To obtain linear characteristics between transmittable torque and differential speed between the two rotary members in the viscous coupling apparatus including a working chamber filled with a viscous fluid and first and second plural annular resistance plates fixed to the first and second rotary members, respectively, at least one of the annular resistance plates is formed with plural blades to agitate the viscous fluid within the working chamber. The blades can be formed by forming a plurality of cutouts in the annular resistance plate in the vortical arrangement manner and then bending the edge of each cutout therealong. |
