Claims

[Scope of utility model registration request]

A casing in which a measuring chamber is formed between an inlet and an outlet, a pair of rotors provided in the measuring chamber and rotating in proportion to the flow rate of the fluid to be measured, and each rotor rotatably supported. a pair of support shafts provided in the casing, at least one of the support shafts is formed by a hollow shaft, and a rotor supported by the hollow shaft is provided with a driving magnet. A shaft support fixed to the casing is inserted into the opening side of the hollow shaft, and the output shaft is rotatably supported by the shaft support, and the output shaft is provided with a shaft in synchronization with the rotation of the driving magnet. In the positive displacement flowmeter provided with a driven magnet that rotates the output shaft, the hollow shaft has a tapered surface formed on the inner peripheral surface at a position corresponding to the end surface of the rotor, and the shaft support also has the tapered surface. A tapered surface is formed on the outer peripheral surface at a position facing the tapered surface of the hollow shaft, and by pressing the shaft support in the axial direction, the tapered surfaces are brought into close contact with each other, thereby increasing the strength of the hollow shaft. A positive displacement flowmeter featuring:
