PROBLEM TO BE SOLVED: To satisfy both improvement of coupling rigidity of a vehicle attachment unit in a subframe with a vehicle body and acceleration of detachment of the subframe in collision.SOLUTION: High friction means 70 with a higher coefficient of friction than that between a subframe 1 and a coupling member 65 is provided to an abutting surface 41 between a vehicle body attachment unit 6 and a subframe supporting unit in a front subframe structure including: the coupling member 65 coupling the vehicle body attachment unit 6 in a rear portion of the subframe 1 and the subframe supporting unit on the vehicle body side; an opening having the coupling member 65 inserted through the vehicle body attachment unit 6 and the subframe supporting unit as well as allowing a tolerance with the coupling member 65; and detachment means 62 for having the subframe 1 detached from the vehicle body by using backing weight of the subframe 1 between the vehicle body attachment unit 6 and the subframe supporting unit.SELECTED DRAWING: Figure 4

    【課題】サブフレームにおける車体取付部の車体との連結剛性向上と衝突時のサブフレームの離脱促進とを両立すること。【解決手段】サブフレーム1後部における車体取付部6と車体側におけるサブフレーム支持部とを連結する連結部材65が設けられ、車体取付部6とサブフレーム支持部とに連結部材65を挿通するとともに連結部材65との間に公差を許容する開口が設けられ、車体取付部6とサブフレーム支持部との間にサブフレーム1の後退荷重を利用して当該サブフレーム1を車体から離脱させる離脱手段62が設けられたものにおいて、車体取付部6とサブフレーム支持部との間の当接面41に対し、サブフレーム1と連結部材65との間の摩擦係数よりも高い高摩擦手段70を設けた。【選択図】図4
