Patent ID: 7658297

Claim:
A fuel cap comprising: a closer that seals a tank opening and that has a cap engagement element that is engaged by an opening engagement element of the tank opening when the closer is rotated by a preset angle; a handle mechanism that is attached to an upper portion of the closer in a rotatable manner to rotate the closer in either of a closing direction and an opening direction of the tank opening; and a torque mechanism that includes a body interlocking portion formed on an upper portion of the closer, a torque plate having a torque main body interposed between the handle mechanism and the closer, and resilient torque pieces formed on the torque main body, the torque mechanism being configured to transmit a rotational torque applied to the handle mechanism to the closer via the torque plate, wherein the resilient torque pieces are formed as an arcuate cantilever protruded from the torque plate body with a space between the resilient torque pieces and the torque plate body, and have a first end as a supporting terminal portion connected with the torque plate body, a second end as a free end of the resilient torque pieces, and a torque piece interlocking portion disposed between the first end and the second end, the torque mechanism is configured such that pressing of the torque piece interlocking portion against the body interlocking portion deforms the resilient torque pieces to narrow the space in a state which the second end is in contact with the torque plate body, and the torque piece interlocking portion rides over the body interlocking portion when the rotational torque exceeds a predetermined level.
