Abstract: An automatic transmission is provided, which includes a variator having a first pulley, a second pulley and a belt wound around the first and second pulleys, a first motor configured to give a pulley thrust force for shifting the variator to the first or second pulley, a second motor configured to cause a belt clamping force to be generated in the variator, and a power transmission mechanism provided between the second motor and the variator, to transmit an output torque of the second motor to the variator. The power transmission mechanism includes a cycloid decelerator configured to decelerate an input torque from the second motor, and transmit the decelerated input torque to the variator.

Abstract: A pulley propulsion device for an automatic transmission, which includes a fixed pulley, and a movable pulley constituted capable of relative displacement along a rotation axis of a pulley with respect to the fixed pulley, is provided. The pulley propulsion device includes a movable member constituted capable of relative rotation around a rotation axis of the pulley with respect to the movable pulley, a fixed member whose rotation with respect to a pulley case is regulated and adapted to give linear displacement to the movable member along the rotation axis of the pulley on the basis of rotation thereof, a driving mechanism having an electric motor and adapted to cause an output torque of the electric motor to be transmitted to the movable member and to cause the movable pulley to generate a predetermined pulley thrust, and a load sensor adapted to detect a load applied on the fixed member.

Abstract: A differential unit (102) is provided with a ring gear (10) that meshes with an output gear (21) of a transmission (101), an axle shaft (105) that is connected to front wheels, and a drive gear (11) that is fixed by screws to a plurality of boss portions (3e) and spaced apart from the ring gear (10). A transfer unit (103) disposed rearward of the differential unit (102) is provided with a driven gear (20) that meshes with the drive gear (11). Drive force is transmitted from the driven gear (20) to a propeller shaft (104), and the propeller shaft (104) transmits the drive force to rear wheels. First material-removed portions (12) made of concave portions are formed in an inner circumference of a portion of a case (1) to which the axle shaft (105) is mounted. Second material-removed portions (13) made of concave portions that extend in an axial direction of the axle shaft (105) are formed between the plurality of boss portions (3e).

Abstract: A differential case (2) comprises a hollow shaft (2b) for transmitting the rotation of an output gear of a transmission to a transfer and houses a pair of pinions (4) and a pair of side gears (7R, 7L) which mesh with the pinions (4). The side gears (7R, 7L) comprising sleeves (8) which engage with front wheel axle shafts (101R, 101L). Plugs (12) which seal the sleeves (8) of the side gears (7R, 7L), a first oil seal (13) disposed between the hollow shaft (2b) and the sleeve (8) of one of the side gears (7R), a second oil seal (14) disposed between the hollow shaft (2b) and the differential housing (10), and a third oil seal (15) disposed between the differential housing (10) and the sleeve (8) of the other side gear (7L), stop oil filled in the differential casing (10) and differential housing (2) from flowing out.
