Claims

[Scope of utility model registration request]

The cap body is adapted to be airtightly engaged with the fuel fill hole of the fuel tank, and the release mechanism is provided on the cap body and, when rotated by a key, drives a release mechanism that releases the cap body from the fuel fill hole. a key cylinder provided in the cap body so as to communicate between the inside and outside of the fuel tank and adjacent to the key cylinder; and a communication hole provided in the communication hole so as to partition the inside and outside of the fuel tank for communication between the inside and outside of the fuel tank. a valve case having a first valve seat; a second valve seat provided inside the fuel tank of the valve case, communicating with the intake passage and positioned approximately on the same center line as the first valve seat; , is in close contact with the first valve seat and is separated from the first valve seat when the internal pressure of the fuel tank exceeds a predetermined value, allowing air in the fuel tank to be discharged to the outside. an exhaust valve, and a relief valve that is in close contact with the second valve seat and allows air to flow from the outside into the fuel tank through the intake passage when the internal pressure of the fuel tank reaches a predetermined value or less. a seated valve provided in the key cylinder, and when the key is rotated, the seated valve is connected to the second seated valve.
A fuel tank cap comprising a cam body forcibly separated from a valve seat to establish communication between the inside and outside of the fuel tank.
