PROBLEM TO BE SOLVED: To avoid interference with the other member, and enlarge a degree of freedom of the setting of a control valve by arranging so that one face of the control valve is in the form of inclination of a turning base capable of being vertically rotated around the center of a shaft provided on a traveling device. SOLUTION: A turning base 7 is rotatably supported around the center of the shaft of a vertical direction on a bearing body provided on the center between right and left crawler traveling bodies of a traveling device, and a working oil tank 24 and a control valve 25 are arranged in front of a hydraulic pump 23 in the right side of the turning base 7. Mainly, a plurality of valve bodies 25A provided on the control valve 25 driving and controlling a hydraulic instrument are arranged in the inclined direction for the vertical direction in regard to the arrangement direction. Thereby the control valve 25 can be compactly arranged in a narrow space, and the attaching area of the control valve 25 on the turning base 7 can be made constant regardless of the number of the valve bodies 25A. In addition, since the control valve 25 is inclined, interference with the other member can be avoided, and a degree of freedom of setting can be enlarged.
