Summary:PURPOSE:To eliminate delay of torque transmission and improve responsiveness by providing extremely thin blades spread radially with specified angles and reinforcing ribs on one of two shafts housed between a piston and a housing. CONSTITUTION:A rotor 41 is provided on one of two shafts housed in a hollow portion wherein highly viscous fluid is sealed, and formed between a piston and a housing. The rotor 41 is spline-fitted to an outer periphery of a rotary shaft 22, while a plurality of blades 42 are integrated therewith so as to extend in a radial direction. The blades 42 extending radially with specified angles, have extremely thin thickness in a circumferencial direction. Reinforcing ribs 46 are arranged between the blades 42, 42. When the rotor 41 is relatively rotated, a highly viscous fluid 45 in a pressure chamber 44 is forcibly moved. At this time, it moves in a short period because the circumferencial length between the blades 42, 42 is short, and responsiveness of torque transmission is satisfactory. The blades have extremely thin widths due to the reinforcing ribs to secure an adequate volume of the pressure chamber.
