<p>PROBLEM TO BE SOLVED: To obtain a torque transmission joint 15a which can suppress the generation of noise based on relative displacement between an output shaft 12a and a worm shaft 6a of an electric motor 7 irrespective of a temperature change.SOLUTION: A buffer member 18a formed of an elastic material is assembled between a drive-side transmission member 16a supported to an output shaft 12a and a driven-side transmission member 17a supported to a worm shaft 6a. Then, a part to be gripped constituting the buffer member 18a is interposed between a drive-side arm part 21a constituting the drive-side transmission member 16 and a driven-side arm part 23a constituting the driven-side transmission member 17a. A wooden axial preload member 26 excellent in heat resistance and cold resistance is arranged separately from the buffer member 18a, and pressure-inserted into a support cylinder part 44 arranged at the buffer member 18a. Then, the axial preload member 26 is arranged between the output shaft 12a and the worm shaft 6 in a state of being compressed in an axial direction, and preloads are imparted to both the shafts 6a, 12a.</p> |
