Claims

[Claims for Utility Model Registration] (1) A drive side pulley that guides oil supplied into the crankshaft into and out of the power piston chamber in the slide pulley and moves the slide pulley in the axial direction, and a The driven pulley is rotatably supported by a bearing around a mounting bolt, and has a male spline on its outer periphery and a spring receiver cylinder provided in series with a sliding shaft. , a fixed sheave that is rotatably attached to the mounting bolt via a bearing and has a cylindrical portion that fits onto the outer periphery of the tip end of the spring receiver cylinder; and a cylinder that slides on the sliding shaft and the cylindrical portion. a moving sheave having a hole and a female spline having a small axial dimension that engages with the male spline, and having seal members disposed at both ends in the axial direction in contact with the cylindrical portion and the sliding shaft, respectively; A continuously variable transmission characterized in that a lubricant passage is formed in a female spline. (2) The continuously variable transmission according to claim 1, wherein the lubricant passage is constructed by reducing the diameter of the top of the male spline and/or the female spline. (3) The continuously variable transmission device according to claim 1, wherein the lubricant passage is constructed by cutting out a required number of male splines and/or female splines.
