Document Type and Number:
Japanese Patent JP7140709
Kind Code:
B2
Abstract:
To provide a dynamic vibration absorber that can suppress temperature dependency of vibration absorption property.SOLUTION: A dynamic vibration absorber includes: a leaf spring of which one end is fixed; a mass body fixed to the leaf spring; and a viscoelastic body connected to one of the principal surfaces of the leaf spring and an opposite object opposite to the principal surface, and having a stiffness that decreases as the temperature increases. The leaf spring deforms in a direction of the viscoelastic body as the temperature increases.SELECTED DRAWING: Figure 1
