Abstract

PURPOSE: To contrive mountability of a cabin in a backhoe so that the cover of a bonnet provided at the rear of a swivel base can be opened and closed when the cabin is provided, in the backhoe whose swivel base is reduced in longitudinal size to make its turning radius as small as possible so that it can deal with a very small site. CONSTITUTION: In a backhoe having at the rear of its body a cover 17 that is supported in such a way as to be free to oscillate vertically with the front of its upper part as a fulcrum and to be freely opened and closed, and having a cabin 7, the rear of the cabin 7 is made to overlap with the cover 17. The cabin 7 is supported on the body in such a way that it can be tilted forward to permit the vertical oscillation of the cover 17.
