摘要： A pulley (1) for a continuously variable transmission is provided with a fixed half-pulley (10) fitted on a supporting shaft (5) and a mobile half-pulley (11), which is able to slide towards the fixed half-pulley (10) under the thrust of a spring (16), so as to define a V-shaped race (12) of variable amplitude. The pulley (1) is further provided with a device (28) for compensating the axial thrust, said device being constituted by a cam (22) and a com follower (30), which are coupled in contact with one another to impart an additional axial thrust on the mobile half-pulley (11) in response to a torque acting on the pulley (1). The cam (22) is defined by a tubular body (17) made of plastic material co-moulded on the supporting shaft (5), whilst the cam follower (30) is made of a single piece with the mobile half-pulley (11).
