To reduce a load applied to a member in the mount structure of the drive unit of a vehicle and to secure as much as possible a working space for fitting members.SOLUTION: A mount body 24 fixed to a vehicle-body skeleton supports a drive unit 30 via a bracket 26 and a spacer 28. The bracket is fastened to the mount body 24 along a body fastening shaft 42 extending in forward and backward directions. The bracket includes: a front-side fastening portion 60 extending in a forward direction of a vehicle and fastened to the spacer; and a back-side fastening portion 62 extending in a backward direction of the vehicle and fastened to the spacer. The front-side fastening portion 60 and the back-side fastening portion 62 are located in a vertical direction and between the body fastening shaft 42 and a fastening portion 86 of the spacer relative to the drive unit. The front-side fastening portion 60, which is subjected to compression force between itself and the spacer due to a moment MU generated in the drive unit by torque T of a drive wheel 90, has a shorter distance from the body fastening shaft 42 in the vertical direction than the back-side fastening portion 62 (α<β).SELECTED DRAWING: Figure 3

    【課題】車両の駆動ユニットのマウント構造における部材に掛かる負荷を低減し、部材組み付け時の作業スペースをできる限り確保する。【解決手段】車体骨格に固定されたマウント本体24は、ブラケット26とスペーサ28を介して駆動ユニット30を支持する。ブラケットは前後方向に延びる本体締結軸42に沿ってマウント本体24と締結されている。ブラケットは、車両前方に張り出してスペーサと締結される前側締結部60と、車両後方に張り出してスペーサと締結される後側締結部62を含む。前側締結部60と後側締結部62は、上下方向において、本体締結軸42と、スペーサの駆動ユニットとの締結部86との間に位置する。駆動輪90のトルクTにより駆動ユニットに生じるモーメントMUにより、スペーサとの間で圧縮する力が掛かる前側締結部60は、後側締結部62に比べて、上下方向の本体締結軸42との距離が短くなっている(α<β)。【選択図】図3
