PROBLEM TO BE SOLVED: To provide a temporarily fastening structure for an engine mount, by which an engine unit can be temporarily fastened to a vehicle body accurately.SOLUTION: A bolt 62 for temporarily fastening, which is projected downward from an engine mount bracket 16 during the assembly of a vehicle, is inserted into an insertion hole 78 in a seat 71 of a transmission 20, and tightened (temporarily fastened) with a nut 80. In this case, the axial length L2 of the insertion part 66 of the bolt 62 for temporarily fastening is longer than the axial length L1 of the insertion hole 78 and, in the insertion part 66, a tapering part 70 made larger in diameter than a screw part 68 is formed adjacent to the screw part 68. Therefore, the nut 80 tightened on the screw part 68 is prevented from being moved upward as far as the position of the insertion part 66. As a result, the reaction of tightening torque is prevented from acting between the engine mount bracket 16 and the transmission 20, resulting in relative displacement of both. Accordingly, an engine unit can be temporarily fastened to the vehicle accurately.SELECTED DRAWING: Figure 3

    【課題】車体に対してエンジンユニットを精度良く仮止めできるエンジンマウントの仮止め構造を提供する。【解決手段】車両の組立時にエンジンマウントブラケット16から下方に突出配置された仮止め用ボルト62がトランスミッション20の台座71の挿通孔78に挿入され、ナット80で締結(仮止め)される。この際、仮止め用ボルト62の挿通部66の軸方向長さL2は、挿通孔78の軸方向長さL1よりも長く、挿通部66にはネジ部68に隣接してネジ部68よりも拡径したテーパ部70が形成されている。したがって、ネジ部68に締結されたナット80が挿通部66の位置まで上昇することはない。この結果、締結トルクの反力がエンジンマウントブラケット16とトランスミッション20間に作用して両者が相対的に変位することが防止される。したがって、車両に対してエンジンユニットを精度良く仮止めすることができる。【選択図】図3
