PROBLEM TO BE SOLVED: To provide a manufacturing method for a viscous coupling for improving management precision of torque transmission performance by corresponding to dimensional precision of parts related to transmission of torque and temperature of use environment of the viscous coupling. SOLUTION: In this manufacturing method for the viscous coupling for preparing the viscous coupling having a first rotary member having a plurality of first torque transmission members, a second rotary member arranged so as to rotate relatively with the first rotary member and having second torque transmission members opposing to the first torque transmission members, and a viscous fluid chamber in which the first torque transmission members and the second torque transmission members are arranged and pouring viscous fluid into the viscous fluid chamber, the first rotary member and the second rotary member are relatively rotated while viscous fluid is poured into the viscous fluid chamber, and viscosity of viscous fluid to be added to the viscous fluid chamber is set based on torque transmitted between the first rotary member and the second rotary member and filling rate of viscous fluid into the viscous fluid chamber.
