To provide a water supply automatic cut-off device for a farm field capable of reducing labor and time for maintenance.SOLUTION: A water supply automatic cut-off device 3 comprises: a water gauge unit 4 for detecting increase of water level in a farm field 1 to a prescribed water level and being detachably installed in the farm field 1; and a valve body unit 5 installed in a water supply line 2 to the farm field 1. The valve body unit 5 comprises: a valve body 11 for opening and closing the water supply line 2; and closed position movement means 12 for moving the valve body 11 to a closed position for closing the water supply line, from an open position for opening the water supply line 2. Between the water gauge unit 4 and the valve body unit 5, a transmission body 13 for transmitting detection of the prescribed water level by the water gauge unit 4, and an actuation instruction body 14 for actuating the closed position movement means 12 based on the detection transmitted from the transmission body 13, are provided. The water gauge unit 4 and the valve body unit 5 are detachably coupled between the actuation instruction body 14 and the valve body unit 5.SELECTED DRAWING: Figure 1 【課題】メンテナンスの手間を軽減ことができる、圃場への給水自動遮断装置を提供する。【解決手段】給水自動遮断装置３は、圃場１に取外し可能に設置されてその圃場１内の水位の所定水位までの上昇を検知する水位計ユニット４と、圃場１への給水路２に設置される弁体ユニット５とを備える。弁体ユニット５は、給水路２を開閉する弁体１１と、その弁体１１を、給水路２を開放する開位置から閉鎖する閉位置へと移動させる閉位置移動手段１２とを備える。水位計ユニット４と弁体ユニット５との間には、水位計ユニット４による所定水位の検知を伝達する伝達体１３と、その伝達体１３から伝達される検知に基づいて閉位置移動手段１２を作動させる作動指示体１４とが設けられる。そこで、水位計ユニット４と弁体ユニット５とは、作動指示体１４と弁体ユニット５との間で、分離可能に連結される。【選択図】 図１
