Abstract
PURPOSE:To allow a reaction force of a fastening force to directly act from a driving shaft to a fastening member by allowing one of the plates for nipping a diaphragm to be provided with a step part which contacts through a spring seat metal. CONSTITUTION:A driving shaft 31 which advances and retreats in the vertical direction is inserted and fixed at the center part of a diaphragm 7, and a controlled body is connected at the edge part on the opposite side to the insertion edge part. At the insertion edge part of the driving shaft 31, a diaphragm plate 35 and a pressing plate 36 are fixed on the driving shaft 31 by a bolt 33, and a spring seat metal 37 is springily installed between the pressing plate 36 and the head part 33a of the bolt 33. Therefore, the reaction force of the fastening force generated by the fastening of a fastening member in assembly directly acts onto the fastening member from the driving shaft 31.
