To transmit larger torque without reducing a characteristic of a rheology liquid over a long period by pressing an electric or magnetic rheology liquid by passing it through a clearance of an electrode or a magnet by a surface means acting as a piston.
When housings 2 and 3 composed of an insulating material are rotatary driven, for example, in the arrow 11 direction, due to frictional force applied to an electric rheology liquid by a horizontal directional boundary surface of a disc-shaped chamber 8, pressure is applied to a rear spoke 12 in the rotational direction, and rotates a disc 10 having a spoke composed of an insulating material and a shaft 1 fixed to this. Viscosity of the electric rheology liquid is increased by impressing high voltage on an electrode 5 through a sliding contact piece 6 and a connecting lead wire 7 from a high voltage source, and pressure on the spoke also increases thereby, and carrier liquid inside particles are permanently redispersed, and transmission torque can be continuously controlled through an electric field.
