1. A support device that supports a support object including a circumferential surface, the support device comprising:
a base portion;
a pair of support members provided slidably with respect to the base portion, and provided with cutout portions having an arc shape and configured to hold the circumferential surface from both sides;
a plurality of first elastic bodies configured to bias the pair of support members in directions in which the support members approach each other;
a plurality of bearing portions provided along the cutout portions of the pair of support members, and configured to hold the support object in a manner so that the support object is rotatable about an axis of the support object; and
a plurality of second elastic bodies configured to bias the plurality of bearing portions toward the support object in order for the plurality of bearing portions to hold the support object, wherein the support device is configured to switch between a first state and a second state,
wherein
the first state is a state where the circumferential surface and each of the cutout portions of the pair of support members come into contact with each other, whereby the pair of support members supports the support object while relative rotation of the support object relative to the base portion is suppressed, and
the second state is a state where the circumferential surface and each of the cutout portions of the pair of support members separate from each other and the circumferential surface and the plurality of bearing portions come into contact with each other, whereby the plurality of bearing portions support the support object while the relative rotation is allowed.
