Claims

[Claims for Utility Model Registration] A V-groove is formed between a fixed pulley having a conical surface and fixed to the input shaft, and a fixed pulley having a conical surface similar to this fixed pulley. a drive pulley consisting of a movable pulley that is movably attached in the axial direction of the input shaft and is moved in a direction toward and away from the fixed pulley by a moving means; a fixed pulley having a conical surface and fixed to the output shaft;
This movable pulley has a conical surface similar to that of the fixed pulley, and is attached movably in the axial direction of the output shaft by forming a V-groove between it and the fixed pulley, and is moved in a direction toward and away from the fixed pulley by a moving means. The V-belt type stepless type has a driven pulley consisting of a pulley and a V-belt wrapped around each V-groove of the driven pulley and the drive pulley, and transmits the rotation of the input shaft to the output shaft by changing the speed of the input shaft steplessly. In a transmission, between a cam drum move fixed to a movable pulley on the driven pulley side and a drum fixture rotating together with the fixed pulley, a sudden relative rotation occurs between the cam drum move and the drum fixture. A pulley structure for a V-belt type continuously variable transmission characterized by forming a space that is compressed between the two and acts as a buffer when the two are moved.
