A vehicle body frame member has an impact absorbing portion 14, which is shaped like a rectangular tube and has four side walls 10,11,12,13 and a tube axis L. At least one of the four side walls has a row of protrusions configured by an odd number of protrusions 15, 16, 17 aligned in the direction of the tube axis. Each of the protrusions protrudes outward in a radial direction of the impact absorbing portion and extends along the side wall in a direction perpendicular to the tube axis. The protruding amount of the even-numbered protrusions h2 is greater than the protruding amount of the odd-numbered protrusions h1,h3.
