PURPOSE:To improve service life of a mount by separating an elastic rubber body into an outer circumferential rubber separating section formed with a pressure receiving chamber and an inner circumferential separating section coupled with an inner cylindrical member through a through-hole. CONSTITUTION:An inner cylindrical metal 10 and an outer cylindrical metal 12 are arranged while being shifted by predetermined amount in radial direction and coupled elastically each other through an approximately semi-cylindrical elastic rubber body 14 placed between them. The elastic rubber body 14 is substantially separated into two, i.e. an inner circumferential rubber separating section 50 at the side of the inner cylindrical metal 10 and an outer circumferential rubber separating section 52 at the side of a pressure receiving section 40. A through-hole 54 having approximately arched cross-section is penetrated axially through the mount such that the pressure receiving chamber 40 is placed at the inside of the arch. The width of the through-hole 54 is set such that the rubber separating sections 50, 52 contact each other with a predetermined compression margin. |
