PURPOSE:To simplify manufacture and to simplify a device necessary to movement in a pipe by forming an object moving within a pipe by using a breathable and openable bag body and a resilient filler, tightening and closing the opening part of the bag body to form a connection part to an object for conveyance within a piping, and moving the bag body by means of a negative pressure after the bag body is inserted in a piping. CONSTITUTION:A bag body 10 is a body for an object moving within a piping (an induction object in a piping) and formed of a flexible material having breathability. The bag body 10 has an opening part 10A, and the bag body 10 is filled with resilient fillers 11, such as sponge. The bag body 10 is caused to smoothly run and pass through a piping P by means of a negative pressure generated in the piping P. As a result, for example, a cleaner for non-domestic use can be used as a suction device required for movement within a pipe, and a work of this kind to convey within a piping can be simply and high-efficiently effected. |
