振マウン ・ト。A mass damper is integrally interposed in the middle part of the cylinder body, and a vibration-proofing rubber in the shape of a capped cylinder is arranged between the upper and lower fittings, with the top surface serving as the upper fitting and the bottom peripheral surface serving as the lower fitting. By airtightly joining the vibration isolating rubber and the lower metal fitting, an air chamber surrounded by the vibration isolating rubber and the lower metal fitting can be formed, and the volume can be changed, while the vibration isolating rubber is integrally connected to the upper metal fitting by a shaft passing through the vibration isolating rubber vertically and airtight. By disposing a rubber piston-like body in the air chamber to partition the air chamber into two upper and lower chambers, and by providing an orifice that communicates between the upper and lower chambers and the atmosphere, the air can be pumped in an amount corresponding to the volume change. An engine characterized in that the effective volume change can be reduced by a certain amount by allowing air to flow in and out elastically and further by providing a decompression diaphragm in relation to at least one of the upper and lower chambers. Anti-vibration mount with air damping.
