PURPOSE: Reinforcing structure of a dash lower member for a vehicle is provided to prevent temporary deformation by lowering deceleration and acceleration peak points with guiding multistage impact absorption in applying impact to the dash lower member. CONSTITUTION: A dash lower member(1) is installed between an engine room and a vehicle room, and mounted in a front side member assembly. A deceleration and acceleration peak point lowering unit(3) is installed in the dash lower member to lower the peak point of deceleration and acceleration by reinforcing the dash lower member, and composed of side panels(6) parallel to the dash panel, a front panel connected to side panels, and an upper panel connected to the side panels. The peak point of acceleration and deceleration is decreased, and deformation of the vehicle body is restricted.
