PURPOSE: To allow the remote control of a lid lock device by providing a receiver device on an actuator for moving a control lever to lock and unlock positions, and transmitting an unlock signal thereto by a determined code signal.

CONSTITUTION: A lock device 50 is formed of a frame 11, a handle 13, a key cylinder 14, a latch 15, an energizing spring 16, a control lever 17, and a solenoid 60. The control lever 17 is movable to lock and unlock positions by the rotation of the key cylinder 14. The solenoid 60 is provided on the frame 11, connected to the control lever 17 by a plunger 61. When the solenoid 60 is energized, the plunger 61 is attracted to the solenoid 60 to move the lever 17 to the unlock position. The receiver device is provided on the solenoid 60, and the unlock signal of a determined code signal is transmitted thereto to conduct unlocking. Thus, the remote control can be performed.
