To realize a vehicle vibration absorption structure that can reduce costs and spaces while reducing vibration transmitted to a vehicle body by suppressing resonant oscillation on a mount member generated by vibration transmitted from a unit as a source of vibration.SOLUTION: A vehicle rear part structure includes: a unit 10 mounted as a source of vibration in a vehicle; a mount member 30 disposed between the unit 10 and vehicle bodies 20 and 70 to connect therebetween; and a stay 40 connecting the unit 10 and the mount member 30 to be fixed to the unit and the mount member. The stay 40 includes: a first fixation portion 42 fixed to the unit 10; a second fixation portion 44 fixed to the mount member 30; and an expansion portion 46 that is expandable. The natural frequency of the mount member 30 fixed to the stay 40 is adjusted by the setting of elasticity of the expansion portion 46.SELECTED DRAWING: Figure 2

    【課題】振動源であるユニットから伝達される振動により生じるマウント部材での共振振動を抑制して、車体に伝わる振動を低減しつつ、コストとスペースを抑えられる車両防振構造を実現する。【解決手段】車両後部構造は、車両に搭載され振動源となるユニット10と、前記ユニット10と車体20および70との間に設けられ、両者を連結するマウント部材30と、前記ユニット10と前記マウント部材30を連結し、両者に固定されるステー40と、を備え、前記ステー40は、前記ユニット10に固定される第一固定部42と、前記マウント部材30に固定される第二固定部44と、伸縮可能な伸縮部46と、を有し、前記伸縮部46の伸縮特性の設定により、前記ステー40に固定された前記マウント部材30の固有振動数を調整する。【選択図】図2
