发明名称 PIPE COUPLING
摘要 PROBLEM TO BE SOLVED: To provide a pipe coupling capable of easily and surely holding an anticorrosive means in a spigot part, without processing an anticorrosive member or the spigot part with a tool. SOLUTION: A holding part 10 has a holding surface 10c composed of a construction material elastically undeformable more than the anticorrosive member 9 and opposed to at least a part of an end surface of the spigot part 4 by sandwiching an end surface covering part 9a of the anticorrosive member 9, and an opposed peripheral surface 10e opposed to an inner peripheral surface 4b or an outer peripheral surface 4a of the spigot part 4 by continuing with the holding surface 10c, and are arranged in the peripheral direction of the anticorrosive member 9. The holding part 10 is installed in the spigot part 4 by using elastic restoring force in the radial direction for turning the opposed peripheral surface 10e to the inner peripheral surface 4b or the outer peripheral surface 4a of the spigot part 4, and holds a covering state of covering the end surface 4c of the spigot part 4 with the end surface covering part 9a of the anticorrosive member 9 by the holding surface 10c.
