Claims

[Claims for Utility Model Registration] An engine mount that supports a power unit equipped with an automatic transmission on a vehicle body, comprising an elastic body disposed between the vehicle body and the power unit, and an input power unit disposed in parallel with the elastic body. It is equipped with a main fluid chamber whose volume is changed by vibration, and a sub-fluid chamber whose volume is variable and which is communicated with the main fluid chamber via an electrode orifice. In a control type engine mount in which an electrorheological fluid whose viscosity is changed is sealed and the flow state of the fluid in the electrode orifice is changed according to a change in the voltage applied to the electrode orifice, the select position of the automatic transmission described above is switched. The present invention is characterized in that it is provided with a select detection means for detecting, and a control means for receiving a select switching signal detected by the select detection means and outputting a control voltage for increasing the viscosity of the electrorheological fluid to the electrode orifice for a predetermined period of time. Controlled engine mount.
