[Action]

 In order to put the door lock mechanism (10) into the deadlock state, it is necessary to operate the deadlock operating condition switch from outside the vehicle. Deadlock operating condition When the switch is operated, a signal for deadlock operating condition is output. In addition, for example, it is necessary to output a signal for deadlock operation by a wireless transmitter.

When the deadlock operating condition signal is output and the deadlock operating signal is output, the control unit (50) controls the operating unit (31) to control the deadlock mechanism ( 30) is operated to the restraining position, and the door lock mechanism (10) is restrained in the unlocking operation incapable.

That is, the door lock mechanism (10) cannot be put into the deadlock state until two signals are output by different operations in addition to the necessity of operating from the outside of the vehicle. As a result, there is no possibility of accidentally or unknowingly operating the wireless transmitter to enter the deadlock state not only from the inside of the vehicle but also from outside the vehicle.
