バネ定数は高くなる傾向がある。The mounting part paulownia connected to the vibration source and the base Bl on which the vibration source is mounted are connected by an umbrella-like elastic member to form a fluid chamber inside, and the fluid chamber is further connected to the diaphragm chamber through all orifices of the fluid chamber. Fluid-filled mounts are known in which fluid-filled mounts are known which dampen vibrations during low frequency strokes, but tend to have high dynamic spring constants during high frequency small strokes.

段の弾性部材により動的バネ定数が低下し、微振動を上
部の円柱状の弾性部材で吸収できるため、高周波小スト
ローク時の振動遮断性能の向上が図扛る。Therefore, a cylindrical elastic member is stacked on top of the middle part of the umbrella-shaped elastic part with a metal intermediate part interposed therebetween, and a fluid-filled mount is constructed in which the mounting member is coupled to the upper surface of the cylindrical elastic part. It has already been proposed and put into practical use. That is, series 2
The dynamic spring constant is lowered by the elastic member in the step, and minute vibrations can be absorbed by the upper cylindrical elastic member, resulting in a significant improvement in vibration isolation performance during high frequency and small strokes.

が劣るという不利がある。However, when obtaining such two-stage elastic members in series by vulcanization molding, processing efficiency is poor if each is molded separately.
In addition, if the rubber injection end mark that is separated after molding remains on the peripheral wall of each elastic member that expands and contracts, stress will concentrate on the rubber material injection end mark due to repeated expansion and contraction, resulting in cracks and poor durability. There is.

供するにある。The present invention has been made in view of the above-mentioned disadvantages and to solve them all at once.The purpose of the present invention is to mold two stages of elastic members in series with one set of molds to improve processing efficiency. Another object of the present invention is to provide a fluid-filled mount designed to improve durability by making the rubber phase injection part ingenious so that no trace of the rubber phase injection end remains on the peripheral walls of both elastic members when separated after molding.
