摘要： A spline (3) is fit on a rotary shaft (1) at a position bounding a first diameter (D1) passing through an axis of the rotary shaft (1), located between a backside inner circumferential surface of a movable pulley disk (4) and a first outer circumferential surface (1a) of the rotary shaft (1), and arranged to restrict rotation of the movable pulley disk (4). A hydraulic fluid chamber (5) for driving the movable pulley disk (4) is formed at a backside position of the movable pulley disk (4). A seal portion (6) for the hydraulic fluid chamber (5) is fit over the rotary shaft (1) at a position bounding a second diameter (D2) passing through the axis of the rotary shaft (1), located at a gap between a sheave-side inner circumferential surface of the movable pulley disk (4) and a second outer circumferential surface (1b) of the rotary shaft confronting the sheave-side inner circumferential surface. The second diameter (D2) is set equal to the first diameter (D1).

摘要： A continuously variable transmission includes a primary pulley (1)having a primary movable sheave (13) that is capable of moving to change a groove width of the primary pulley (1), and a secondary pulley (2) having a secondary movable sheave (23) that is capable of moving to change a groove width of the secondary pulley (2). Endless flexible members (3) are engaged with the primary pulley (1) and the secondary pulley (2) to transmit torque therebetween. At least one of the pulleys (1; 2) has a thrust applying mechanism (14, 15, 16, 17a, 17b, 18; 24, 25, 26, 27a, 27b, 28) that is capable of applying spring force and first fluid pressure force to the movable sheave (13; 23) of the pulley (1; 2) so as to narrow the groove width thereof and generating second fluid pressure force opposite to the spring force and the first fluid pressure force.
