To provide a constitution in which a belt clamping pressure is fully produced in an operating stopping state of a belt-driven continuously variable transmission without adding other parts.

In the belt-driven continuously variable transmission, a stopper 34A extending toward a cylinder member 75 is integrally formed in a contact part for the cylinder member 75 in an outside cylinder 34f provided in a movable sieve 34b of a primary pulley 34. In the operation stopping state of the continuously variable transmission, the movable sieve 34b is pressed against the cylinder member 75 via the stopper 34A to turn the cylinder member 75 elastically deformed, so that the belt clamping pressure is produced using the repulsion.
