Abstract

A driving device enables an elastic hose (1) having a tip portion to which a TV camera (6) and/or a reverse jet nozzle (5) are attached, to be smoothly introduced into a branch pipe (51), so that the inside of the branch pipe can be positively and easily inspected and cleaned from the side of a main pipe (50). In one embodiment, a driving device (10) for moving the elastic hose (1) backward and forward by the action of fluid pressure is constituted by a pressure hose/cylinder unit (11) in which the elastic hose is inserted, a pig/piston unit (13) attached to the outer circumference of the elastic hose (1) and sliding in the pressure hose (11), and a compressor (pressure fluid supplying unit) for alternately supplying compressed air (pressure fluid) into airtight spaces (S1, S2) formed with the pig (13) in the pressure hose (11). The driving device (10) moves the elastic hose (1) backward and forward always positively by a large constant driving force of not a conventional frictional force but the fluid pressure, so that even if the branch pipe has a plurality of curves, the elastic hose (1) can be always smoothly introduced into the branch pipe.
