To provide a thin tube maintenance and inspection apparatus which can improve working efficiency, can decrease the fatigue of a worker, can improve the work environment, has both a thin tube clamping function and a sealing function, and can carry out both the maintenance and inspection.

A plurality of cleaning guns are arranged on the same base plate, each cleaning gun being equipped with a gas/liquid pressure increase cylinder having a hollow piston rod. By the thrust force of the cylinder, a clamping collet attached to the tip of the piston rod is pressed via an elastic rubber arranged on the outer surface of the collet so that the outer surface of the rubber is pressed against the inner surface of a thin tube. Thus, the thin tube can be strongly fixed, the damage to the inner surface of the thin tube is prevented, and the leak of a cleaning liquid from the dividing plane of the clamping collet and from the contact section between the thin tube inner surface and the rubber to the thin tube opening side is prevented.
