PURPOSE:To obtain a sure vibration damping action and reduce the spring constant of a supporting spring by providing a spring body and a weight member which is supported by this spring body and placing leaf spring mechanisms at least in three places around the weight member. CONSTITUTION:A dynamic vibration reducing device D includes a spring body 1, a weight member 2 which is supported by the spring body 1, and the guide member 3 of the weight member 2, and a viscous shear resistance member 4 is added thereto. A leaf spring mechanism 32 consists of thin leaf springs 34, an arm member 36 with an inner cylinder and an arm member 38 with an outer cylinder for supporting the thin leaf springs 34, ana pad plates for fixing these, and the like. The leaf spring mechanisms 32 are placed around the weight member 2 in at least three places. Thereby, sure vibration damping action can be obtained even to a minute vibration, enabling the reduction in the spring constant of the supporting springs. |
