PURPOSE:To lower manufacturing cost, and concurrently making an engine more compact. CONSTITUTION:The flange 74c of a casing 74 is installed on the outer circumference of a bracket 15. The inside of the casing 74 is partitioned into a first and a second air chamber 78 and 76 by a holding plate 56 and an elastic film 62, and the hold plate 56 is connected to a valve body 54 which blocks the opening section of an idle orifice 48 via a valve stem 52. At the time of shake vibration, the hold plate 56 is moved by making the second air chamber 76 negative in pressure, and the idle orifice 48 is surely closed, so that shake vibration is thereby absorbed by the action of fluid flowing into a shaking orifice 34. At the time of idle vibration, let the inside of the second air chamber 76 communicate with atmosphere, and fluid goes in and out through the idle orifice 48, so that idle vibration is thereby absorbed. |
