ABSTRACT:
In association with a solenoidal coil10being energized to unlock a shift lever1C, a first movable core9and a second movable core11magnetically stick together so as to rotationally move in unison from an original position in which the first movable core9engages with the second movable core11. Because the first movable core9and the second movable core11stick together before unlocking the shift lever1C, it is possible to avoid the first movable core9from hitting the second movable core11so as to eliminate an operational noise. A lock plate7and a link plate8are rotatably provided around a rotational center6in relative to the solenoidal coal10. This prevents the lock plate7and the link plate8from moving rotationally in unison with the solenoidal coil10so as to insure a smooth and quick rotational movement.
