ABSTRACT:
A tank cap has outstanding operability when the fuel cap opens and closes a tank opening of a fuel tank. The tank cap is provided with a casing main body, a cover body provided with an handle and a torque mechanism. The torque mechanism transmits rotational torque to the casing main body when rotational torque is applied to the handle. A torque release mechanism is also disposed between the handle and a torque plate of the torque mechanism. A torque release mechanism is provided with a steel ball (interposing member) which is in a non-interposed state between the handle and the casing main body when affected by a predetermined or greater inertial force accompanying an external force and the steel ball sets the handle in an idle state when the torque release mechanism is in a non-interposed state.
