Title:
ACTIVE DAMPER
Document Type and Number:
Japanese Patent JP3733745
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve and stabilize generation efficiency of exciting force and to improve durability by preventing sliding contact between components during operation in an active damper which exerts canceling damping effect by exerting an exciting force to an object to be damped.
SOLUTION: A fixed member 12 fixed to a vibration member 34, and a mass member 14 supported by elastic supporting means 16 so as to be displaceable with respect to the vibration member 34 are opposed apart from each other, and a magnetic attraction force or magnetic repulsion force by electromagnet means 18 is exerted on the fixed member 12 and the mass member 14, thereby relatively displacing the mass member 14 with respect to the fixed member 12 in a direction of approaching/leaving the fixed member 12.
