  • Vibration attenuating spring and damper mechanism using the same spring
    Patent number: 6062548
    Abstract: A damper mechanism for attenuating vibrations having a vibration attenuating spring element (1) which includes: a leaf spring (2) having a bent portion (4) and a pair of lever portions (5) extending from both ends of the bent portion (4); and an elastic member (3) disposed between the lever portions (5). When the leaf spring (2) is subjected to compressive forces, the lever portions (5) and the elastic member (3) are elastically deformed. Internal friction is generated in the elastic member (5). The functions typically provided by a conventional elastic member and a conventional resistance generating mechanism are realized by utilizing a simple spring element composed of the leaf spring (2) and the elastic member (3).
