Provided is a torque-transmission joint 15a that is able to reduce the thrust force that is transmitted between the output shaft 12a of an electric motor 8 and a worm shaft 6a without generating noise. A shock-absorbing member 18a that is made using an elastic material is assembled between a driving-side transmission member 16a that is supported by the output shaft 12a and a driven-side member 17a that is supported by the worm shaft 6a. Held sections 33a, 33b of the shock-absorbing member 18a are located between the side surfaces in the circumferential direction of driving-side arm sections 21a of the driving-side transmission member 16a and side surfaces in the circumferential direction of driven-side arm sections 23a of the driven-side transmission member 17a. A damper section 26 is integrally provided with the shock-absorbing member 18a, and that damper section 26 is elastically held between the tip-end surface of the output shaft 12a and the base-end surface of the worm shaft 16a.
