OIL DAMPER, AND DAMPER SYSTEM

摘要

PROBLEM TO BE SOLVED: To efficiently add damping force to two relatively displacing members.SOLUTION: An oil damper is provided between two relatively displacing members to damp vibration of the two members and has: a first connection part connected to one of the two members; a second connection part connected to the other of the two members; a first oil housing part whose capacity decreases as distance from the first connection part to the second connection part becomes longer; a second oil housing part which communicates with the first oil housing part and whose capacity increases as the distance from the first connection part to the second connection part becomes longer; and oil movable between the first oil housing part and the second oil housing part when the two members relatively displace, and damping force to be generated with displacement lager than predetermined displacement is larger than damping force to be generated with displacement equal to or less than the predetermined displacement when the two members relatively displace in a direction that the first connection part and the second connection part separate from each other.
