PROBLEM TO BE SOLVED: To provide a liquid sealed type vibration-proof device capable of increasing a degree of freedom in design in a short-circuited path while restricting a product cost.SOLUTION: An end surface in a peripheral direction of an orifice forming member 50 is provided with a recessed groove 62. Thus, end surfaces of a pair of orifice forming members 50 in their peripheral directions are abutted to each other under attitude in which they are reversed upside-down, the short-circuited paths for communicating orifices can be formed by recessed groove 62. As a result, a structure of molding die does not become complex as found in the prior art product and the recessed groove 62 can be molded by mold. Post-processing with a drill or pressing of another member becomes unnecessary. With this arrangement, it is possible to reduce product cost. In addition, it is optionally possible to set a shape of the recessed groove 62. Accordingly, it is possible to increase a degree of freedom in design of the short-circuited paths.SELECTED DRAWING: Figure 4 |
