PURPOSE:To fix easily a guide device by pressing the tip of a turning lever against the inside wall of a pipe end port of a pipe to be inspected, or separating it, by a handle operation. CONSTITUTION:A roller 30 guides a cable guide 31, a handle 39 is rotated, and as a result, when a bolt 40 moves in the direction of the handle of a shaft 37, a turning lever 36 turns by using a detaining tool 351 as a supporting point, and a tip part 361 is raised. Accordingly, when the handle 39 is rotated, the tip of the turning lever 36 is pressed automatically and firmly against the inside wall of a pipe end port of a pipe to be inspected 11, and a device itself is fixed to the pipe end port part. When the handle 39 is rotated in the opposite direction, the device is separated from the pipe end port by turning of the turning lever 36. |
