A tension arm, to which an idler pulley is rotatably attached at one end, is fixed to a fixed part that fixes the autotensioner to another member so as to be able to swing, and between the two In an auto-tensioner in which a spring is disposed in the tension arm to bias the tension arm in one direction, the fixing member and the tension arm partially overlap each other in an annular shape to form an overlapping part, and the overlapping part A notch is provided in at least one overlapping surface, and the space formed by the notch and the other overlapping surface is annular, has elasticity, and has a hardness of JI.
An auto tensioner characterized in that a friction member of S HS 65 to 95 is inserted in a compressed state. 2. The auto-tensioner according to claim 1, wherein the fixing member and the tension arm each have bowl-shaped portions facing each other, and ends of the bowl-shaped portions are overlapped to form an overlapping portion. Jonah. 3. The fixing member has a tensioner shaft, and the tension arm has a cylindrical part, and the cylindrical part is coaxially inserted into the tensioner shaft, and the two form an overlapping part. The autotensioner according to claim 1, characterized in that:
