Abstract

A valve protection structure for a vehicle includes: side members; a hydrogen tank disposed between the side members; and a valve member installed to project from a vehicle-widthwise end face of the hydrogen tank. The side member has a convex member projecting inward in the vehicle widthwise direction from an inner wall part, the convex member is placed at a position offset with respect to the valve member and opposite the hydrogen tank in the vehicle widthwise direction, and a vehicle-widthwise distance between a tip part of the convex member and a portion of the hydrogen tank opposite the tip part of the convex member in the vehicle widthwise direction is set shorter than a vehicle-widthwise distance between a tip part of the valve member and a portion of the side member opposite the tip part of the valve member in the vehicle widthwise direction.

First claim

We claim:

1. A valve protection structure for a vehicle comprising:
a pair of left and right side members which extend in a longitudinal direction of a vehicle body;
a fuel tank which is disposed between said left and right side members; and
a valve which is installed to project outward in a vehicle widthwise direction from a vehicle-widthwise end face of said fuel tank, the vehicle-widthwise end face of said fuel tank facing one of the left and right side members, wherein
the one of said left and right side members includes a convex part that projects inward in the vehicle widthwise direction from a vehicle-widthwise inner side face of the one of the side members,
said convex part is disposed opposite to said vehicle-widthwise end face of said fuel tank in the vehicle widthwise direction and disposed at a position offset with respect to said valve, and
a vehicle-widthwise distance between a tip part of said convex part and a portion of said fuel tank opposite to said tip part of said convex part in the vehicle widthwise direction is set shorter than a vehicle-widthwise distance between a tip part of said valve and a portion of the one of the side members opposite to said tip part of said valve in the vehicle widthwise direction.

2. The valve protection structure according to claim 1 , wherein
said convex part is constituted of a convex member attached to the one of the side members, and
a lower part of said convex member extends to a bottom face of the one of the side members and is attached to said bottom face.

3. The valve protection structure according to claim 1 , wherein said convex part includes a slit extending in the vehicle widthwise direction.

4. The valve protection structure according to claim 1 , wherein
said fuel tank includes:
a fuel tank body which is capable of storing fuel therein; and
a tank cover which is installed on a vehicle-widthwise end part of said fuel tank body and on which said valve is mounted, and

said tank cover has a projection part that projects outward in the vehicle widthwise direction from a vehicle-widthwise end face of said tank cover, the projection part being disposed at a position opposite to said convex part in the vehicle widthwise direction.

5. A vehicle comprising the valve protection structure according to claim 1 .

6. The valve protection structure according to claim 1 , wherein said convex part is disposed at a position offset with respect to said valve in a direction orthogonal to an axial direction of the valve.

7. The valve protection structure according to claim 1 , wherein the one of the side members includes a notch part at a position opposite to the valve in the vehicle widthwise direction, the notch part having a shape corresponding to an outer shape of the valve.

8. The valve protection structure according to claim 1 , wherein said convex part is disposed at a position offset upward with respect to said valve.

9. A valve protection structure for a vehicle comprising:
a pair of left and right side members which extend in a longitudinal direction of a vehicle body;
a fuel tank which is disposed between said left and right side members; and
a valve which is installed to project outward in a vehicle widthwise direction from a vehicle-widthwise end face of said fuel tank, the vehicle-widthwise end face of said fuel tank facing one of the left and right side members, wherein
the one of said left and right side members includes a convex part that projects inward in the vehicle widthwise direction from a vehicle-widthwise inner side face of the one of the side members,
said convex part is disposed opposite to said vehicle-widthwise end face of said fuel tank in the vehicle widthwise direction and disposed at a position offset with respect to said valve, and
a portion of the one of the side members, which is located at a same position as said valve in the longitudinal direction with respect to the vehicle, is offset upward with respect to said valve.

10. The valve protection structure according to claim 9 , wherein said convex part is disposed at the position offset with respect to said valve in a direction orthogonal to an axial direction of the valve.

11. The valve protection structure according to claim 9 , wherein said convex part is disposed at a position offset and upwardly located with respect to said valve.

12. The valve protection structure according to claim 9 , wherein a vehicle-widthwise distance between a vehicle-widthwise inner end of said convex part and a portion of said fuel tank opposite to said inner end of said convex part in the vehicle widthwise direction is set shorter than a vehicle-widthwise distance between a vehicle-widthwise outer end of said valve and a portion of the one of the side members opposite to said outer end of said valve in the vehicle widthwise direction.
