ABSTRACT:
A V-pulley to be used in a belt type continuously variable transmission, which V-pulley comprises a stationary pulley half fixedly mounted to a transmission shaft and a movable pulley half coupled slidably to the shaft via a plurality of rows of ball keys and cooperating with the stationary half to support a V-belt. A plurality of coil springs resiliently biasing the movable half toward the stationary half too impart an initial tension to the V-belt. A hydraulic operating device includes a first hydraulic member fixedly mounted to the shaft and a second hydraulic member disposed on the movable pulley half to define a hydraulic chamber against the first member for operating the movable half by hydraulic pressure fed to the hydraulic chamber. A control valve for controlling the pressure supply to the device. A plurality of guide grooves are provided on the outer periphery of the shaft for guiding the rows of ball keys and the coil springs are disposed at positions between the guide grooves This serves to avoid interference of the springs with the ball keys and the hydraulic device.
