Claims

[Claims for Utility Model Registration] (1) A bracket whose one end is pivotally supported by a pin to a base plate and a spring is attached to apply tension between the bracket and the base plate, which is formed in a cylindrical shape and has a base thereof. It consists of a stationary side member whose end is fitted and fixed into a circular hole formed in the bracket, and a rotating side member that is attached via a bearing to the outer circumferential surface of the tip of this stationary side member. 1. A tensioner with a bracket for applying tension to a belt which is attached to a belt, wherein the bracket is made of synthetic resin and a pivot portion having at least a small circular hole through which the pin is inserted is formed with a thick wall. . (2) The tensioner with a bracket according to claim 1, wherein the fixed side member and the bracket are integrally joined during injection molding of the bracket. (3) The tensioner with a bracket according to claim 1 or 2 of the utility model registration claim, wherein the fitting portion of the stationary side member and the bracket is provided with means for preventing mutual rotation. (4) Any one of claims 1 to 3 of the claims for utility model registration, which is provided with means for preventing the stationary side member from slipping out of the fitting part at the fitting part between the stationary side member and the bracket. Tensioner with bracket as described in . (5) Any of claims 1 to 4 of the claims for utility model registration, in which the wall thickness of the pivot portion having a small circular hole at the end of the bracket through which the support pin is inserted is greater than the wall thickness of other parts. Tensioner with bracket described above.
