るコイルスプリング取付装置。 A belt in which a fixed sheave and a movable sheave form an expandable and contractible belt winding groove, and a coil spring is interposed between the outer surface of the movable sheave and a spring bearing member provided on a shaft that rotates integrally with the fixed sheave. In the continuously variable transmission, approximately one turn of an end turn portion having a diameter larger or smaller than other effective winding portions is formed at the free end of the coil spring, and a bent portion is formed at the tip of the end turn portion. On the other hand, on the outer surface of the movable sheave and the spring receiving member, a spring seat surface that is in close contact with the outer periphery or inner periphery of the end turn portion at more than half the circumference, and a locking portion that locks the bent portion are formed. A coil spring mounting device characterized by:
