Description

  The present invention relates to a temporary damper holding structure for temporarily holding a damper on the vehicle body side in order to facilitate the assembly of the damper to the vehicle body.

There is one in which a temporary fixing body having a locking piece that can be elastically deformed in the radial direction is attached to the head of the damper. This is because when the damper is inserted into the damper base from below, the temporary holding member is inserted into the mounting hole formed in the damper base while deforming the locking piece, and the locking piece gets over the mounting hole. As a result, it spreads radially outward and is locked to the damper base, and as a result, the damper is temporarily held on the vehicle body side (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 6-1159

  In the above structure, a temporary fixing body having a locking piece portion that can be deformed in the radial direction is attached to the head portion of the damper. Therefore, work on the peripheral portion, for example, fastening of a nut to a screw portion of the damper There is a possibility of affecting the work performed thereafter, such as the nail part obstructing the work.

  For this reason, the locking piece is extended from the vehicle body side, and when the damper is inserted into the damper base from below, the locking piece is moved over the riding over portion provided in the damper to lock the overpassing portion. A damper temporary holding structure is considered in which the damper is temporarily held on the vehicle body side by being locked to one part. If the locking piece portion is extended from the vehicle body in this manner, the degree of freedom of arrangement of the locking piece portion is increased, and the influence on the work performed thereafter can be minimized.

  However, when configured as described above, when the overpass portion of the damper passes over the locking piece portion, there is a possibility that the member on the vehicle body side on which the locking piece portion is disposed is deformed due to the displacement of the locking piece portion. A separate mechanism for preventing such deformation had to be provided, and there was room for further improvement in terms of cost reduction.

  Accordingly, an object of the present invention is to provide a damper temporary holding structure that does not affect the work performed after temporary holding and can reduce the cost.

In order to achieve the above object, according to a first aspect of the present invention, a damper (for example, the rear damper 64 in the embodiment) is placed on a damper base (for example, the rear damper base 33 in the embodiment) on the vehicle body (for example, the vehicle body 11 in the embodiment) side.

It is a concave part extended along the direction orthogonal to the extension direction of the said locking piece part, It is characterized by the above-mentioned.

According to the first aspect of the invention, when the damper is inserted into the damper base on the vehicle body side from below, when the claw portion provided on the damper presses the locking piece portion extending from the vehicle body side, the locking piece The bending induction part provided in the part is easily bent, and the vehicle body side member provided with the locking piece part is prevented from being deformed. Thereafter, when the claw part gets over the locking piece part, the pressing part of the claw part is released, so that the bending inducing part easily returns to the original state, and the locking piece part locks the claw part. In this way, the provision of the locking piece on the vehicle body side eliminates the possibility of affecting the work performed after temporary holding, and the locking piece is provided with a simple structure of providing a deflection inducing portion. The deformation of the member on the vehicle body side provided with the one part can be prevented, and the cost can be reduced.

In addition , since the bending inducing portion is a concave portion extending along a direction orthogonal to the extending direction of the locking piece portion, it can be easily deformed and returned with a simpler configuration. Therefore, the cost can be surely reduced.

Yes.

  In the gusset 56, mounting holes 62 that are aligned with the mounting holes 35 of the rear damper base 33 are formed in the flange portions 60. The gusset 56 is attached to the inner panel 20, the outer panel 21, the rear damper base 33 and the rear floor panel 39 at the flange portion 60.

  As shown in FIG. 5, the rear damper (damper) 64 attached to the rear damper base 33 includes an insertion portion 65 to be inserted into the insertion hole 34 and an attachment flange on the proximal end side of the insertion portion 65. Part 66 and a screw part 67 that is provided at a position different from the insertion part 65 of the attachment flange part 66 by 180 degrees and is inserted into the attachment hole 35. A claw portion (passover portion) 68 that protrudes in the direction of the locking piece portion 50 of the hooking bracket 45 in a state that matches the position and has a protruding tip side bent downward is located above the mounting flange portion 66 of the insertion portion 65. It is formed on the top.

  The rear damper 64 is inserted and attached to the rear damper base 33 from below. At this time, the gusset 56 described above is fastened together with the rear damper 64 to the rear damper base 33. That is, first, as shown in FIG. 6, the operator places the gusset 56 on the rear damper base 33 and the rear floor panel 39 so that the positions of the mounting holes 62 are aligned with the mounting holes 35 of the rear damper base 33. With the rear damper 64 placed from below the rear damper base 33, the insertion portions 65 are inserted into the insertion holes 34, and the screw portions 67 are attached to the attachment holes 35 of the rear damper base 33 and the attachment holes 62 of the gusset 56. Insert into.

  At this time, the gusset 56 covers the opening side of the concave wall portion 30, that is, the inner side in the vehicle width direction. Therefore, the insertion portion 65 after passing through the insertion hole 34 of the rear damper 64 is also covered with the gusset 56. One cannot hold this part by hand. However, when the rear damper 64 is inserted into the rear damper base 33 as described above, at least after each screw portion 67 starts to enter each mounting hole 35 of the rear damper base 33, as shown in FIG. The formed claw portion 68 is brought into contact with the front end side of the concave portion 52 of the locking piece portion 50 of the hook bracket 45 joined to the concave wall portion 30, and the locking piece portion 50 is moved to the plate by further raising the rear damper 64. Press in the thickness direction. Then, as shown in FIG. 8, the locking piece portion 50 is easily elastically deformed by the concave portion 52, and the distal end side of the locking piece portion 50 is displaced in a direction away from the rear damper 64 following the pressing of the claw portion 68. Then, when the claw portion 68 climbs over the locking piece 50 by further raising the rear damper 64, the locking piece 50 is released from the pressing by the claw 68 as shown in FIG. Returning to the original shape, the distal end side of the locking piece portion 50 is displaced in the direction of the rear damper 64 to enter the lower side of the claw portion 68. Therefore, after that, even if the rear damper 64 is about to fall by releasing the holding of the rear damper 64 by the operator, the claw portion 68 is locked to the locking piece portion 50 and the dropping is restricted.

  The rear damper 64 is attached to the rear damper base 33 by screwing the nut member 70 to each screw portion 67 protruding from the gusset 56 of the rear damper 64 temporarily fixed in this manner, as shown in FIG. The gusset 56 is fastened together with the rear damper 64 together with the rear damper base 33.

  The upper part of the gusset 56 attached to the vehicle body is joined to the reinforced inner panel 20 and outer panel 21 of the rear wheel house inner 12, and the lower part is joined to the rear cross member 40 to connect them. I will let you.

  According to the present embodiment described above, when the rear damper 64 is inserted into the rear damper base 33 on the vehicle body 11 side from below, the claw portion 68 provided on the rear damper 64 extends from the vehicle body 11 side. When the portion 50 is pressed, the concave portion 52 provided in the locking piece 50 is easily bent, and the outer panel 21 that is a member on the vehicle body 11 side provided with the locking piece 50 is deformed. To prevent it. Thereafter, when the claw portion 68 gets over the locking piece portion 50, the pressing of the claw portion 68 is released, so that the concave portion 52 easily returns to the original state, and the claw portion 68 is engaged with the locking piece portion 50. Stop. As described above, the provision of the locking piece portion 50 on the vehicle body 11 side eliminates the possibility of affecting the work performed after the temporary holding, and the simple configuration in which the recessed portion 52 is provided in the locking piece portion 50. Thus, the deformation of the outer panel 21 on the vehicle body 11 side where the locking piece portion 50 is provided can be prevented, and the cost can be reduced.

  In addition, it is possible to reliably perform easy deformation and return with a simpler configuration of the recessed portion 52 extending along the direction orthogonal to the extending direction of the locking piece portion 50. Therefore, the cost can be surely reduced.

  In the above embodiment, the example in which the gusset 56 is placed before the rear damper 64 has been described. However, the rear damper 64 may be inserted before the gusset 56 is placed. The claw portion 68 can be reliably hooked to the locking piece portion 50 by inserting the locking piece portion 50 while pressing the locking piece portion 64.

  In the above embodiment, the rear damper 64 has been described as an example, but of course, the present invention can also be applied to a front damper.
