PROBLEM TO BE SOLVED: To provide a cab floor capable of lowering the vehicle height of a work machine by lowering the height position of the ceiling of a cab without remarkably restricting the height of a device or the like arranged underneath the floor of the cab, especially underneath the center portion of the floor. SOLUTION: The floor 15 of the cab 10 is so configured that the center portion 15a and both side portions 15b, 15c are unevenly formed so that the center portion 15a is arranged higher than the side portions 15b, 15c on both sides of the center portion 15a. By the center portion 15a, a setting space having higher height is formed for the device or the like arranged underneath the center portion 15a. By lowering the positions of the side portions 15b, 15c, the height of the ceiling portion 11 of the cab 10 is lowered. The stepped center portion 15a also functions as a rib improving the strength of the floor 15. COPYRIGHT: (C)2009,JPO&INPIT
