Claim 2:
3. The device according to claim 1, wherein the lock includes an active lever configured not to regulate an angle of rotation of the rotating cam in the first direction when the lock is in the locked state, and to regulate an angle of rotation of the rotating cam in the first direction to the predetermined angle when the lock is in the unlocked state, and
the electric releasing mechanism is configured to:
release meshing of the latch mechanism and return the rotating cam to the reference position by the biasing force of the spring, when the lock is in the locked state and the rotating cam rotates by a larger angle than the predetermined angle in the first direction from the reference position by power of the motor against the biasing force of the spring;
switch the lock from the locked state to the unlocked state and return the rotating cam to the reference position by the biasing force of the spring, when the lock is in the locked state and the rotating cam rotates in the second direction from the reference position by power of the motor against the biasing force of the spring; and
switch the lock from the unlocked state to the locked state and return the rotating cam to the reference position by the biasing force of the spring, when the lock is in the unlocked state and the rotating cam rotates by the predetermined angle in the first direction from the reference position by power of the motor against the biasing force of the spring.
