Claims

[Scope of utility model registration request]

In an actuator in which operating pressure is introduced to one side of the diaphragm through an introduction pipe, a pressure introduction union is used in the introduction pipe, one end of which is fixed in an air-liquid tight manner to the housing of the actuator, and the other end is fixed to the actuator housing in an air-liquid tight manner. A pressure introduction pipe connection structure for an actuator, characterized in that the pressure introduction pipe is inserted into a hole in a housing of a pressure generating mechanism via an O-ring.
