looseness. That is, as shown in FIG. 6, assuming that the position at the shortest distance connecting the reinforcing side bracket 13 and the engagement device mounting bracket 14 is a Y point, the Y point from the center of the wire 15 at the wire contact portion 22b. If the distance up to X is X, the height 15 is secured because the wire 15 is pulled and becomes a straight line while maintaining an appropriate tension. The height Z is the depth Z when the seat 22 is viewed from the front side. Since the resin inner panel 10 is a resin molded product, it can be molded even in a complicated shape, and the height Z can be easily adjusted at the time of molding, but at least Z> X needs to be satisfied in order to secure the tension. In the present embodiment, the seat portion 22 is formed to be recessed on the back side of the concave portion 20, and the holding piece 24 is formed by being surrounded by the slit 23, so that it is an injection mold without providing a slide die. Can be molded. In this embodiment, since the wire 15 can be stretched in a straight line, it is possible to easily prevent slack.

  When the wire 15 is pulled up, as shown in FIG. 1, the open end of the holding piece 24 faces the upper portion 1 b side in a direction intersecting with the extending direction of the wire 15 when the rear opening C is closed. . Specifically, in FIG. 1, the open end is directed to the left and right inner sides and the upper side. For this reason, even when the door body 1a is bent when the resin door body 1a is opened and closed, the wire 15 moves toward the opposite side of the upper portion 1b, that is, in the direction of expanding downward and right and left. Since the open end of the holding piece 24 faces the opposite side, the wire 15 does not come off the holding piece 24.

  And since the wire 15 is reliably hold | maintained by the wire holding part 21, it is hard to vibrate and a sound does not generate | occur | produce.

  Therefore, according to the vehicle back door 1 according to the present embodiment, the engaging device mounting bracket 14 and the reinforcing side bracket 13 are connected by the wire 15, and the engaging device mounting bracket 14 is connected to the lower portion 1 c of the resin inner panel 10. A recess 20 recessed backward is provided between the reinforcing side bracket 13 and a holding piece 24 surrounded by a slit 23 is formed in the recess 20, and the wire 15 is sandwiched between the edge of the slit 23 and the holding piece 24. The wire 15 can be easily tensioned easily while it is difficult to generate vibration.

  In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or a use.
