<P>PROBLEM TO BE SOLVED: To realize a structure capable of preventing generation of a moment load with respect to an outer ring 7c and a pulley made of synthetic resin and arranged around the outer ring 7c and of effectively preventing creep generated between the outer ring 7c and the pulley while securing strength of the outer ring 7c. <P>SOLUTION: Two inclination grooves 14b, 14b inclined to different directions are formed on the outer peripheral face of the outer ring 7c. The inclination grooves 14b, 14b intersect with each other at their respective intermediate portions. Due to this construction, the generation of creep and the moment load is prevented. The inclination grooves 14b, 14b are formed so as to satisfy the conditions: h/D≥0.0072 and (a-b)/d≥0.343. Accordingly, the structure capable of effectively preventing the creep while securing the strength of the outer ring 7c is realized. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
