Further, the cross-section of the fixed joint-filling material 10 has a taper shape in which thickness gradually reduces from the inner hole near part 10a toward the outer circumferential edge part 10b so as to be the reduced-diameter part side. Provided that the thickness of the edge face on the inner hole near part 10a in which the thickness is made the maximum in the fixed joint-filling material is defined as A and the thickness of the edge face on the outer circumferential edge part 10b in which the thickness is made the minimum in the fixed joint-filling material 10 is defined as B, A×(1-the compression rate of the fixed joint-filling material 10)≤B is satisfied.
