摘要： PROBLEM TO BE SOLVED: To provide a pig passage confirmation device capable of confirming whether a pig passes therethrough or not, and further obtaining a position of the pig.SOLUTION: A pig passage confirmation device includes: a mounting member 25 removably attached to a repair valve; a holding member 27 vertically movably provided to the mounting member 25 in a water-tight state; an insertion member 29 provided to the holding member 27 and inserted into a distributing pipe 1; and a twisted coil spring 31 showing passage of a pig along with an ascent of the insertion member 29. The insertion member 29 is energized downward by a coil spring 95 with respect to the holding member 27. A movement of another end 31b of the twisted coil spring 31 is regulated by an engaging part 77 provided to the insertion member 29 in an initial state. When the pig passes therethrough and the insertion member 29 is pushed up, the engaging part 77 also moves upward and the other end 31b of the twisted coil spring 31 moves, so that the passage of the pig can be confirmed.
