Patent ID: 7111705

Claim:
A vibration isolating mount device for elastically supporting one of left and right end portions of a power plant mounted on a vehicle with a length direction of the power plant aligned in a traverse direction of a body of the vehicle, the vibration isolating mount device having an oscillation limiting mechanism for limiting oscillation of the power plant in a roll direction thereof, wherein the oscillation limiting mechanism has a receiving member for a force in a vehicle body longitudinal direction receiving at least a compressive force in the vehicle body longitudinal direction between a member of the vehicle body and a member of the power plant facing each other in the vehicle body longitudinal direction, the receiving member is constructed of: a rubber portion and a core body made of a material higher in stiffness than the rubber portion and provided integrally with the rubber portion in a single piece at least so as to be revolvable around an axis in the vehicle body traverse direction by a predetermined angle or more, a hollow portion is formed in the rubber portion of the receiving member at least so that the core body can be revolved around an axis in the vehicle body traverse direction, the hollow portion is formed so as to communicate with outside the rubber portion and at least one of inner walls in front and rear portions of the rubber portion enclosing the hollow portion has a swell portion swelling relatively into the hollow portion on one of upper and lower sides thereof, the core body being embedded at least in the swell portion.
