ンシヨナのリークダウン機構。[Claims for Utility Model Registration] A toothed belt in which a piston rod is fixed to a piston loosely fitted in a cylinder filled with oil, a spring applies a protruding force to the rod, and the protruding force applies tension to the toothed belt. In the tensioner for use, an O-ring or packing is interposed between the cylinder and the piston so that they do not come into direct contact with each other, and a leak-down flow path is provided on the O-ring, packing, or piston side to communicate the front chamber and the rear chamber of the piston. A leak-down mechanism for a toothed belt tensioner.
