    摘要： A torque generation apparatus of the present invention suitable for size reduction and capable of providing a large shearing force includes a magnetic viscous fluid placed between a magnetic disc and a first yoke and a second yoke, a coil disposed so as to overlap with the magnetic disc as viewed in a direction along a first direction, and a third yoke that constitutes a magnetic path of a magnetic field generated by the coil together with the first yoke and the second yoke. The magnetic disc includes a torque increasing portion at at least one of a surface facing the first yoke and a surface facing the second yoke. The torque increasing portion is provided in an outer circumferential area of the magnetic disc in a second direction, which is a radial direction perpendicular to the first direction, and causes a shearing force to a cluster of the magnetic viscous fluid to become larger than that in an inner circumferential area inside the outer circumferential area. The third yoke has a magnetic gap with the first yoke. The magnetic gap is formed at a position outside the outer circumferential edge of the magnetic disc or overlapping with the outer circumferential edge of the magnetic disc as viewed along the first direction.

    摘要： A magneto rheological damper (20) includes a housing (22) extending between a first opened end (24) and a second opened end (26) and defining a fluid chamber (28, 30) extending therebetween. An end cap (32) is located at the first opened end (26) and coupled to the housing (22). A piston (36) is disposed in the fluid chamber (28, 30) dividing the fluid chamber (28, 30) into a compression chamber (28) and a rebound chamber (30). A piston rod (44) extends along the center axis (A) and attaches to the piston (36) for movement with the piston (36) between a compression and a rebound stroke. A magnetic field generator (56) is located in the compression chamber (28) and in an abutment relationship with the end cap (32). An extension portion (80) protrudes radially outwardly from the housing (22) and defining a compensation chamber (86) and a channel (90). The channel (90) is in fluid communication with the compression chamber (28) and the compensation chamber (86) for allowing the working fluid to flow from the compression chamber (28) to the compensation chamber (86).
