a slide pulley:
an endless annular member sandwiched by the fix pulley and the slide pulley;
a cylinder member which is fixed to the fix pulley, and which includes a cylinder cylindrical portion constituting a wall of a pulley pressure receiving chamber;
a restriction member configured to restrict an axial movement of the cylinder member; and
a stopper member disposed at a position at which the stopper member is abutted on the cylinder member when a hydraulic pressure which is equal to or greater than a predetermined value is supplied to the pulley pressure receiving chamber, provided radially outside the restriction member.
