A drawer device is provided in which a drawer can be locked and said lock released without the need for position control or motor stopping control. A lock frame 7 is actuated by engagement with a hook unit 521 being released by a DC motor 81 rotating in one direction in an engaged state; a drawer 2 moves forward when engagement with an anchor unit 72 is released by the lock frame 7 being actuated; a planetary gear unit 6 is pressed by the lock frame 7 by the lock frame being actuated; a small-diameter planetary gear 622 moves from the engaged state to an initial state by the planetary gear unit 6 being pushed by the lock frame 7; the anchor unit 72 engages with the drawer 2 when said drawer 2, advanced from the retracted position, is pushed back to the retracted position; and the hook unit 521 engages with the lock unit 71 when the drawer 2, advanced from the retracted position, is pushed back to the retracted position. |
