The vehicle rear suspension support portion structure 60 is a structure that can generate a sufficient bolt tightening force and a uniform bolt tightening force when the rear suspension 63 is attached to the underbody 12.

  FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1. A vehicle spare tire mounting structure 30 is formed on a vehicle body floor 31 to be attached to a recess 33 for storing a spare tire 32 and a lower surface of the recess 33. A spare tire 32 is mounted on the vehicle body floor 31 by a reinforcing plate 34, a hooked nut 37 that abuts the flange 35 below the reinforcing plate 34, and the trunk 36 penetrates the reinforcing plate 34. And a cross member 41 that reinforces the vehicle body floor 31 by passing it to the lower portion of the vehicle body floor 31 and covers the hooked nut 37 and the reinforcing plate 34 together.

The vehicle body floor 31 includes a bottom panel 42 that improves the rigidity of the rear portion, and the concave portion 33 includes a through hole 43 through which the trunk portion 36 of the hooked nut 37 passes.
The reinforcing plate 34 was formed with a plate through hole 44 for passing through the body portion 36 of the hooked nut 37 and a bead 45 for improving the rigidity of the reinforcing plate 34 itself.
The holder 38 includes a screw through hole 46 that allows the attachment mounting screw 39 to pass therethrough, and a presser portion 47 that presses the spare tire 32.

FIG. 3 is a plan view of a vehicle spare tire mounting structure according to the present invention. The vehicle spare tire mounting structure 30 is a spare tire for a vehicle 10 (see FIG. 1) capable of mounting a spare tire 32 on a vehicle body floor 31.

It can be said that the cross member 41 is covered.
The cross member 41 is a member whose both ends are supported by the left and right rear lower frames 61, 61 of the underbody 12 (see FIG. 1).

  For example, if the number of welding points such as brackets can be reduced, it is advantageous to reduce the welding work time. If the thickness of the brackets and the like can be reduced, the weight of the vehicle body can be reduced. This is preferable because it is possible.

Therefore, a reinforcing plate 34 is provided on the lower surface of the vehicle body floor 31, and a flange portion 35 (see FIG. 2) of the hooked nut 37 is applied to the lower surface of the reinforcing plate 34, and a trunk portion 36 of the hooked nut 37 is attached to the reinforcing plate 34.

When a spare tire (not shown) is pressed against the vehicle body floor 201, a force in the direction of peeling the bracket 202 from the vehicle body floor 201 acts as indicated by arrows a1 and a1. Therefore, in order to increase the rigidity of the bracket 202, it is required to change the plate thickness or to increase the number of welding locations of the bracket 202. This cannot reduce the weight of the vehicle body.

In (b), a vehicle spare tire mounting structure 210 is a structure in which a nut 213 is welded to a bracket 212, the bracket 212 is welded to a holder 215, and the holder 215 is welded from the lower surface of the vehicle body floor 211.

The force that directly peels off the welded portion does not act.
However, in the vehicle spare tire mounting structure 210, the nut 213 is positioned below the vehicle body floor 211, so that workability when the mounting screw 214 is screwed into the nut 213 is poor.

  In (c), the vehicle spare tire mounting structure 30 includes a reinforcing plate 34 attached to the lower surface of the vehicle body floor 31, and a flange portion 35 of a hooked nut 37 is placed under the reinforcing plate 34 and the reinforcing plate 34 is By passing through the body portion 36 of the hooked nut 37, the mounting screw 39 is screwed into the hooked nut 37, and when the spare tire 32 (see FIG. 2) is attached to the vehicle body floor 31, the reinforcing plate 34 is attached to the vehicle body floor 31 with an arrow. It is possible to bite like a3 and a3 and to bite the flange portion 35 of the hooked nut 37 on the reinforcing plate 34.

As a result, the welding location of the reinforcing plate 34 to the vehicle body floor 31 and the welding location of the flanged nut 37 to the reinforcing plate 34 can be reduced, and the thickness of the reinforcing plate 34 can be reduced.
Further, since the tip of the hooked nut 37 protrudes from the vehicle body floor 31, workability when the mounting screw 39 is screwed into the hooked nut 37 is good. That is, it is possible to improve the visibility when the mounting screw 39 is screwed into the nut.
