Abstract
A metal plate comprises two flat wall forming portionsconnected together by a joint portion, a plurality of reinforcing wall forming portionsupwardly projecting from each of the wall forming portionsintegrally therewith, and a side wall forming portionformed at each of opposite side edges of the plate and upwardly projecting therefrom integrally therewith. A projectionis formed on the upper end of the reinforcing wall forming portionon the flat wall portion, and a recessfor the projectionto fit in is formed in the upper end of the wall forming portionto be butted against the portionand provided on the other flat wall portion. The metal plate satisfies the relationships of: A>a, A/a≦1.5, B/b≦1.5, C/c≦1.5, and D/d/≦1.5 wherein A is the cross sectional area of the projection, B is the height of the projection, C is the maximum width of the projection, D is the width of upper end of the projection, a is the cross sectional area of the recess, b is the depth of the recess, c is the maximum width of the recess, and d is the width of an opening of the recess
