Claims

[Scope of utility model registration request]

The pipe gripping mechanism is composed of a pair of pipe gripping mechanisms, each of which has a ring shape approximately concentric with the outside diameter of the pipe and is capable of gripping the pipe and moving in the axial direction of the pipe, and a drive mechanism that connects these mechanisms and allows them to move relative to each other. The connecting part between the mechanism and the drive mechanism can move freely along the circumference of the ring-shaped pipe gripping mechanism, and the drive mechanism can rotate relative to the pipe gripping mechanism, so that one pipe gripping mechanism can hold the pipe. 1. A traveling device outside a pipe, characterized in that it is configured to be able to move along a pipe by alternately repeating an operation of gripping the pipe and moving the other pipe gripping mechanism along the pipe.
