<P>PROBLEM TO BE SOLVED: To provide a front sub-frame mounting structure of an automobile, which is constituted so that absorptivity of impact energy in a vehicle front part is improved in a front collision of a vehicle, by actively utilizing high rigidity in the vehicle back-and-forth direction of a car body frame, in a front sub-frame to be arranged under the car body frame. <P>SOLUTION: Each of a pair of right-and-left floor frames 3 and a pair of right-and-left branched frames 44 has a portion constituting the closed cross sections, which are parted from each other in the vehicle width direction and extended in the back-and-forth direction. A left-side stopper part 42a, which is formed as a projection part between the left-side floor frame 3 and the left-side branched frame 44, is bonded directly to the portion and a right-side stopper part 42a, which is formed as another projection part between the right-side floor frame 3 and the right-side branched frame 44, is bonded directly to the portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
