摘要

Between the first fixed part 21 and the second fixed part 22 that has an opening 24 at a position facing the first fixed part 21 apart from the first fixed part 21 and is not relatively displaceable with respect to the first fixed part 21. It is the fixing member 12 provided with the fastening part 40 arranged and fixed in the space 23. The fastening portion 40 has a shape that can rotate around a rotation axis L extending in a direction penetrating the opening 24 with respect to the first and fixed portions, and a first contact that contacts the first fixed portion 21. And a plurality of second abutting portions 52 that abut on a plurality of positions around the end of the opening 24. Each of the plurality of second contact parts 52 is inclined in the circumferential direction so as to be closer to the opening 24 toward one rotation direction, and is inclined in the radial direction so as to be closer to the opening 24 toward the rotation axis L. The guide inclined surface 42 has a rotation axis L as a center. The fastening portion 40 is fixed by rotating each guide inclined surface 42 to the second fixed portion 22 by rotation.
