Abstract
A lock device can be shifted between a locked state and an unlocked state. The lock device includes a lock pin, a solenoid, and a pressing unit. The lock pin is movable between a locked position where a propeller is locked and an unlocked position where the propeller is not locked. The pressing unit presses the lock pin to the locked position by a mechanical pressing force. The solenoid includes a solenoid coil and a plunger. When the solenoid coil is energized, the plunger moves the lock pin to the unlocked position against the mechanical pressing force.
