Abstract: A beam reinforcing metallic material includes a welding surface, a counter-flange-part surface, a contacting surface, a protrusion, and the like. The beam reinforcing material is a member that is made of metal such as steel for example. The beam reinforcing metallic material is not plate shaped but has a three dimensional shape. More particularly, the cross-sectional shape varies from the edge parts toward the center part in longitudinal direction. The cross section (cross-sectional area) of the center part of the beam reinforcing metallic material in longitudinal direction is larger than the cross sections (cross-sectional areas) of the both end parts. Increasing the cross-sectional area of the vicinity of the center part of the beam reinforcing metallic material allows the part that receives maximum stress to securely obtain the flexural strength when the beam reinforcing metallic material is fixed to the beam.
