ドル装置。An inclined surface or unevenly distributed protrusion is provided on the inner end surface of the jet needle support hole in the bottom wall of the sliding throttle valve, and a ring is fitted to the head of the jet needle, and one end surface of the ring is formed on the inclined surface or unevenly distributed protrusion. In a jet needle mounting device for a carburetor sliding throttle valve, the jet needle is mounted in a jet needle support hole in an inclined state by abutting the protrusion and pressing the other end surface with a spring. An annular groove having a diameter larger than that of the opening is provided on the inner circumferential surface near the opening, and an annular groove with a diameter of 18
At least a pair of notches are provided at 0° symmetrical positions, and an annular base with a diameter slightly smaller than the opening and one on the outer peripheral surface of the annular base are provided.
and a pair of protrusions slightly smaller than the notch provided at 80° symmetrical positions, and when the whole is pushed into the jet needle support hole and rotated while aligning the protrusions with the notch, the protrusion is rotated. A jet needle device characterized in that the end of the spring is pressed by a holder that is axially locked by the inner edge of the opening.
