の走行用操作レバー装置。 In a construction machine in which a traveling motor is disposed in the lower traveling body and a traveling control lever is provided in the driver's cab of the upper rotating body, the control lever is provided in the vicinity of the driver's seat in the driver's cab so as to be able to swing in a cross direction, and the control lever is operated. Left and right small levers are provided on the lever head, and each pilot valve is provided at the bottom of the operating lever, which can be switched by rotating the operating lever in a cross-swing direction and by rotating each of the left and right small levers. At the same time, when the operation lever is rotated forward, backward, left or right, or the left and right small levers are rotated, the construction machine moves forward, backward, left spin turn, right spin turn, or left turn. 1. A driving control lever device for construction machinery, characterized in that it is configured to be able to pivot rightward.
