The rear end of firmware 16.
Multiple reinforcements 20,21,22 are arranged to have between which interval, thus from being positioned at
The adjacent domain of the girth member 16 on mid portion 14 on the diapire 12 storing part 4 radially
Stretch out on direction.Diapire 12 is downwardly concaved to the degree of several millimeters to form reinforcement 20-22.
Additionally, be provided with the most altogether 11 reinforcement 20-22, in these reinforcements,
Due to the restriction of installing space, the adjacent domain of the centre on vehicle-width direction (horizontal direction)
In the rear end of three reinforcements 20 and 21 be integrally formed.
Especially, in the present embodiment, multiple (being five in present embodiment) of front side are strengthened
Muscle 20 and 21(is arranged in the adjacent domain of centre in the vehicle width direction) not at step part
Formed in 15 and be created as at step part 15 being separated.
It addition, the outer end in the radial direction of reinforcement 20 and 22 extends to so that in radial direction side
Upwards outwards beyond the marginal portion 25 storing part 4.
According to above-mentioned structure, in vehicle 1, because inputting to the stretching storing part 4 from hook 17
With compressive load by reinforcement 20 and 21 and step part 15 effectively distribute to front side, because of
And the concentration of local of load can be suppressed.
Here, reinforcement is formed as the case of comparative examples (correlation technique extended on step part 15
Structure) compared with the above-mentioned embodiment of the present invention, specifically describe and storing in part 4
