    a belt wound around the one-side pulley and the other-side pulley; and

    an actuator,the one-side pulley including a moveable sheave member placed to be moveable relatively in an axial direction with respect to a fixed sheave fixed on a rotational shaft and that pinches the belt between the moveable sheave member and the fixed sheave, andthe actuator moving the moveable sheave member in the axial direction, whereinthe actuator comprises;

    a moveable feed member having an inner tube section supported to be rotatable around a center of the rotational shaft on a radially outer side of the moveable sheave member and in which a moveable-side feed screw is provided, an outer tube section placed around the inner tube section and in which an outer gear is provided on a radially outer side, and a lid section that connects the inner tube section and the outer tube section;

    a gear case having a fixed tube section in which a fixed-side feed screw that screw-engages the moveable-side feed screw is provided, and an outer cover integrally provided on the fixed tube section, in which an opening into which the outer tube section is inserted is formed, and that houses the outer gear; and

    an electric motor that drives a motor-side gear that intermeshes with the outer gear, andthe opening proximately opposes an outer circumferential surface on the side of the one-side pulley in relation to the outer gear on the outer tube section, in relation to the axial direction of the rotational shaft.
