It can be attached by being fitted and attached to the peripheral grooves 26, 26 formed on the outer circumference of the opening end surface of the opening having a length equal to or less than a half circumference through the insertion port 27, and one-touch attachment is possible. .

The arm fixing cap 24 is formed with a mounting hole 28 for the piston 23 penetrating through the central portion thereof, and the lifting operation of the float 2 is transmitted to the piston 23 on both sides on the outer peripheral surface side thereof. Supporting pieces 30, 30 for supporting the arm 29 for projecting are projected. Arm 29
The pivot 32 is attached to the pivot holes 31, 31 of the support pieces 30, 30. Further, an arcade 33 is attached around the upper side of the mounting hole 28 connecting the support pieces 30, 30 to prevent the washing water leaking from the mounting hole 28 from scattering.

On the other hand, as shown in FIGS. 4 (a) to 4 (c) of FIG. 4, the piston 23 is a portion whose tip side abuts against the central portion of the diaphragm valve 13 and presses and urges it. A large-diameter portion 34 that is larger than the diameter of the mounting hole 28 is provided on the rear end face side. The upper part of the large-diameter portion 34 is curved toward the rear end, and the tip cam surface 29a of the arm 29 is engaged with and abuts on the curved portion 34a.

Further, as shown in FIG. 5, the diaphragm valve 13 has a step portion 35a of the cavity 35 of the ball tap body 12a.
