Belt type continuously variable transmission

A belt type continuously variable transmission comprising:

• a drive pulley (13) including a movable side pulley half (17) that is openable and closable in an axial direction with respect to a fixed side pulley half (16);
• a driven pulley (14) including a movable side pulley half (23) that is openable and closable in an axial direction with respect to a fixed side pulley half (22);
• and
• a metal belt (15) that is wound around the drive pulley (13) and the driven pulley (14),
• wherein a change gear ratio is changed between LOW and OD by changing groove widths of the drive pulley (13) and the driven pulley (14) with hydraulic pressure, and
• wherein, in the LOW change gear ratio, the movable side pulley half (17) of the drive pulley (13) is not confined in the axial direction, and the movable side pulley half (23) of the driven pulley (14) abuts a closing stopper (30) to regulate movement in a closing direction, and
• in the OD change gear ratio, the movable side pulley half (17) of the drive pulley (13) is not confined in the axial direction, and the movable side pulley half (23) of the driven pulley (14) abuts an opening stopper (31) to regulate movement in an opening direction.
