Problem: To reduce vibration and noise of a bracket and the like, and also to save a work for manufacturing and shorten manufacturing time, in the case that a forced-excitation of a vibrating apparatus is a cause. Solution: There are provided a frame body 1, to which a rotation motor 6 is fixed, and dynamic vibration absorbers 2, 3 which are structured in a manner such that slits are made in a portion of the frame body 1 and the slit part is bent in an upward direction, and is configured so that the vibrating portions 2a, 3a of the dynamic vibration absorbers 2, 3 vibrate in the vibrating direction of the frame body 1 being vibrated by the rotation motor 6.
