Claims

[Claims for Utility Model Registration] (1) In a connection structure that connects a diaphragm assembly that opens and closes a flow path to the end of a plunger that is reciprocally driven, a rigid shaft in which is embedded, and an enlarged diameter head is provided at the end of the exposed part of the rigid shaft from the diaphragm,
A connection structure for a diaphragm and a reciprocating plunger, characterized in that a holding arm is provided at the end of the other plunger for inserting and removing the enlarged diameter head in the radial direction. (2) In paragraph 1 of the claims for utility model registration,
The plunger is biased in a direction to protrude from the actuator housing, and the holding arm is exposed at the protruding end of the diaphragm and the reciprocating plunger connection structure. (3) Scope of claims for utility model registration, paragraph 1 or 2
2. The connection structure for a diaphragm and a reciprocating plunger, wherein a pressing plate is further provided between the diaphragm assembly and the plunger to press the diaphragm of the diaphragm assembly against the valve seat when the plunger moves in the valve closing direction.
