オートテンシヨナ。 A nut having a piston rod at one end, a bolt rotatably screwed into the nut, a bottomed cylindrical body into which the nut is slidably inserted, and a cylindrical body fitted between the bottom of the body and the bolt. The belt auto-tensioning system is made up of a tension-setting spring fitted onto the bolt and a tension setting spring that is connected to an idler pulley that engages with the belt that transmits the power of the engine, and that uses the spring to apply tension to the belt. In the case, a stopper for preventing the piston rod from coming out is installed in a circumferential groove formed on the outer peripheral surface of the open end of the body, and a pin having a spherical end is inserted into the through hole formed in the bottom of the body with the bolt. The belt is characterized in that the pin is provided with a sealing member that faces the end face of the pin, has the other end slightly protruding from the body, and prevents leakage of lubricating oil sealed inside the body. auto tensioner.
