1. A continuously variable transmission comprising, in a case:
a drive pulley and a driven pulley each including a fixed-side pulley half and a movable-side pulley half configured to move axially relative to the fixed-side pulley half;
a belt including a plurality of elements and a plurality of rings wound around the drive pulley and the driven pulley;
a parking gear provided to the fixed-side pulley half of the driven pulley; and
a parking pawl configured to be fitted to the parking gear by swinging,
the continuously variable transmission transmitting a driving force from a drive source to a wheel while changing a transmission ratio by changing groove widths of the drive pulley and the driven pulley, wherein
the case includes an annular rib integrally molded with the case in a manner surrounding an outer periphery of the parking gear except for a position intersecting a swing trajectory of the parking pawl and a predetermined position.
