Vibration body unit and vibration body support structure

A vibration body unit, comprising:

• a vibration body;
• an inner cylinder that surrounds a circumference of the vibration body and that is elastically deformable;
• an outer cylinder that surrounds a circumference of the inner cylinder and that has an attachment section which is attached to a base part;
• a plurality of first spacers that are interposed between the vibration body and the inner cylinder and that are arranged to be spaced in a circumferential direction;
• and
• a plurality of second spacers that are interposed between the inner cylinder and the outer cylinder and that are arranged to be spaced in a circumferential direction,
• wherein the plurality of first spacers and the plurality of second spacers are arranged such that at least part of each of the plurality of first spacers faces each of the plurality of second spacers in a radial direction across the inner cylinder,
• the plurality of first spacers are formed integrally with the vibration body,
• the vibration body is supported by the inner cylinder via the plurality of first spacers, and
• the inner cylinder is supported by the outer cylinder via the plurality of second spacers.
