Processing and manufacture are convenient and the vacuum generation and the breaking device using profile are suitable for the mass production. Moreover, the operation of the apparatus is convenient and repair are easy in the problem occurrence. The vacuum generation and breaking device comprise the hollow profile(11), the ejector pump(18), and right and left cover(13,14). The hollow profile is opened to both sides. One or more connection holes(15) are formed into the thickness direction of the wall. The second fluid path(20,20a,20b) of the wall forms into the longitudinal direction. The ejector pump is formed with the inlet port and outlet of the compressed air as the in both. The air nozzle is mounted on inside. And one or more through-holes are formed in the wall. The left cover includes the first supply hole and the second supply hole. The right cover is formed in order to be path extended from outlet to outside.
