Claims

[Scope of utility model registration request]

(1) A sliding throttle valve that is slidably received in a guide hole and has a needle valve vertically disposed at the bottom thereof, and a pin shaft that is pivotally supported by the sliding throttle valve to pivotally support a link. In the sliding throttle valve type carburetor, the pin shaft is provided with a small diameter portion, and the needle hemi is prevented from being removed in its proximal direction by the bottom of a set plate that is approximately U-shaped; One side plate of the set plate comes into contact with the inner wall of the sliding throttle valve, and the engaging portion formed on the other side plate engages the small diameter portion of the pin shaft, thereby aligning the pin shaft with its axis. The set plate is prevented from being pulled out in the direction, and the set plate is elastically fitted into the sliding throttle valve by generating an outward elastic force between the side plates. Sliding throttle valve type vaporizer.

(2) The sliding throttle valve type carburetor according to claim 1, wherein the retaining portion has a concave shape complementary to the small diameter portion.

(3) The sliding diaphragm according to claim 1, wherein the engaging portion has a convex shape that prevents the set plate from being removed from the small diameter portion. Valve type vaporizer.
