    • A belt-driven continuously variable transmission having a downsized torque cam assembly for creating forward thrust to push a movable sheave toward a fixed sheave.The belt-driven continuously variable transmission is adapted to output a torque while changing a speed ratio continuously by altering an effective diameter position of a driving belt. The belt-driven continuously variable transmission is comprised of: an output gear, which is fitted onto the rotary shaft of the driven pulley to output the torque while being allowed to rotate relatively; a piston, which is fitted onto the rotary shaft of the driven pulley between the movable sheave and the output gear while being allowed to rotate integrally with the movable sheave and to reciprocate in an axial direction of the rotary shaft, and which increases an internal pressure of the hydraulic chamber by moving toward the movable sheave; and a torque cam assembly, which is interposed between the piston and the output gear, and which pushes the piston toward the movable sheave when the torque transmitted through the driven pulley is increased.

    • In a fluid coupling wherein a turbine shell is welded to a turbine hub, it is necessary to take care of the strength of the welded portion because the turbine shell is displaced toward the pump blade as the torque thereof is transmitted. A fluid coupling (10) according to the present invention is provided with an input-side rotary constituent (A) including a pump blade (18), to which is attached an input member, and an output-side rotary constituent (B) including a turbine shell (22), to which is attached a turbine blade (21) opposed to the pump blade (18), and a turbine hub, to which is coupled an output member (1), the turbine hub (15) being welded to an inner peripheral portion of the turbine shell (22), wherein the turbine shell (22) and the turbine hub (15) have contact surfaces (23, 24), respectively, extending along a rotational axis (10a) of the fluid coupling (10), and a joint portion (14) is formed by the welding on the contact surfaces (23, 24) closer to the pump blade (18).
