<p>PROBLEM TO BE SOLVED: To suppress switching of the lock state of a power supply plug unintended by a user, in a power supply plug lock system.SOLUTION: A power supply plug 10 is provided with a plurality (four in the example) of contact sensors 58a-58d. When a user simply touches any one of the plurality of contact sensors 58a-58d, for example, a lock ECU 77 does not determine that the user is gripping the power supply plug 10, which is thereby not switched to unlock state. Consequently, switching of the lock state of the power supply plug 10, unintended by a user, can be suppressed.</p> |
