The present invention provides a driven-side pulley including a fixed sheave that is supported by a driven shaft so as to be relatively rotatable around an axis line and immovable along the axis line, a movable sheave that is supported by the driven shaft so as to be relatively rotatable around the axis line and movable along the axis line, a spider that is supported by the driven shaft so as to be relatively non-rotatable around the axis line and immovable along the axis line, and a biasing member that presses the movable sheave in such a direction as that the movable sheave comes closer to the fixed sheave, the driven-side pulley further including a main torquecam mechanism that presses the movable sheave in the axis line in accordance with a relative difference in a rotational angle between the spider and the movable sheave, and a sub torque-cam mechanism that presses the movable sheave in the axis line in accordance with a relative difference in a rotational angle between the fixed sheave and the movable sheave. |
