るオートテンシヨナ。 A body integrally formed with a lower body and an upper body screwed to the inner peripheral surface of a flange formed in the opening thereof, and slidably inserted into the inner peripheral sliding surface of the lower body. a hollow plunger that forms a second pressure chamber between it and the lower body; a spring that always biases the plunger toward the second pressure chamber; the plunger is slidably inserted into the plunger; a rod that protrudes from the upper body and forms a first pressure chamber with its lower end and the plunger; a hole drilled in the side wall of the plunger that communicates with the first pressure chamber; and oil only from the second pressure chamber to the first pressure chamber. What is claimed is: 1. An autotensioner having a check valve that allows a flow of water to flow, characterized in that a thin wall portion is formed in the flange portion between the sliding surface of the lower body and the female threaded portion of the flange in the circumferential direction.
