Abstract
A long damping orifice 60 having a circular shape as viewed from above and a short linear idle orifice 61 are disposed and the orifices are connected by a common inlet 32, whereas an outlet side is formed separately into a first outlet 52 and a second outlet 53, which is opened and closed by a valve portion 21 which is in a unit with a diaphragm 7. Though the valve portion 21 is open by the negative suction-air pressure of an engine during idling, at this time, since the center of the second outlet 53 is shifted from the center of the valve body 21 toward a flowing direction of fluid flowing through the idle orifice 61, the valve portion 21 is open obliquely to prevent the turbulent flow of fluid in the vicinity of the second outlet 53, switching fluid-sealed mount characteristics rapidly.
