Claims

[Claims for Utility Model Registration] (1) The inner peripheral surface has a female thread that is screwed into the male thread of the slider shaft, and the movable pulley moves toward and away from the fixed pulley by moving along the slider shaft. The slider is a slider that can be moved in the direction, and bearings are provided at both ends of the inner circumferential surface of the slider so as to come into contact with the outer periphery of the male screw of the slider shaft and can prevent the slider from wobbling with respect to the slider shaft. The slider structure of a continuously variable transmission is characterized by the following: (2) A utility model characterized in that the male thread of the slider shaft is a square thread or a trapezoidal thread, and bearing portions that can come into surface contact with the outer periphery of the male thread are formed on both ends of the female thread of the slider. A slider structure for a continuously variable transmission according to claim 1.
