The airtightness can be improved. Thereby, a highly reliable door structure of the cab 6 can be realized.
- the bent portion 5b is formed in a shape that is disposed substantially inside the turning radius 17 of the turning body 2 that is defined to be equal to or smaller than the vehicle width of the traveling body 1 when the door 5 is in a fully open state. Therefore, even when the work is carried out with the door 5 fully open, the work can be carried out by properly turning the revolving body 2 without being affected by the provision of the bent portion 5b. .
- the front pillar 15 is provided with a recess 15a that accommodates the end portion 5b3 of the second portion 5b2 of the bent portion 5b when the door 5 is closed, when the door 5 is closed, Since the end portion 5b3 of the second portion 5b2 of the bent portion 5b provided in the door 5 is accommodated in the recess portion 15a of the front pillar 15, the end portion 5b3 of the second portion 5b2 is disposed outside the front pillar 15. This contributes to maintaining a turning radius 17 equal to or less than the vehicle width.
- the protrusion part 12a which protrudes outside rather than the opening surface 15 which forms the entrance / exit 20 of the cab 6 is only a part of the flange part 12 which comprises a step. Therefore, the protrusion 12a can be provided in the step without changing the outer shell shape of the cab 6. That is, the step size can be increased without increasing the turning radius 17. Thereby, while turning the revolving body 2 and driving the working device 3, it is possible to perform a desired work without any trouble, and it is possible to easily get on and off the cab 6.
- the protruding portion 12a of the flange portion 12 is covered by the convex portion 5a provided on the door 5, so that the entire step including the protruding portion 12a can be positioned in the cab 6. . Therefore, even when the mini excavator is disposed in a cold region where snow is generated, it is possible to prevent the snow from being frozen in the step including the protruding portion 12a. Therefore, the door 5 cannot be opened due to frozen snow accumulation, and the door 5 can be smoothly opened and closed.
- the operator cab 6 having the selected combination of the flange portion 12 and the door 5 can be easily realized without causing a design change in the basic structure of the operator cab 6.
- the bent portion 5 b of the door 5 forms an escape portion that prevents interference with the exterior cover 8 that forms the revolving body 2, so that the door 5 is damaged due to the opening operation of the door 5. And the damage of the exterior cover 8 can be suppressed, and a highly reliable mini excavator can be realized.
- the construction machine according to the present invention may be a hydraulic excavator that is larger than the mini excavator. As long as it has a door that can be opened and closed, a construction machine different from the hydraulic excavator may be used.
