とする無段変速機。[Claims for Utility Model Registration] A fixed pulley having a conical surface and fixed to the drive shaft, and a V-groove formed between the fixed pulley and the fixed pulley having a similar conical surface. a drive pulley that is movable in the axial direction of the drive shaft and is moved in a direction toward and away from the fixed pulley by a moving means; a fixed pulley that has a conical surface and is fixed to the driven shaft; It has a conical surface similar to this fixed pulley, forms a V-groove between it and the fixed pulley, is attached so as to be movable in the axial direction of the driven shaft, and is moved in a direction toward and away from the fixed pulley by a moving means. a driven pulley consisting of a movable pulley; each V of this driven pulley and the driving pulley;
Movement of the movable pulley on the drive pulley side or the driven pulley side in a V-belt type continuously variable transmission that has a V-belt wrapped around a groove and transmits the rotation of the drive shaft to the driven shaft in a stepless manner. a screw shaft fixedly provided along the outer periphery of the shaft on the opposite side to the conical surface of the movable pulley and having a male thread on the outer periphery; a screw rider which is provided on the screw shaft and is disposed facing the surface opposite to the conical surface of the movable pulley via a bearing so as to be able to move on the screw shaft; and a gear portion of the screw rider. In a continuously variable transmission constituted by meshed screw slider driving means, the screw slider is rotated by driving of the screw slider driving means, and the screw slider moves the movable pulley from the fixed pulley. A stopper means is provided to stop the movement of the screw slider at a predetermined position when the screw slider is moved on the screw shaft in the releasing direction, and the stopper means is provided to protrude from a surface of the screw slider opposite to the movable pulley. 1. A continuously variable transmission comprising: a stopper member; and a rod-shaped member protruding from the screw shaft toward the screw slider, the tip of which abuts on the stopper member.
