Abstract
A dynamic damper includes a metallic weight having a predetermined resonance frequency, a support member to be connected to an oscillating member in a vehicle to which the damper is applied, a rubber resilient member bonded by vulcanization to the metallic weight and the support member, a cover member attached to the support member in fluid-tight sealing relation thereto and encircling the support member, the resilient member and a part of the metallic weight, and a membrane secured on the metallic weight, a peripheral end portion of which is in fluid-tight contact with an inner peripheral wall surface of the cover member and is slidable therealong.
Claims6
A dynamic damper comprising:
- a weight having a predetermined resonance frequency;
- a support member a part of which is to be connected to an oscillating member;
- a resilient member made of a resilient material, said resilient member disposed between said weight and said support member and fixed thereto;
- a hollow cover member for encircling said support member, said resilient member and at least a part of said weight, and for providing at one end portion thereof a seal between said support member and said cover member;
- and
- a membrane made of the same material as said resilient member, said membrane fixed at a part thereof on said weight and having an outer periphery being in fluid-tightly contact with an inner wall surface of said cover member while permitting a slidable movement of said membrane along said cover member.
