PROBLEM TO BE SOLVED: To secure a crush zone by breaking a mount bracket supporting a front face of a power unit and efficiently absorb impact energy by axial crush or deformation of a vehicle body frame at the time of head-on collision. SOLUTION: This power unit support structure is provided with the mount bracket 21 fixed to the power unit 14, a mount member 24 fixed to a sub-frame 7 supported by front side frames 4L, 4R, a first arm part 22 extended from the mount bracket 21 and a second arm member 23 having a tip part to which the mount member 24 is fixed. The second arm member 23 is jointed to the mount member 24 via a first jointing part 29, and the first arm part 22 is jointed to a rear end part of the second arm member 23 via a second jointing part 26. At the time of frontal collision, first, the first jointing part 29 is broken, and then, the second jointing part 26 is broken. COPYRIGHT: (C)2008,JPO&INPIT
