An object of the present invention is to disperse a lubricating oil from a control pump mounted below a driver's seat without polluting a running vehicle in a vehicle for spraying a chemical solution provided with a center boom and left and right side booms on the running vehicle and equipped with a chemical solution tank. The task is to be able to take it. A spraying boom (50, 51, 52), a driver's seat (3), and a chemical tank (40) are mounted on a traveling vehicle body (2) supported by a front wheel (6) and a rear wheel (7). In a chemical spraying vehicle in which a control pump (30) is mounted on a control pump mounting member (5d) connecting the left and right frames (5L, 5R) of the traveling vehicle body (2) below the seat (3), waste oil of the control pump (30) is used. A chemical spraying vehicle provided with a waste oil shooter (12) for flowing oil to the lower side outside the control pump mounting member (5d) below the stopper (30c).
