The spacer 16 is made of an elastically deformable elastic material, and it is provided with an insertion hole 18 to be inserted with the steel rod 3 and a notch section 25 notched in the radial direction of the insertion hole 18 over the length direction of the insertion hole 18 and having the opening width on the inner face 21 of the insertion hole 18 smaller than the diameter of the steel rod 3. When the notch section 25 is pressed from the side of the steel rod 3, the notch section 25 is elastically deformed, and the spacer 16 is fitted to the steel rod 3.
