機のクラツチ構造。[Claims for Utility Model Registration] (1) A fixed shaft provided on at least one of a pair of rotating shafts arranged parallel to each other, and fixed to the one rotating shaft integrally and non-slidably. and a movable sheave that is rotatably and slidably supported on the rotating shaft and that forms a belt groove with a V-shaped cross section between it and the fixed sheave, and the movable sheave is fixed. This pulley-type continuously variable transmission is equipped with a speed change mechanism that changes the diameter of the pulley by moving it toward and away from the shaft, and by changing the pulley diameter of the variable pulley, the speed ratio between both rotating shafts can be changed from a low speed state to a high speed state. In the machine, a bearing having an outer race that cannot rotate with respect to the rotating shaft is rotatably mounted on the rotating shaft at the bottom of the belt groove between the two sheaves, and a bearing near the fixed sheave is attached to the outer periphery of the outer race of the bearing. A clutch structure for a pulley-type continuously variable transmission, characterized in that a ring is attached to the outer race, the ring being narrower than the width of the outer race and protruding from the outer peripheral surface of the outer race. (2) A ring groove is formed on the outer periphery of the outer race of the bearing near the fixed shaft of the variable pulley, and the ring is cut at one point in the circumferential direction, and is fitted into the ring groove and fixed to the outer race. A clutch structure for a pulley-type continuously variable transmission according to claim (1).
