なるのを抑制しているのである。 In this second embodiment, the spring 4 moves the valve body 12
Even if the valve body 12 and the fixing member 13 are strongly pushed toward the fixing member 13, the distance between the valve body 12 and the fixing member 13 does not become smaller than a certain level due to the spacer balls 3, 3. It is never strongly pinched by the valve body 12 and the fixing member 13. Therefore, the seal plate 5
However, even if the valve body 12 and the housing 13 come into contact, the contact force is weak and the operating force required to rotate the valve body 12 does not increase. That is, the spacer balls 3, 3 suppress the operating force from increasing.
次に、第５図に本考案の第４実施例を示す。 Next, FIG. 5 shows a fourth embodiment of the present invention.
