Abstract:
A cap device comprising a cap configured to open and close a tank opening, the cap comprising:a closer for closing the tank opening with air-tight sealing at a closing position; a handle mechanism having a handle, the handle being switchable between a handling position and a retracted position, the handling position being a position allowing a user to operate the handle to open and close the closer, the retracted position being a position in which the tank opening is closed, the handle in the handling position being configured to project outwardly from an upper portion of the closer a greater distance than the handle is in the retracted position; and an interconnecting mechanism, provided between the handle mechanism and the closer, for transmitting to the closer rotational torque in a closing direction and opening direction when the rotational torque is applied to the handle mechanism, wherein the interconnecting mechanism comprises a clutch mechanism, the clutch mechanism setting the interconnecting mechanism in a transmission mode and a non-transmission mode, the transmission mode being a mode wherein the rotational torque in the closing direction and the opening direction is transmitted from the handle to the closer when the handle is placed in the handling position, the non-transmission mode being mode wherein the rotational torque in the opening direction is prevented from transmitting from the handle to the closer and the handle mechanism rotates freely in the opening direction when the handle is placed in the retracted position.
