Claim 16:
17. The joint unit according to claim 1, wherein
the input-side portion is a small-diameter annular portion coupled with the deceleration output shaft in a center thereof; and the output-side portion is a large-diameter annular portion
having the same center as the small-diameter annular portion, and coupled with the small-diameter annular portion via the strain generating portion extending from the small-diameter annular portion in a radial direction,
the large-diameter annular portion and the small-diameter annular portion have large-diameter annular portion side holes and small-diameter annular portion side holes, respectively, so that the large-diameter annular portion side hole and the small-diameter annular portion side hole are linearly arranged in the radial direction,
a fixing tool is fixed to the small-diameter annular portion side hole and a head of the fixing tool is enclosed by the large-diameter annular portion side hole having an inner diameter slightly larger than an outer diameter of the fixing tool, whereby, when strain is generated in the strain generating portion due to rotation of the output rotating body, the head of the fixing tool is in contact with an inner wall of the large-diameter annular portion side hole to restrict the strain.
