PROBLEM TO BE SOLVED: To efficiently absorb collision energy and suppress dash retreat. SOLUTION: A cross section of a dash cross member 8 is formed by a first partition chamber 8a in the front and a second partition chamber 8b in the rear. The first partition chamber 8a is formed using a triangle formed by three points including a connection point a with a rear part of a front horizontal part 50 on an upper face 5a of a side member rear part member 5, a connection point c provided at a connection point with a dash panel 3 behind it, and a point b arranged above a lower face height 5d of the front horizontal part 50 in the side member rear part member 5 and below a central height 5e of the front horizontal part 50 as a cross sectional shape.
