Dynamic damper

A dynamic damper configured to be mounted onto a tubular member mount, the tubular member mount including an inner shaft member and an outer tube member connected by an elastic body, the dynamic damper comprising:

• an attachment fitting including a tubular circumferential wall, the attachment fitting being arranged on one axial end side of the inner shaft member of the tubular member mount and fixed to the inner shaft member with the tubular circumferential wall extending in a center axis direction;
• an annular mass body spaced radially outward from the tubular circumferential wall of the attachment fitting;
• and
• a connecting rubber elastic body connecting opposed surfaces of the tubular circumferential wall and the annular mass body in an axis-perpendicular direction, wherein
• a covering rubber is integrally formed with a radially outer portion of the connecting rubber elastic body, the covering rubber spreading over axially opposite end surfaces of the annular mass body and holding to cover a radially inner portion of the annular mass body from axially opposite sides, and
• an axial dimension of the connecting rubber elastic body is smaller than that of the tubular circumferential wall.
