るオートテンシヨナ装置。 A bracket is disposed on the side of the belt of the belt transmission mechanism and has its base end swingably attached to the engine body, and the bracket is rotatably supported by the swinging end of the bracket and is pressed against the belt. They each include an idler pulley and a damper that presses the bracket in the tension direction of the belt, and the damper includes a piston slidably inserted into the cylinder, and a damper attached to one end of the piston that presses the bracket in the tension direction of the belt. a piston rod whose top portion protruding toward the side contacts the bracket; and a high oil pressure chamber formed between the other end of the piston and the inner wall surface of the cylinder, and the other end of the piston on the high oil pressure chamber side. The auto tensioner device is specially designed to have a pressure-receiving surface that uses hydraulic pressure to offset the rotational moment of the piston caused by the lateral force transmitted from the belt side.
