PROBLEM TO BE SOLVED: To provide a cab realizing making of the cab to component and solving breaking of a pipe and energy loss by shortening the pipes between respective air conditioners. SOLUTION: A compressor 41, a capacitor 42 and a receiver 43 are arranged on a cab roof part 14r of a cab body 14a. An air conditioning unit 21 is arranged on a back surface part 14b of the cab body 14a. The air conditioning unit 21 has an evaporator 46 for cooling peripheral atmosphere by vaporizing a coolant fed from the receiver 43 and an electric heater 47 for heating the peripheral atmosphere and feeds air-conditioned air temperature-adjusted by these into the cab body 14a. A rear frame 55 for supporting the cab roof part 14r is hollow at the cab rear part and the pipes 53, 54 for communicating/connecting the compressor 41 and the receiver 43 of the cab roof part 14r to a lower air-conditioning unit 21 are arranged at the inside of the rear frame 55.
