Abstract
A vibration-proof mount includes an inner shell member comprised of a center pipe and a bush, and an outer shell member including a first collar and a second collar. The center pipe and the outer shell member are connected to each other by first and second elastomer members with a liquid encapsulated therein. A liquid chamber is formed between the first and second elastomer members and expanded and contracted in volume by a load, and an orifice is defined in the first elastomer member and connected to the liquid chamber. The orifice is formed by only a wall surface of the first elastomer member and hence, the sectional area of a flow path in the orifice can be insured to prevent a difference in characteristic between individuals of the vibration-proof mount, as compared with the case where the orifice is defined between a plurality of members.
