<P>PROBLEM TO BE SOLVED: To provide a structure of a wooden fitting which effectively prevents wooden material formed of a plurality of base materials including moisture-proof layers therebetween from being warped with less moisture-proof layers. <P>SOLUTION: A wooden fitting 100 has a frame assembly structure composed of frame members and panel members. Three frame base materials 11, 12, and 13 are laminated across moisture-proof layers 1 and 1 to form the frame member 10. The frame member 10 segmented into a plurality of block layers with each of the moisture-proof layers 1 and 1 as a boundary in thickness direction is formed such that the thickness of the inner block layer is larger than the thickness of the outer block layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
