PROBLEM TO BE SOLVED: To reduce bearing pressure acting on a torque transmission surface between a pulley shaft and a movable pulley. SOLUTION: A V-belt type continuously variable transmission includes a groove width variable mechanism 80 for changing a groove width of a pulley 60 by sliding the movable pulley 62 along a support part 51b in the pulley shaft 51, and includes a torque transmission part 110 relatively nonrotatably arranged to the pulley shaft, a boss part 63 arranged in the movable pulley 62 and transmitting torque between the torque transmission part 110 and itself, a flange part 111 arranged in the torque transmission part 110 and extending in the radial direction of the pulley shaft, and an axial directional part 112 integrally arranged in the flange part 111. The axial directional part 112 is positioned outside in the radial direction more than an opposed surface 63a with the support part 51b of the movable pulley 62. A synthetic resin shock absorbing member 66 is arranged between the axial directional part 112 and the torque transmission surface in the boss part 63. COPYRIGHT: (C)2010,JPO&INPIT
