Abstract: A drawer apparatus capable of locking and unlocking a drawer without position control and motor stop control is provided. A lock frame is released from the hook to be brought into an operable state by unidirectional rotation of a DC motor in an engaged state. A drawer is released from an anchor to be advanced out of the retracted position when the lock frame operates. A planetary gear unit is pushed by the lock frame. A small-diameter planetary gear is thereby shifted from the engaged state to a default state. The anchor is engaged with the drawer when the advanced drawer is pushed back to the retracted position. The hook is engaged with a lock when the advanced drawer is pushed back to the retracted position.
