PURPOSE:To improve visional field of a working vehicle by a method in which a cabin with a front glass whose both ends are curved is provided on the side of a slewing base having a boom pivotally supported on its central front end in a horizontally rocking manner, and the oil-pressure pipe of the boom is connected with the oil-pressure pipe of the slewing base. CONSTITUTION:A boom 11 is attached to the center of the front end of an upper slewing body 3 in a horizontally rocking manner, and a cabin (operating room) 7 is attached eccentrically on the left side of the upper part of the upper slewing base 3. The cabin 7 has a front glass 8 whose left and right ends are provided with a curved face cut into the side wall side. An oil-pressure hose pipe 10 is set close to the right-handed cut-in portion of the front glass 8, and the steel pipe 13 of the boom 11 is connected nearly straightforwardly. The structure of the oil-pressure pipe can thus be simplified and visibility of operation can also be enhanced. |
