A channel member for constructing an elongated wall portion of a vehicle body, having, as viewed in the cross section, first and second side wall portions (12B) extending substantially perpendicularly to a direction of transverse extension of the elongated wall portion so as to define opposite sides of the channel member, first and second bottom wall portions (12F) extending substantially in parallel with the direction of transverse extension of the elongated wall portion and connected with the first and second side wall portions (12B) along adjacent ends thereof, first and second perpendicular intermediate wall portions (12G) extending substantially transversely to the direction of transverse extension of the elongated wall portion and connected with the first and second bottom wall portions (12F) along adjacent ends thereof, and a central wall portion (12E) extending between the first and second perpendicular intermediate wall portions (12G) and connected with the first and second perpendicular intermediate wall portions (12G) along adjacent ends thereof.
