• wherein:
• the first and second peripheral wall portions are separably displaceable against a biasing force of the biasing means,
• both the first and second peripheral wall portions have the inner surface having the arcuate cross-section,
• the arcuate protrusion is provided on the inner surface of one of the first and second peripheral wall portions, and
• linear connecting portions projecting radially inward while extending in an axial direction of the inner surface are provided at a plurality of positions separated in the circumferential direction on the inner surface of the other of the first and second peripheral wall portions.
