PURPOSE:To minimize a temperature effect and enable braking almost constantly at all times in a damper for controlling an open and close mechanism for an ash tray and the like in an automobile by pressing the peripheral surfaces of a cylindrical part and an axial part for contact via an energizing member and braking a rotational force from a driving source with a frictional force between the cylindrical part and the axial part. CONSTITUTION:A damper 100 is constituted with a cylindrical part 1, an axial part 2 inserted in the cylindrical part 1, and a coil spring 3 as an energizing member. A pinion gear 20 is integrated with one end of the axial part 2. In addition, two slits 10 are formed in the cylindrical part 1 at positions opposite to each other about a center axis. The internal surface of the cylindrical part 1 and the external surface of the axial part 2 are pressed to each other with the energizing force of the coil spring 5. According to the aforesaid construction, braking is mechanically made without any use of oil and consequently a temperature effect is so small that braking can be made almost constantly at all times. |
