PURPOSE:To effectively suppress the vibration, in the titled radiator which is attached to the vehicular body side through an elastic body so as to utilize the radiator for a dynamic damper, by altering the elastic coefficient of the elastic body according to an engine load. CONSTITUTION:A radiator 1 is supported with a radiator core support 7 and first cross member 13, located on the upper and lower sides of a vehicular body respectively, through mount rubbers 5, 11. On the upper surface of the member 13, a recessed portion 15 is formed between a pair of the mount rubbers 11 and a cam 19 rotated by a step motor 17 is arranged therein. And one end of a leaf spring 21 is fixed on the edge of the recessed portion 15 and a movable rubber 23 is attached on the upper surface of the other end thereof. Then, in the case that an air conditioner or the like is driven so that the engine load is increased, the cam 19 is rotated by the motor 17 and the movable rubber 23 is abutted to the lower surface of the radiator 1 through the leaf spring 21 so as to enhance the characteristic frequency of the radiator vibration system, thereby the vibration of the vehicular body can be suppressed.
