PROBLEM TO BE SOLVED: To provide a device for operating a jetting nozzle, which is structured so that a jetting nozzle part can be rocked and movable and is also effective for improving the operation speed or the control accuracy. SOLUTION: A spline shaft 1 driven to be rocked by a rocking driving mechanism 3 and a screw shaft 2 driven to be rotated by a rotary driving mechanism are arranged in parallel, the jetting nozzle 15 is formed to be moved by the rotation of the screw shaft 2 through a 1st gear 11 integrally formed with a 1st gear holder 10 engaged with the spline shaft 1 so as to be slidable and a 2nd gear 13 provided to be rotatable to a 2nd gear holder 12 engaged with the screw shaft 2 and to be rocked around the screw shaft 2 by the rocking of the spline shaft 1. The 1st gear holder 10 can be omitted by engaging the 1st gear 11 directly with the spline shaft 1.
