載のバツテリ用液口栓。[Claims for Utility Model Registration] (1) A liquid spout body that seals the liquid mouth of the battery body, and a liquid level that hangs down from the liquid spout body and detects the electrolyte level position by coming into contact with the electrolyte. In a liquid spout plug having a detection part, the liquid level detection part is made of a light-transmitting resin, and when the liquid port is sealed, the lower end of the liquid level detection part reaches at least the lowest liquid level position, and the upper end reaches the liquid level position. Penetrates the spout body and is exposed at the top of the liquid spout body,
In addition, the horizontal cross-sectional shape is an arc shape or a hollow circle shape, and a spirally inclined bottom surface is formed in which the contact position with the liquid surface is sequentially displaced in the circumferential direction as it moves from the lower end to the upper end. Features a liquid spout plug for batteries. (2) The battery liquid spout plug according to claim 1, wherein the spirally inclined bottom surface is formed at least from the lowest liquid level position to the highest liquid level position. (3) The battery liquid spout plug according to claim 1 or 2, wherein the liquid spout body and the liquid level detection portion are integrally formed of a light-transmitting resin.
