ABSTRACT:
A liquid sealed-type vibration-insulating device includes an upper connection member to be mounted on a vibrating member; a lower connection member of a cup-shape to be mounted on a member on a vehicle body; a vibration-insulating rubber member provided between the upper and lower connection members; an annular plate fixedly secured to a lower portion of the vibration-insulating rubber member; a tubular metal member connecting the annular plate to an upper open end of the lower connection member; a heat-resistant rubber sheet member connected between an upper open end of the tubular metal member and the upper connection member; a main liquid chamber formed by the vibration-insulating rubber member and the lower connection member; an auxiliary liquid chamber formed by the vibration-insulating rubber member and the heat-resistant rubber sheet member; an orifice communicating the main liquid chamber with the auxiliary liquid chamber; and a stopper member which is connected to the upper connection member and is located within the main liquid chamber. The stopper member abuts against the annular plate and a bottom of the lower connection member which serves as a stopper mechanism operative in upward and downward directions. The stopper also abuts against a side wall of the lower connection member which serves as a stopper mechanism operative in a radial direction.
