ABSTRACT:
A dynamic damper for damping vibration of a rotary shaft. The dynamic damper includes a tubular mass member and a rubber elastic member. The rubber elastic member includes an attachment tube press-fitted onto the rotary shaft and an arm. The attachment tube is disposed coaxially with the mass member but nearer to an axial center thereof than the mass member. The arm connects the attachment tube to the mass member. The attachment tube includes a tubular support portion connected to the arm, a tubular attachment portion, and a tubular coupling portion for coupling the tubular support portion with the tubular attachment portion. The tubular attachment portion has larger interference than the tubular support portion.
