Abstract: A door lock device includes a latch projecting from the side surface of the door, and a hook supported opposite to the latch in a doorjamb such that the hook can turn between a latch detaining position and a latch releasing position. A hook control member turns between a hook detaining position at a locking position and a hook releasing position. First, second and third rocking plates are interlocked with the hook control member. When a solenoid actuator rod engaging with the third rocking plate projects upward to fasten the door lock device, the third rocking plate is turned clockwise by a pin, and the second rocking plate having a pin pressed against the third rocking plate turns clockwise. Conversely, when the rod is retracted the door lock device is unfastened.
