PURPOSE: To reduce noise by virtue of an optimum damper frequency as a result of tuning frequency of a right and a left dynamic dampers separately, as well as to protect an engine mount from thermic damage by providing right and left dampers in different positions of right and left engine mounts, respectively

CONSTITUTION: A right side and a left side engine mountings 28, 46 are provided between a right side and a left side engine brackets 16, 18 and a right side and a left side brake brackets 22, 26. Aright side and a left side dynamic dampers 62, 64 are provided on the right side and the left side engine mountings 28, 46. A right side damper elastic body adheres to, for example, the upper portion 30U of a right side mounting body 30 and a left side damper elastic body adheres to, for example, the bottom portion 48U of a left side mounting body 48. The right side and the left side dynamic dampers 62, 64 are set to different frequencies and tuned to optimum frequencies by means of changing the configurations and the weights of a right side and a left side damper mass bodies.
