Abstract
A locking portion is attached on a curved tube portion of a measurement tube, and a hole portion is formed at a distal end of the locking portion in a vertical direction, and a conical depression is provided on an inner wall surface on outside of the hole portion. A coupling ring of a coupling portion engages the hole portion, and a pivot needle, coming into abutment with the conical depression abuts from an inner wall surface of the coupling ring which faces the conical depression. The other end of the coupling ring is elastically attracted toward a fixing portion via an elastic member formed of an extension spring.
