Abstract

A tank mounting structure includes a frame, a band, and a tank protector. The frame is configured to fix the tank. The band is configured to fix the tank in a state where the band sandwiches the tank with the frame and the band deforms in accordance with expansion or contraction of the tank. The tank protector is configured to be fixed to an inner side of the band or an outer side of the band.

First claim

What is claimed is:

1. A tank mounting structure comprising:
a first member that fixes a tank;
a second member configured to fix the tank in a state where the second member sandwiches the tank with the first member and wherein the second member synchronizes with the tank; and
a tank protector configured to be fixed to an outer side of the second member;
wherein one end portion of the second member is fixed to the first member through a hinge and a first bolt and another end portion of the second member is fixed to the first member by a second bolt while applying a pressure force to the tank by using an elastic body.

2. The tank mounting structure according to claim 1 , wherein
the tank protector includes a center member and end portion members, the center member being provided on an outer side of a cylinder portion that is a cylindrical portion of the tank, and the end portion members being provided on outer sides of dome portions, respectively, the dome portions being on both end sides of the cylinder portion of the tank, respectively; and
the end portion members are thicker than the center member.

3. The tank mounting structure according to claim 2 , wherein a lower end of each of the end portion members of the tank protector is positioned lower than a lower end of the center member of the tank protector.

4. The tank mounting structure according to claim 1 , wherein shear strength of the tank protector is greater than shear strength of the second member.

5. The tank mounting structure according to claim 1 , wherein the second member is made from metal.

6. The tank mounting structure according to claim 1 , wherein the second member is made from an elastic resin material.

7. A vehicle comprising the tank mounting structure according to claim 1 .
