<P>PROBLEM TO BE SOLVED: To provide a door body configured by using a pair of first and second surface plates at the front and back comprising a metallic plate material with excellent dimension accuracy. <P>SOLUTION: When configuring a door body 6 by bending a pair of first and second surface plates 7 and 8 at the front and back comprising the metallic plate material, a first depth piece part 7c on a door end side formed on a first surface plate 7 at least is formed so as to reach a second width piece part 8a from the distal end edge of a first folded piece part 7b folded to a door tail side from the distal end edge of a first width piece part 7a. The first folded piece part 7b is folded such that a distal end side part is abutted to the first width piece part 7a, and also the first depth piece part 7c is formed by being bent orthogonally to the first width piece part from the distal end edge of the first folded piece part 7b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
