Accordingly, a space between the tip of the bellows 22 and the fixed plate 25 does not become a constant value or below since it is limited by the stopper pin 26. On the contact part of a flapper 17 and the bellows 22, a tongue 29 is formed by a U-cut groove 28, and with this tongue 29, the tip of the feedback bellows 22 contact.
