Further, as above mentioned, by the fastening fixed to the flange portion provided on the upper opening edge of the Rusa Idomenba exist along the vehicle longitudinal direction at both sides of the vehicles, fastening by bolts and nuts Can be easily performed.

Further, as above mentioned, the flange portion of the side member located between the vertical wall and the rear side of the vertical wall on the vehicle front side of the cross member that extends in the vehicle width direction is provided between the two side members hand, by a bottom plate and inserting the flange portion of the floor panel and the side member bolt screwed into a nut provided in the flange portion of the side member of the hook device, by which is fastened to the floor panel and the hook device, the cross Since the member is present, a portion of the side member that cannot be spot-welded to the flange portion of the side member can be reinforced by fastening and fixing it with bolts and nuts simultaneously with the hook device.

Further, in the vehicle hook device fixing structure according to claim 2 , as described above, the position of the flange portion of the side member to which the hook device is fastened and fixed by the bolt and nut is the vertical wall on the vehicle front side of the cross member. And the vertical wall on the rear side of the vehicle, it is possible to reinforce the floor panel at the rear side of the vehicle that is particularly likely to be turned up during a vehicle front collision.

  Embodiments of the present invention will be described below with reference to the drawings.

The vehicle hook device fixing structure according to the first embodiment corresponds to the first and second aspects of the invention.
FIG. 1 is a plan view of a main part showing a hook device fixing structure for a vehicle according to the first embodiment, FIG. 2 is a longitudinal sectional view taken along line AA of FIG. 1, and FIG. It is a perspective view which shows the vehicle body framework part which shows.

The vehicle hook device fixing structure of the first embodiment includes a hook device 1, a floor panel 2, a retainer 3, a carpet 4, a side member 5, a cross member 6, a bolt 7, a weld nut 8, It has.
More specifically, the hook device 1 is provided in a fixed state on the floor of a luggage space of a vehicle, and serves to moor and fix a load collapse prevention net, rope, etc. It is composed of a box-shaped main body 11 provided with a flange 11a for attachment at the outer peripheral opening edge, a lid 12 extending horizontally from the opening edge, and a bearing block 13 fixed to the bottom plate 11b of the box-shaped main body 11. A housing 1a, a pivot shaft 14 accommodated in the housing 1a and pivotally supported by the housing 1a, and a U-shaped arm 15 having a handle 15a at a central portion coupled to both ends thereof. It is comprised by the latching | locking part 1b.

The hook device 1 is prevented from rotating by attaching the box-shaped main body 11 to the rectangular holes 31 and 41 formed in the retainer 3 and the carpet 4 with the flange 11a remaining. The bolts 7 are inserted from above into the four bolt insertion hole groups B formed in the bearing block 13, the bottom plate 11 b, the floor panel 2, and the flange portion 51 of the side member 5 that is the vehicle body skeleton portion. The flange 51 is fastened and fixed to the flange 51 of the side member 5 which is the floor panel 2 and the vehicle body skeleton by screwing and fastening to the weld nut 8 welded in advance to the back side of the flange 51.
The range of the cross-sectional recess of the cross member 6 is a range indicated by B in FIG. 3. Specifically, the position in the vehicle front-rear direction is the vertical wall 6 a on the vehicle front side of the cross member 6 and the vehicle rear side. The position between the side vertical wall 6b is said.

  Further, the position of the flange portion 51 of the side member 5 to which the hook device 1 is fastened and fixed by the bolt 7 and the weld nut 8 is within the range of the cross-sectional recess of the cross member 6 as shown in FIG. It is set to be a portion on the vehicle rear side within the range of the recess.
