PROBLEM TO BE SOLVED: To reduce the manufacturing cost as a whole by forming a fitting part of a window plate to have a shape including the whole body so as to make it possible to form a plurality of kinds of windows having mutually overlapping part and non-overlapping part. SOLUTION: A window opening is formed at the fitting part 9 of a window plate whose peripheral edge is shaped stepwise and formed recessively or protrusively and the window plate covering these openings is attached to the fitting part 9 to form windows 7A, 7B. In this case, the fitting part 9 of the window plate is formed to have a shape including the whole body of the overlapping part and the non-overlapping part of these windows 7A, 7B so that the windows 7A, 7B comprising at least two kinds of shapes having the mutually overlapping part and the non-overlapping part can be formed respectively. In this way, even when cabs for different kinds of machines, having mutually different shapes from each other are manufactured, the manufacture cost can be reduced as a whole. |
