VALVE DEVICE FOR FUEL TANK

摘要

A valve body and a float body are combined by respectively coupling two or more coupling parts provided on one of the valve body and the float body to coupled parts provided on the other of the valve body and the flat body in a state allowing upward and downward movements of the valve body. During descent of the float body, one coupling part of the two or more coupling parts is caught on the coupled parts ahead of the other coupling parts whereby the valve body is tilted, and the other coupling parts restrict the tilting of the valve body.
