Abstract: A belt-driven continuously variable transmission adapted to prevent a tilting motion of a sheave under high temperature. The belt-driven continuously variable transmission is comprised of a pair of pulleys individually comprised of a fixed sheave rotated integrally with a rotary shaft and a movable sheave fitted onto the rotary shaft while being allowed to reciprocate thereon, and a driving belt applied to the pulleys to transmit power therebetween. a stopper member is disposed on an outer circumferential side and in a side where the driving belt is not contacted with the movable sheave so as to prevent the movable sheave from being tilted to widen a width between the fixed sheave and the movable sheave holding the driving belt by a load from the driving belt.

Abstract: 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.

Abstract: A vehicle control device includes an engine that is a power source of a vehicle, a transmission configured to connect the engine to a drive wheel of the vehicle, and a clutch configured to connect or block transmission of power between the engine and the drive wheel through the transmission. The vehicle control device is capable of executing predetermined control to allow the vehicle to travel while stopping supplying fuel to the engine and releasing the clutch that has been engaged, during travel of the vehicle, and the vehicle control device downshifts the transmission at the time the clutch is released in the predetermined control. It is possible to shift the transmission into a lowest-speed side gear ratio by the downshift.

Abstract: 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).
