For example, the elastic member 130 may include a vibration-proof rubber made of a synthetic rubber material. In this embodiment, the elastic member 130 is described as an example of a vibration-proof rubber, but is not limited thereto. For example, the elastic member 130 may be variously applied as long as it is a material capable of absorbing vibration transmitted from the outside and preventing sagging.

The plurality of reinforcing plates 134 may be stacked in the elastic body 131 . For example, by disposing the elastic body 131 between the plurality of reinforcing plates 134 , the hardness of the elastic body 131 may be increased.
