不具合もあつた。 2. Description of the Related Art Conventionally, some construction machines are provided with strong supports on the sides and top of the operator's cab in order to protect the operator in the event that the operator falls over during work. The above-mentioned driver's cab is generally called a lope skiab, but as shown in Figure 1, it has a structure in which a rectangular cylindrical column c is fixed to the side plate b of the driver's cab a, so that the window d on the side of the driver is However, it could not be made larger due to the restrictions imposed by the side plate b, which had the disadvantage of poor visibility. In addition, since this window d has a small area, it is jammed and cannot be opened or closed. Conventionally, a window that can be opened and closed is provided at the rear of the driver's cab and used for ventilation and communication with the outside world, but the rear window If the wipers were made to open and close, the area wiped by the wipers would be halved, resulting in a problem in which visibility would be significantly reduced during rain.

れている。 A window frame 16 is attached to the upper part of the side plates 2 and 3 located on the side of the one-way driver's seat 15. Above window frame 1
6 is the front and rear rigid frames 16a, 16b and the upper and lower horizontal bars 16c,
16d, and the front rigid frame 16a is connected to the above-mentioned support column 1.
The rear rigid frame 16b is fixed with screws 17 to the side plates 2 and 3 fixed to the front surface of the column 12 at the front and outside of the column 12, and the rear rigid frame 16b is fixed with screws 17 near the connecting part between the side plates 2 and 3 and the rear plate 5. There is. Further, two grooves 16e are formed inside the window frame 16, and window glasses 18 having approximately one-half the area of the window frame 16 are fitted into these grooves 16e in a sliding manner.

視界も確保できる。 As detailed above, this idea is based on the driver's cab body 1.
At the upper side of the driver's seat 15 provided inside, there is a front vertical stile 1.
6a is provided with a window frame 16 fixed to both side plates 2 and 3 in front of the support column 12 provided on the side of the main body 1, and a sliding window glass 1 is installed inside this window frame 16.
8, the field of view of the driver seated in the driver's seat 15 is greatly increased from the rear surface of the pillar 12 to the rear rigid frame 16b, as shown in Fig. 5, compared to the conventional one. , visibility to the side of the driver's seat 15 can be improved. In addition, since each window glass 18 can be opened and closed, ventilation inside the main body 1 is good and interaction with the outside is facilitated.
Since almost the entire surface can be wiped away by 0, rear visibility can also be secured.
