Auto Tensioner
Abstract: An automatic tensioner includes a base, a rotary member which is supported, rotatably on the base and to which a pulley around which a belt is wound can be attached, a coil spring including one end locked on the base and the other end locked on the rotary member and adapted to bias the rotary member in one direction with respect to the base, an elastic element including one end locked on one of the rotary member and the base and the other end which is a free end and extending along an inner circumferential surface of the other of the rotary member and the base, and a friction member connected so as to be brought into contact with the inner circumferential surface of the other of the rotary member arid the base and so as not to move in a circumferential direction relatively to the elastic element, wherein the coil spring is disposed in such a state that the coil spring is compressed in an axial direction and the friction member is pressed against the one of the rotary member and the base by a repulsive force attempting to expand in an axial direction.
