A vehicle body frame member has an impact absorbing portion, which is shaped like a rectangular tube and has four side walls and a tube axis. At least one of the four side walls has a row of protrusions configured by an odd number of protrusions 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 is greater than the protruding amount of the odd-numbered protrusions.
