  • Driving-side pulley
    Patent number: 9228644
    Abstract: A driving-side pulley includes a cam mechanism that presses a movable sleeve in a first direction by utilizing a relative rotation of the movable sleeve in the normal direction with respect to an axis-line-direction fixed member, the first direction being a direction that has a pressing surface pressed against a corresponding side surface of a belt.

  • Driven-Side Pulley
    Publication number: 20140031155
    Abstract: The present invention provides a driven-side pulley including a fixed sheave supported by a driven shaft that is relatively rotatable around an axis line and immovable along the axis line, a movable sheave supported by the driven shaft that is relatively rotatable around the axis line and movable along the axis line, a spider supported by the driven shaft that is relatively non-rotatable around the axis line and immovable along the axis line, a biasing member that presses the movable sheave in a direction toward the fixed sheave, a main torque-cam 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.
