<P>PROBLEM TO BE SOLVED: To provide a device for operating inside a pipe that can pass through the inside of a small-diameter pipe with an elbow and accurately perform variable operations on the inside of the pipe. <P>SOLUTION: The device for operating inside the pipe is configured to be movable inside the piping (pipe line) 11, and connects at least a first operation unit 4 with a second operation unit 5 via a connecting member 2. The connecting member 2 includes: a first connecting part 2a formed of a shape-memory alloy in which a linear shape is memorized, and a second connecting part 2b formed of a shape-memory alloy in which a curved shape corresponding to the curvature of the piping (pipe line) 11 is memorized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
