Abstract
A dynamic damper including: a mass member; a support frame member having a substantially rectangular support frame portion surrounding the mass member with a given gap distance therebetween and a pair of support sides opposed to each other in a first direction with the mass member disposed therebetween. A plurality of elastic connecting members are disposed in spaces defined between the support sides and opposing end faces of the mass member, respectively, and elastically connect the mass member with respect to the support sides. The support frame portion is deformed so that the pair of support sides are relatively displaced toward each other, to thereby pre-compress the plurality of elastic connecting members. A method of producing such a dynamic damper is also disclosed.
