Vibration Isolation Structure

A vibration isolation structure, comprising:

• a rotator rotatable about an axis and including a large-diameter portion;
• a holder holding the rotator in a rotatable manner, the holder including
• an outer surface facing in an axial direction, and
• a recess recessed from the outer surface and having a larger diameter than the large-diameter portion, the recess including an inner wall facing radially inward and a bottom facing in the axial direction;
• and
• a vibration isolator between the large-diameter portion and the recess, the vibration isolator including
• a transferer being annular, the transferer including
• an inner circumferential portion in contact with the large-diameter portion,
• an outer circumferential portion fitted to the inner wall,
• a first end face facing the bottom, and
• a second end face facing in a direction opposite to a direction in which the first end face faces,
• a vibration isolation unit overlapping the first end face in the axial direction between the first end face and the bottom, the vibration isolation unit including
• a base being a plate facing in the axial direction, and
• an elastomer portion being a film covering a plate surface of the base, and
• a fixture fixing the transferer and the vibration isolation unit to the holder.
