To provide a simple door structure of a cabin which facilitates a door closing operation by making air pressure inside a cabin chamber appropriate and can be manufactured inexpensively.SOLUTION: In a door structure of a cabin, a door 10 is rotatably mounted to an entrance 8b of a cabin 6 in a right-left direction, and a door outer periphery and the entrance 8b are closed through press-contact of a seal member 11 so that a cabin chamber can be opened and closed. A handle member 15 gripped and used by an operator in a sitting posture on a driver seat 5c is mounted to an inside surface of a door glass 10a of the door 10. A door-side ventilation port 10b communicating indoor and outdoor is provided at a portion of the door glass to which the handle member 15 is mounted, and a valve part 21, which allows indoor air to be freely discharged from the door-side ventilation port 10b based on an operation of gripping the handle member 15 and closing the door 10, is installed.SELECTED DRAWING: Figure 2
