In a float valve device for a carburetor, in which a valve pin member 5 is provided in a shaft hole 4 of a valve body 1 through a spring 7 and one end thereof protrudes from the rear end of the valve body 1, the shaft hole 4 is inserted into the valve body. A small diameter part 3 opening at the rear end of the valve body 1 and a large diameter part 2 continuous to the small diameter part via a step, and an annular projection 10 continuous to the large diameter part 2 protruding from the front end of the valve body 1, The valve pin member 5, spring 7, and tip member 6 are sequentially fitted into the valve body 1 through the annular projection 10, and the radial convex portion 9 provided on the tip member 6 is provided on the annular projection 10. It is characterized by being press-fitted into the radial recess 8. FIGS. 2 and 3 show one example, in which the valve body 1 is made of synthetic resin, and the shaft hole 4 is made into a through hole during molding.
A valve spring 7 is housed therein, interposed between both members 5 and 6. Furthermore, the annular projection 10
A plurality of recesses 8, for example four, on the circumference are arranged in advance on the inner periphery, and corresponding protrusions 9 on the outer periphery formed in advance on the tip member 6 made of rubber, for example, are engaged with these recesses 8. Thus, the member 6 is provided with a retaining and rotationally preventing engagement.

部材５の応答性が向上できる等の効果を有する。 In this way, according to the present invention, the shaft hole 4 of the valve body 1 made of synthetic resin is formed into a small diameter part 3 opening at the rear end of the valve body 1 and a large diameter part 2 connected to the small diameter part 3 via a step. An annular projection 10 connected to the large diameter portion 2 is provided protruding from the front end of the valve body 1, and the valve pin member 5, spring 7, and tip member 6 are sequentially inserted into the valve body 1 via the annular projection 10. , the radial protrusion 9 provided on the tip member 6 is connected to the annular protrusion 1.
0, the valve pin member 5 and the tip member 66 can be easily attached to the valve body 1 made of synthetic resin, and the tip member 66 has a diameter Since the concave portion 9 in the direction and the concave portion 8 in the radial direction of the annular projection 10 are press-fitted and locked, the axial centerness between the conical tip portion of the member 6 and the valve body 1 can be maintained at a high density, and the shaft hole 4
Changes in internal pressure within the valve member 5 are released through the recess 8, which has the effect of improving the responsiveness of the valve member 5.
