ABSTRACT:
In a continuously variable transmission, a hydraulic actuator for axially moving a movable sheave has an outer cylinder which includes a radial portion extending radially from a boss on the stationary sheave. A bearing is disposed abutting the surface of the radial portion. The inner race of the bearing has a large diameter so that the inner race contacts at least a predetermined area of the surface of the radial portion, preferably, the entire area of that surface. One side of the inner race has a recess in which a nut for axially fixing the outer cylinder, the bearing and the like is disposed, thereby reducing the axial dimension of the continuously variable transmission.
