ABSTRACT:
Disposed is a supporting mount for a power plant such as an engine or a transmission. The power plant includes an inner pipe and an outer pipe, a vibration absorbing member interposed between the inner pipe and the outer pipe, a rolling restriction member connected to the inner pipe and which restricts the power plant from vibrating more than a predetermined amount with relation to a vehicle frame, first and second fluid chambers formed in the vibration absorbing member and which are filled with operating fluid, first and second fluid communicating passages communicating the first and second fluid chambers, a displacement reaction portion provided in the outer pipe and which reacts to substantial movement by the outer pipe by contact with the rolling restriction member, and a fluid passage adjusting portion which decreases a size of the second fluid communicating passage in direct proportion to the amount of rolling of the engine or transmission to which the displacement reaction portion responds.
