POWER SUPPLYING PLUG LOCK DEVICE

摘要

A power supplying plug lock device attachable to an operation arm of a power supplying plug, the operation arm operable to fix the power supplying plug to an inlet, is configured to restrict movement of the operation arm to prevent unauthorized removal of the power supplying plug. The power supplying plug lock device is externally attachable to the operation arm when an authentication member accomplishes authentication. A restriction member moves from an open position to a close position to engage with the operation arm when the power supplying plug lock device is attached to the operation arm. A position holding mechanism shifts to a lock state in cooperation with the movement of the restriction member to the close position, thereby holding the restriction member at the close position. The position holding mechanism maintains the lock state until the authentication member again accomplishes authentication.
