PROBLEM TO BE SOLVED: To provide a cab capable of widely opening surroundings of a prime mover covered with a seat-supporting stand while preventing a link mechanism such as a control lever installed in a control tower from becoming complicated. SOLUTION: A control tower 13 is fixed on a chassis frame 8. In a mutually coupling state of a seat-supporting stand 12 with a cab floor 14 they are supported by the frame 8 in a rotatable state around the center P of a shaft and a shakable changeover can be carried out as one body between an operating state where the stand 12 is coupled with the frame 8 to cover an engine 2 and a maintenance one where the stand 12 is separated from the frame 8 to open surroundings of the engine 2. |
