ELASTIC SUPPORT DEVICE

An elastic support device according to one embodiment of the present invention comprises: a first member that includes a first magnet; and a second member that includes a second magnet, that is disposed to face the first member, and that can move relatively with respect to the first member when receiving an external force. The elastic support member is configured so that the magnetic force acting between the first magnet and the second magnet acts to hold the second member at an in-situ position when the second member does not receive an external force, and to return the second member to the in-situ position when the second member does move by receiving an external force.
