Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust pipe vibration control structure capable of suppressing decline of vibration reduction effect of a liquid seal type vibration control device, when temperature of exhaust flowing into a main muffler rises.SOLUTION: An exhaust pipe vibration control structure includes: a pair of rod members 21 which supports both edges in a vehicle width direction of a main muffler; and a pair of liquid seal type vibration control devices 22 which supports the rod members 21 and is supported by a vehicle body via brackets. The liquid seal type vibration control device 22 includes: an outer cylindrical member 31; an inner cylindrical member 32 in which a part of the rod members 21 is disposed inside thereof; and an elastic member 33 disposed between the inner cylindrical member 32 and the outer cylindrical member 31. In the liquid seal type vibration control devices 22, a pair of liquid chambers 34 and a pair of orifices 35 are disposed which are defined by the outer cylindrical member 31 and the elastic member 33. The orifice 35 is defined by the outer cylindrical member 31 and the end part outside in the vehicle width direction of a specific portion 33c which is a portion located more outside in the vehicle width direction than the inner cylindrical member 32 in the elastic member 33.SELECTED DRAWING: Figure 7
