PROBLEM TO BE SOLVED: To provide a structure allowing a diameter of a bearing to be reduced, in a V-belt continuously variable transmission.SOLUTION: A movable sheave 30 can be divided into a first sheave half body 81 having a cam face 32 and a second sheave half body 83 having a belt receiving surface 82. A boss 85 having a diameter larger than that of a crankshaft 21 and smaller than that of the first sheave half body 81 is provided to the second sheave half body 83. A bearing 41 is fitted to the boss 85. So far, a large-diameter bearing has been fitted to the outer peripheral surface of the movable sheave 30. The bearing 41 is fitted to the boss 85. Consequently, the bearing 41 can be remarkably reduced in diameter. |
