PROBLEM TO BE SOLVED: To provide an introduction device that can surely perform a work by a plurality of working bodies in a fluid pipe without applying load to cables connected to the working bodies when introducing the working bodies into the fluid pipe.SOLUTION: This introduction device includes: a body 2 mounted in a sealed state in the fluid pipe 1; the plurality of working bodies which are introduced into the fluid pipe 1 from the inside of the body 2 and are integrally configured to perform a prescribed work in the fluid pipe 1; and a plurality of cables which are connected to the working bodies 27 and 28 and include an operation cable 28a that can operate working directions of the working bodies 27 and 28. Further, the introduction device includes an introduction cylinder 25 to introduce the plurality of working bodies 27 and 28 into the fluid pipe 1. The working bodies 27 and 28 are arranged to project from one end side of the introduction cylinder 25. The plurality of cables are arranged to be extended to the outside from the other end side of the introduction cylinder 25 and can be delivered to the inside of the fluid pipe 1 or pulled back from the inside of the fluid pipe 1. |
