ン９を差し込んで、回り止めが図られる。When the fixing cap 6 is screwed onto the mouth and neck part 5 having such a configuration, as the fixing cap 6 is tightened, the outward 7 flange 4a of the liquid level detection device 4 moves toward the tip side of the mouth and neck part 5. It is pressed, and the 7 langes 3a of the flange packing 3 are compressed. As it is compressed, an elastic restoring force as a reaction force acts on the fixing cap 6 and the fixing cap 6
The tightening force increases. When the tightening force reaches an appropriate value, the notch 10 of the threaded portion 5a on the outer periphery of the mouth and neck portion 5 and the notch 13 of the threaded portion 6a of the fixing cap 6 match. The point at which the respective notches 10.13 match is visually confirmed by looking into the threaded portion 5a through the bottle hole 12. If they do not match, the bottle hole 12 is screwed around by the threaded portion 5a, so it is easy to confirm when they match. Each notch 1
When 0.13 matches, the anti-rotation bottle 9 is inserted through the via hole 12 to prevent rotation.
