Claims

[Scope of utility model registration request]

In a diaphragm actuator that follows the swinging motion of the rod and absorbs the vibration of the housing by disposing a bearing member on the rod that extends outside the housing through the rod penetration part of the housing, both end faces A slit 21d is formed in the innermost annular groove 21c of at least one annular groove 21c formed in at least one of the bearing cylinder body 21, and a slit 21d is formed in the radial direction from the rod insertion hole 21b.
A diaphragm actuator characterized in that a bearing member 20 includes:
