Abstract
A drawer device comprises a drawer and a frame. Either the drawer or the frame is provided with a rack extending in the direction of movement of the drawer, and the other is provided with a rotary damper, which inlcudes a spiral spring adapted to be wound from one end thereof as the drawer is pushed into an accommodation space in the frame, a locking member for locking the spiral spring against unwinding when the drawer is pushed into the accommodation space and a gear capable of being rotated in the forward and reverse directions under a braking force with the movement of the drawer. The gear and rack are coupled together. A bearing is provided between cooperating, relatively slidable surfaces of the drawer and frame.
