<p>The present invention is directed to reducing wear to the mounting holes of the resin-made chain guide of the chain guide assembly. The chain guide assembly 1 includes a resin-made chain guide 10 that has a chain sliding surface 10a on which a chain travels and that has a plurality of mounting holes 11, 12 formed thereinto, and mounting bolts 2, 3 that are inserted into the mounting holes 11, 12. One of the mounting holes 11, 12 is an elongated hole, and a rotatable collar 4 is fitted around the outer periphery of the shaft portion 3a of the mounting bolt 3 that is inserted into the elongated hole 12. When the chain guide 10 deforms in the longitudinal direction, the outer peripheral surface of the collar 4 rolls on the inner wall surface 12u on the upper side of the elongated hole 12.</p> |
