Patent abstract
A one-way damper includes a cylindrical housing, a viscous fluid contained within the housing, a rotor rotatably disposed in the housing, and a valve body. The rotor has a center part for forming a rotational center, and a control wall extending radially outwardly from the center part for dividing an inside of the housing. The control wall has a distribution path. The valve body has a holding part for holding the center part, and a free edge part extending from one side of the holding part for opening-and closing the distribution path. A seal member prevents the viscous fluid from leaking between the housing and the rotor.
