Abstract
A dynamic dater mounted on a rod-shaped oscillating member is disclosed, which includes: a cylindrical mass member disposed radially outwardly of the oscillating member and formed of a metallic material by forging, while being subjected to a scale-removal treatment; an elastic support member for elastically supporting the metallic mass member for connection thereof with the oscillating member; and an elastic covering layer adapted to cover a substantially entire area of the surface of the metallic mass member and integrally formed with the elastic support member. The elastic covering layer is fixed in close contact with the substantially entire area of the outer surface of the mass member, so that the metallic mass member is firmly secured to the elastic support member without using an adhesive. A method of producing the dynamic damper is also disclosed.
