<p><P>PROBLEM TO BE SOLVED: To provide a V-belt type continuously variable transmission preventing the loosening of a bearing rotatably supporting a drive shaft. <P>SOLUTION: The V-belt type continuously variable transmission is comprised of a drive pulley 16 and a driven pulley 26 provided with pairs of fast pulleys 18, 30, respectively, and movable pulleys 22, 34, and a V-belt 1 suspended between the drive pulley and the driven pulley. Bearings 88a, 88b are provided for rotatably supporting both ends of the drive shaft 14 transmitting rotation from a drive source to the fast pulley, and a portion for press-fitting the bearing of the drive shaft is tapered so that a diameter becomes smaller as it is separated from the fast pulley 18. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
