2. Description of the Related Art Generally, in an excavator-type construction machine such as a hydraulic excavator, an upper revolving structure is rotatably supported above a lower traveling structure, and an operator controls the left front part of the upper revolving structure. However, some of these shovel-type construction machines have a turning radius of the upper revolving structure that is the vehicle width (left and right width of the lower traveling structure), such as what is called a rear ultra-small revolving type shovel. There are small models that are specified to fit within a slightly larger range (for example, within 120% of the vehicle width). In such a small model, the left side surface of the driver's cab is conventionally as shown in FIGS. 3 and 4.
It was formed in an arc shape that fits within the vehicle width H and substantially follows the turning radius R. In this case, the door 17 for the entrance and exit provided in the front half of the left side surface 16A of the operator's cab 16 is a sliding door that slides in the front-rear direction so as not to protrude from the turning radius R even in the released state. Has been adopted.

By the way, in the driver's cab, various operating devices such as operating levers, operating switches, and monitors are arranged on both left and right sides of a seat on which the operator sits. In order to improve habitability, it is desired to make the interior space of the cab as wide as possible. However, in the cab 16 in which the left side surface 16A described above is formed in an arc shape, the gap S between the control device 18 and the door 17 becomes narrower on the front side of the cab 16,
For this reason, when it becomes difficult to operate the operation lever 19 and the hydraulic lock lever 20 provided in the front part of the control device 18, or when it is desired to widen the lateral width of the seat 21 in order to improve the habitability of the operator, There is a problem that it is difficult to secure a gap S between the door 17 and the control device 18 for smoothly opening and closing the door 17, and there is a problem to be solved by the present invention.
