Each of the plurality of side parts is positioned on the same side as a plane containing a ring, and a center line of the side part in a direction where the side part gets away from the projected part with which the side part contacts is substantially perpendicular to a circumferential direction of a support part at a position intersecting the center line of the projected part.
