a plurality of elastic plates that are disposed about an axis and surround the axis in a circumferential direction, the plurality of elastic plates facing one another in a radial direction and defining a slit radially between adjacent elastic plates among the plurality of elastic plates,
wherein the plurality of elastic plates are spaced apart from one another,
wherein each of the plurality of elastic plates comprises:
an elastic portion that spirally extends about the axis and away from the axis in the radial direction,
