PROBLEM TO BE SOLVED: To prevent a vibration in a roll direction at a power train installed on a vehicle from being transmitted to a vehicle body.SOLUTION: This invention comprises: a pair of opposing plates 33, 33 fixed to one side frame 25 in such a way that they are oppositely faced to each other at both sides in a roll direction of a protrusion piece 27 of a power train 23; and a stopper rubber 35 arranged at a location opposing the protrusion piece 27 of each of the opposing plates 33. The stopper rubber 35 has a first protrusion part 35a pre-compressed in a roll direction by the opposing plates 33 and the protrusion piece 27, and second protrusions 35b, 35b abutted against the protrusion piece 27 when the power train 23 vibrates in a roll direction.

    【課題】車両に搭載されたパワートレインにおけるロール方向の振動の車体への伝達を防止する。【解決手段】パワートレイン23の突出片27のロール方向両側に互いに対向するように一方のサイドフレーム25に固定される一対の対向板部33,33と、各対向板部33の突出片27と対向する部位に設けられたストッパラバー35と、を備え、ストッパラバー35は、対向板部33と突出片27とによってロール方向に予圧縮される第1突条部35aと、突出片27から間隔をあけて設けられ、パワートレイン23がロール方向に振動する際に突出片27と当接する第2突条部35b,35bと、を有する。【選択図】図2
