PROBLEM TO BE SOLVED: To prevent the generation of twist in a coil spring, and to prevent the generation of waving phenomenon in a driven pulley device for a V-belt type automatic transmission, which is provided with a fixed pulley half body fixed to an inner cylinder, a movable pulley half body fixed to an outer cylinder capable of relatively turning and relatively moving in the axial direction in relation to the inner cylinder, a torque cam mechanism provided between the inner cylinder and the outer cylinder, a spring receiver member fixed to the outer cylinder, and a coil spring for surrounding the outer periphery and provided to be shrunken between the movable pulley half body and the spring receiver member and in which a V-belt for transmitting rotating power from a driving pulley device is pinched between opposite conical surfaces of the fixed pulley half body and the movable pulley half body. SOLUTION: The coil spring 93 is guided by a guide member 106 in the inner periphery thereof on a movable pulley half body 90 side thereof, and a thrust bearing means 107 is interposed between the spring receiver member 92 and the coil spring 93.
