PURPOSE: To provide a liquid sealed type mount for effecting required vibration damping force and vibration isolation performance by reducing the number of part items and facilitating manufacture. CONSTITUTION: A supporting cylinder part 14 is integrally formed in a cup member 12 of a case 1 and inner periphery neighborhood of a diaphragm 4 is fixed with it closely contacted with an opening periphery 53a of an idle orifice 53 by this supporting cylinder part 14. A second liquid chamber B communicates with a first liquid chamber A through a shock orifice 52 of a small diameter and a lower end opening of the idle orifice 53 is closed by an inner periphery part 42 of the diaphragm 4. Charging liquid L flows between the first liquid chamber A and the second liquid chamber B through the shock orifice 52 at the time of a low frequency and large displacement charging and lowering of dynamic spring constant due to liquid column resonance of charging liquid L at the idle orifice 53 is made possible by the inner periphery 42 of the diaphragm at idle oscillation input. |
