To provide a light weight resin torque rod achieved in low cost in total by shortening a time required per cycle of forming a resin torque rod body and dispensing with gluing treatment on a rubber elastic body in a large bush and a small bush.

In the resin torque rod 10, a vulcanized rubber part 26 of the small bush 12 is assembled in an outer tube 24 for the small bush of a resin torque rod body 30 by press fitting and a vulcanized rubber part 38 of the large bush 14 having a bore 48 passing through an axial direction is assembled in an outer tube 18 for the large bush by press fitting. A metal cover body 74 is fixed at an opening in an axial direction of the outer tube 18 for the large bush and the vulcanized rubber part 38 of the large bush 12 is prevented by the cover body 74 from coming off from the outer tube 18.
