る内燃機関のベルトテンシヨナ構造。 A belt for an internal combustion engine that has a tensioner pulley that is pressed by a timing belt on one end of an arm that is swingably supported, a contact part on the other end, and a hydraulic autotensioner that presses this contact part. In the tensioner structure, the auto tensioner is formed of a main body, a pressing rod, and a mounting plate having a plurality of bolt holes, and the tip of the pressing rod has a spherical shape. A recess that matches the shape of the tip of the pressing rod is formed in the abutment portion, and an assembly auxiliary portion is provided at the lower part of the main body, and the assembly auxiliary portion allows the auto tensioner to be tightened around the pressing rod. 1. A belt tensioner structure for an internal combustion engine, characterized in that a bolt hole portion is deformed so as to rotate the auto tensioner and move the auto tensioner toward a contact portion side.
