点にして、何れか一方に揺動し、その結果信号発生時期
にばらつきが出るといった不具合がある。Conventionally, when fixing a signal rotor to a rotating shaft, the signal rotor is provided with a circular shaft hole and a notch that opens into the shaft hole, and the circular shaft portion of the rotating shaft is attached to the shaft hole. The spring pin is inserted into the notch so that it springs into engagement with the signal rotor and rotating shaft.
The position of the notch is set so that the elastic force against the rotation axis of the spring bin acts in the direction of the center line of the rotation axis, so the signal rotor will not spring due to the clearance between the shaft hole and the shaft. There is a problem in that the bottle swings in either direction using the abutting portion of the bottle against the shaft as a fulcrum, resulting in variations in signal generation timing.

By driving a spring pin into the notch, the edge of the inside of the shaft hole farthest from the notch is brought into contact with the edge of the inside of the shaft, and the signal rotor is pulled out so that it cannot rotate relative to the rotating shaft. Therefore, it is possible to fix the signal rotor using extremely simple means and prevent variations in signal generation timing.
