Title:
DYNAMIC DAMPER
Document Type and Number:
Japanese Patent JP2016125585
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamic damper which is excellent in vibration attenuation performance in a wide frequency range.SOLUTION: A dynamic damper comprises transmission mechanisms 5, 7 and 9 which transmit relative displacement between a first member 1 and a second member 2 to an inertial mass body 4, and operate the inertial mass body 4. The transmission mechanisms 5, 7 and 9 are constituted so that an absolute value of a motion amount of the inertial mass body 4, or a change amount of the motion amount with respect to an increase amount in the case that a displacement amount is increased from a state that a relative displacement amount between the first member 1 and the second member 2 is larger than a preset prescribed amount becomes larger than an absolute value of a motion amount of the inertial mass body 4, or a change amount of the motion amount with respect to an increase amount in the case that a displacement amount is increased from a state that the relative displacement amount between the first member 1 and the second member 2 reaches the preset prescribed amount.SELECTED DRAWING: Figure 1
