Abstract

Plural canister bodies supported by rocker members are disposed below a floor panel. The canister bodies are housed in a case. Lower couplers are disposed above the canister bodies. The lower couplers abut a cover member of the case. Upper couplers are disposed between the cover member and the floor panel.

First claim

What is claimed is:

1. A vehicle lower section structure comprising:
a floor panel that is provided at a lower section of a vehicle cabin;
a circular cylinder shaped high pressure canister that is disposed below the floor panel and that is supported by a vehicle framework member;
a case that houses the high pressure canister; and
a load transmission member that is disposed between the floor panel and the high pressure canister that includes a first portion located outside the case and a second portion located inside the case, and that transmits load from the floor panel to the high pressure canister.

2. The vehicle lower section structure of claim 1 , wherein the load transmission member is formed by an elastic body having elastic properties.

3. The vehicle lower section structure of claim 1 , further comprising:
a support panel that is disposed so as to cover a lower face of the high pressure canister and that supports the high pressure canister, and wherein:
the vehicle framework member includes a pair of rocker members arranged on each vehicle width direction outer side and extending along a vehicle front-rear direction, and
the support panel is coupled to the rocker members at both vehicle width direction edge portions of the support panel and is disposed between the pair of rocker members.

4. The vehicle lower section structure of claim 2 , further comprising:
a support panel that is disposed so as to cover a lower face of the high pressure canister and that supports the high pressure canister, and wherein:
the vehicle framework member includes a pair of rocker members arranged on each vehicle width direction outer side and extending along a vehicle front-rear direction, and
the support panel is coupled to the rocker members at both vehicle width direction edge portions of the support panel and is disposed between the pair of rocker members.

5. The vehicle lower section structure of claim 3 , wherein
the case is a box-shaped case including a bottom wall formed by at least pan of the support panel, a peripheral wall projecting upward from the bottom wall so as to surround the bottom wall, and a cover member disposed on the opposite side of the peripheral wall to the bottom wall, and
the first portion of the load transmission member includes an upper coupler coupling an upper face of the cover member and the floor panel together, and the second portion of the load transmission member includes a lower coupler coupling a lower face of the cover member and the high pressure canister together.

6. The vehicle lower section structure of claim 4 , wherein
the case is a box-shaped case including a bottom wall formed by at least part of the support panel, a peripheral wall projecting upward from the bottom wall so as to surround the bottom wall, and a cover member disposed on the opposite side of the peripheral wall to the bottom wall, and
the first portion of the load transmission member includes an upper coupler coupling an upper face of the cover member and the floor panel together, and the second portion of the load transmission member includes a lower coupler coupling a lower face of the cover member and the high pressure canister together.

7. The vehicle lower section structure of claim 1 , wherein a plurality of high pressure canisters are disposed along the floor panel such that a cylinder axial direction of each high pressure canister runs in a same direction.

8. The vehicle lower section structure of claim 2 , wherein a plurality of high pressure canisters are disposed along the floor panel such that a cylinder axial direction of each high pressure canister runs in a same direction.

9. The vehicle lower section structure of claim 3 , wherein a plurality of high pressure canisters are disposed along the floor panel such that a cylinder axial direction of each high pressure canister runs in a same direction.

10. The vehicle lower section structure of claim 5 , wherein a plurality of high pressure canisters are disposed along the floor panel such that a cylinder axial direction of the each high pressure canister runs in a same direction.

11. The vehicle lower section structure of claim 1 , wherein the high pressure canister is disposed with a length direction of the high pressure canister running in a vehicle front-rear direction.

12. The vehicle lower section structure of claim 2 , wherein the high pressure canister is disposed with a length direction of the high pressure canister running in a vehicle front-rear direction.

13. The vehicle lower section structure of claim 3 , wherein the high pressure canister is disposed with a length direction of the high pressure canister running in a vehicle front-rear direction.

14. The vehicle lower section structure of claim 5 , wherein the high pressure canister is disposed with a length direction of the high pressure canister running in a vehicle front-rear direction.

15. The vehicle lower section structure of claim 1 , wherein the first portion of the load transmission member and the second portion of the load transmission member are disposed at mutually superimposed positions in plan view.
