PROBLEM TO BE SOLVED: To provide an open channel regenerating member for actualizing reliable and easy water stop even when the axis of one open channel regenerating member is somewhat shifted from that of the other or the regenerating member is expanded or twisted. SOLUTION: A receiving part 5 of an elastic material and an insertion part 4 of an elastic material are provided on the longitudinal one-end outer peripheral face of the open channel regenerating member 2 and on the other-end outer peripheral face thereof, respectively, and a water stop packing 6 is mounted on the inner peripheral face of the receiving part 5 or on the outer peripheral face of the insertion part 4. During regenerating a plurality of open channels 1 when the open channel regenerating members 2 are arranged with the opposed ends 21, 22 approximately contacting each other, the receiving part 5 and the insertion part 4 are fitted to each other via the water stop packing 6.
