Liquid sealed-type vibration insulating device

A liquid sealed-type vibration-insulating device comprises:

• 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 located between the upper and lower connection members for receiving vibrations from the vibrating member;
• an annular plate fixed 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 which is connected between an upper open end of the tubular metal member and the upper connection member, and covers the vibration-insulating rubber member;
• a main liquid chamber which is formed by the vibration-insulating rubber member and the lower connection member, and is located beneath the vibration-insulating rubber member;
• an auxiliary liquid chamber which is formed by the vibration-insulating rubber member and the heat-resistant rubber sheet member, and is surrounding an upper side of the vibration-insulating rubber member;
• a liquid filled in the main liquid chamber and the auxiliary liquid chamber;
• 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, wherein the stopper member abuts against the annular plate and a bottom of the lower connection member serving as a stopper mechanism operative in upward and downward directions, and also abuts against a side wall of said lower connection member serving as a stopper mechanism operative in a radial direction.
