PROBLEM TO BE SOLVED: To provide a vibration-proof structure of a torque rod which can change a natural frequency of the torque rod while avoiding the enlargement of an arrangement space, and can prevent or suppress the propagation of vibration at an engine unit side to a valve body constituent member side.SOLUTION: A vibration-proof structure prevents or suppresses the propagation of vibration to a vehicle body constituent member side from an engine unit side by fixing a weight member 10 to a torque rod 5 which is formed by connecting a first bush 7 and a second bush 8 to each other by a connecting member 9. The second bush 8 is formed by arranging and fixing an elastic member 8c between an inner ring 8a and a metal-made outer ring 8b which is larger than the connecting member 9 in diameter, and a corner part a is formed at a connecting part between the connecting member 9 and the outer ring 8b of the second bush 8. The weight member 10 is arranged so as to embed the corner part a therein, and fixed to the connecting member 9 and the outer ring 8b.SELECTED DRAWING: Figure 5 |
