い。[Effect of the Invention] In the in-vehicle turning hydraulic excavator, the front end of the cab is cut obliquely obliquely as viewed from above so that the cab is disposed within the vehicle width circle. An oblique front surface is formed, and in the prior art cab, separate sashes or glass are provided on the front surface of the cab and the oblique front surface, respectively. For this reason, the front width of the cab is narrow, and an opaque member such as H rubber is present at the boundary between the oblique front surface and the front surface. However, in the present invention, a front sash having a rectangular cross section as viewed from above is formed on a cab equipped with an in-vehicle turning hydraulic excavator and having an oblique front surface, and the front sash is positioned above the front of the cab. It was stretched over the oblique front surface.
As a result, the front surface and the oblique front surface are stretched with transparent glass, and there is no opaque member such as H rubber which hinders the driver's front view. Therefore, the front view of the driver is widened, and the forward visibility and safety can be improved. In addition, since the front surface and the oblique front surface of the cab are formed of a sash, the cab does not lose air permeability.
