Abstract: A lock device that restricts removal of an engaging member from an engaged member includes a cover attachable to the engaging member. The cover is moved between a position covering an operation portion and a position exposing the operation portion when external force is applied to the cover. A holding unit holds the cover at the position covering the operation portion. An authentication portion releases the cover from the holding unit when authentication is accomplished.

Abstract: 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.

Abstract: A vehicle starter switch device including a cylinder, a rotor rotatable in the cylinder to a plurality of rotational positions including a first position and a second position, an ignition switch connected to the rotor, and a restriction mechanism that restricts and permits the rotation of the rotor. The restriction mechanism includes a single solenoid that restricts rotation of the rotor from the first position to the second position when de-energized. The solenoid also permits rotation of the rotor from the second position to the first position when de-energized.
