PURPOSE: An engine mount for vibration test of vehicle is provided to execute vibration test with a single test sample. CONSTITUTION: An engine mount comprises an insulator(51) made of rubber, an upper steel plate(53) and a lower steel plate(55) installed on and under the insulator, respectively. A plurality of holes(57) are formed on the insulator to control spring constant of the insulator. The holes decreases the spring constant of the insulator. Steel rods are selectively inserted into the holes to increase the spring constant of the insulator. Replacement of a test sample is unnecessary for continuous test to reduce time and cost needed for a test.
