により取付けられる。[0009] The outer surface 2a of the driver's cab 2 is formed into a vertically elongated opening 2b having a wider width than the conventional one (the height is the same as the conventional one) by using a circular arc, in order to attach the door 3 to the front half of the outer surface 2a. The rear half is formed on the side wall 2c. The driver's cab 2 is located on the inside upper part of the outer surface 2a of the driver's cab 2 near the ceiling.
An upper rail 4 having a predetermined length and having a groove-shaped cross section and a curved longitudinal direction is provided in the horizontal center of the roller, and a similar lower rail 5 is located at the front side of the upper roller 4 at the inner lower part. It is set up like this. Further, a groove-shaped center rail 6 is provided in the center of the side wall 2c along the horizontal direction. On the other hand, the door 3 is formed in a size that is one size larger than the opening 2b, and has an upper roller 7 at the center of the inner upper part thereof, which has a roller 7a at its tip that engages with the groove of the upper rail 4. is provided, and the lower array is provided at the inner lower front end.
A lower roller 8 having a roller 8a that engages with a groove in the roller 5 is provided. Furthermore, a center roller having a roller 9a that engages with the groove of the center rail 6 is provided at the inner center rear end.
La 9 is provided. Therefore, the door 3 is connected to the driver's cabin 2 by each roller 7a, 8 as shown by the two-dot chain line in FIG.
A, 9a are attached by engaging with each rail 4, 5, 6, respectively.

止している。Next, the operation will be explained. When opening and closing the door 3 with respect to the driver's cab 2, the door 3 is opened and closed in a trajectory as shown in FIG. That is, when closing the door 3, the front end of the door 3 is moved parallel to the side surface 2a of the driver's cab 2 and gradually brought into line with the side surface 2a of the driver's cab 2. Therefore, when opened, the arcuate surface of the outer surface 2a of the driver's cab 2 and the surface of the door 3 overlap, and are accommodated within the turning radius R as shown in the figure. Of course, such a move is
Roller 7 is attached to the upper rail 4, and center roller 9 is attached to the center rail.
The lower roller 8 engages with the lower rail 5 and is regulated in the horizontal direction. In the figure, 10 to 15 are male or female strikers that fix the door 3 in its position and prevent it from moving left and right when the door 3 is closed or opened, and 16 and 17 are door locks. It is. In addition, each lane
The details of the engagement structure between the center rail 6 and each roller will be explained using an example of the center rail 6 and the center roller 9. As shown in FIG. 4, the center rail 6 has a guide 6a, and The center roller 9 has a guide roller 9b and a roller 9a, and the roller 9a receives the load when the door 3 moves. It has a swinging function to prevent the door 3 from coming off from the driver's cab 2.

も無くすことができる。Effects of the Invention As explained above, the present invention forms the side surface of the operator's cab, which is opposite to the boom of a working machine mounted on a swivel base, into a convex circular arc including the door. A rail is provided on the side of the cabin, and the door is provided with a roller that constantly engages with the rail and slides the door so that it can be opened and closed. Since it is provided within the swivel radius of the swivel base, the interior becomes larger, and therefore the width of the door can also be increased. This makes it easy for the operator to enter and exit the vehicle, and even when the vehicle is opened, it is within the turning radius of the vehicle, thereby eliminating the risk of interference with obstacles that conventionally occur when turning.
