Abstract

A pressure damper has a main body with a recessed section for storing liquid. A thin film is mounted to the main body so as to hermetically seal the recessed section. A reference member is arranged in the recessed section of the main body and is configured to be brought into contact with or separated from the thin film. A detecting unit is configured to detect, without contacting the reference member, a displacement of the reference member due to a pressure change of the liquid stored in the recessed portion of the main body.
