割してフロント窓を設けている。2. Description of the Related Art In a construction machine such as a hydraulic excavator, a working machine is operated while looking at the working machine outside a cab. For this reason, a cab of a construction machine has conventionally been provided with a plurality of windows to widen the field of view. For example, as disclosed in Japanese Utility Model Laid-Open Publication No. 62-56862, windows are provided on both the left and right sides of the cab, and are also provided on the front and rear of the cab. Moreover, the front surface of the cab has a window over the entire front surface to widen the field of view. In the conventional front window structure, the front surface is divided into upper and lower parts to provide the front window.

るように工夫されている。7 and 8 show an example of a conventional front window structure. In FIG. 7, a front lower window 51 and a front upper window 53 are provided on the front surface of the cab 50. The front lower window 51 may be a fixed window that cannot be opened or closed, or a front lower window that can be opened and closed by rotating it forward and backward as shown in FIG. Further, the front upper window 53 is provided with the guide rails 5 which are continuous on the left and right sides of the front surface and the back surface of the ceiling.
4, rollers 55 provided on both sides of the front upper window 53 are configured to slide up and down along the guide rails 54 so that they can be opened and closed. As a result, the front upper window 53 is opened so that work can be performed under a good field of view.

た。FIG. 8A is a side view of the cab 50 as seen from the arrow AA. In FIG. 8A, the front upper window 53a shows a state in which the front upper window 53 is closed, and the front upper window 53b shows a state in which the front upper window 53 is opened. Since the space 57 behind the ceiling of the conventional cab 50 is narrow, the guide rail 54 cannot be expanded, and even if a large front window, for example, one window occupying the entire front surface is provided, it cannot be stored in the ceiling space. It was I had no choice but to divide the front surface into two front windows.

A part 59 of the field of view 60 is blocked by the lower frame 53d of the front upper window 53 or a crosspiece provided at the boundary between the front upper window 53 and the front lower window 51. Because of this, a blind spot 59 occurs in a part of the field of view 60 on the front surface,
There was a problem that it was difficult to work on the front side, especially on the lower side. Further, since the conventional front window structure is fixed and is not replaceably provided on the front windows of various sizes, it has been difficult to meet various demands of users.

There is no blind spot in sight. Therefore, it is possible to obtain an effect that the work can be easily performed. Also, as shown in FIG.
Since the front upper window 25 and the front lower window 27 can be mounted instead of the large front window 13, it is possible to provide the effect of providing the front window frame structure that meets the user's request. For example, if the lower part of the window glass is likely to be damaged as in the case of construction at a quarry site or the like, it can be easily replaced with two front windows. Moreover, it is possible to meet the needs of various users by making the sizes gradually exchangeable.

For example, the expansion of the rear space portion of the cab 10 is not limited to the case of expanding the ceiling space shown in FIG. 5 (or FIGS. 1 and 3), but the case of expanding the upper half portion (B) as shown in FIG. Alternatively, the present invention also includes the case of expanding the entire rear part. It should be noted that this also includes the case where there is a space for accommodating the large front window 13 even when it is not expanded. The fixing means of the stopper 21 for the roller 16 is not limited to the screw.
