Claims

1. A cylinder head cover comprising:

a body; and

a high rigidity part having a higher rigidity than the body;

wherein a part between both ends of a fuel pipe is mounted to the high rigidity part.

2. The cylinder head cover as claimed in claim 1, wherein

the high rigidity part is a flange part formed on an outer periphery of the body, and

the flange part is used to attach the cylinder head cover to an external member.

3. The cylinder head cover as claimed in claim 2, wherein

the flange part is thicker than the body.

4. The cylinder head cover as claimed in claim 1, wherein

the cylinder head cover is mounted to a cylinder head,

the body covers the cylinder head, and

the fuel pipe is overlapped with the body and extends to the cylinder head.

5. The cylinder head cover as claimed in claim 1, wherein

the fuel pipe is mounted to the high rigidity part of the cylinder head cover and not mounted to a part other than the high rigidity part.

6. The cylinder head cover as claimed in claim 1, wherein
