A flange portion obtained by crimping and folding the wall portions at both sides of the diameter-reduced portion in an axial direction according to a press working is formed so as to be continuously provided in an inner diameter side of one end of the tubular portion, and the flange portion is clamped between a mounting bracket and a support member.
