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

    【課題】メインマフラに流入する排気の温度が上昇したときにおける液封式制振装置の振動減衰効果の低下を抑制することができる排気管制振構造を提供する。【解決手段】排気管制振構造は、メインマフラの車両幅方向両端を支持する一対のロッド部材21と、ロッド部材21を支持するとともにブラケットを介して車体に支持されている一対の液封式制振装置22とを備える。液封式制振装置22は、外筒部材31と、内側にロッド部材21の一部が配置されている内筒部材32と、内筒部材32と外筒部材31との間に配置されている弾性部材33とを備える。液封式制振装置22には、外筒部材31と弾性部材33とによって区画された、一対の液室34及びオリフィス35が設けられている。オリフィス35は、弾性部材33における内筒部材32よりも車両幅方向外側に位置する部位である特定部位33cの車両幅方向外側の端部と外筒部材31とによって区画されている。【選択図】図7
