Continuously variable transmission

A continuously variable transmission comprising:

• an input pulley and an output pulley, each having a pair of pulley halves which have pulley faces and which form a V-groove;
• a rotating shaft which journals the input pulley or the output pulley;
• and
• an endless transmission member wound between the input pulley and the output pulley,
• wherein a gear ratio is changed by changing a width of the V-groove of the input pulley or the output pulley, and a driving force transmitted to the input pulley is transmitted to the output pulley through the endless transmission member,
• each of the input pulley and the output pulley is composed of a pair of pulley halves,
• the pulley halves of at least either the input pulley or the output pulley each has a first half element that is relatively rotatable with respect to the rotating shaft and a second half element that is slidable on a surface of the first half element between the first half element and the endless transmission member,
• the second half element is configured to rotate integrally with the rotating shaft serving as a center of rotation, and
• a size of the first half element in a radial direction is set to be equal to or more than a size of the second half element in the radial direction.
