PROBLEM TO BE SOLVED: To provide a lifting magnet which can remove the foreign substances adhered to the surface of a lifted body easily.SOLUTION: In the lifting magnet 1, a shaft part 12 is slidable in a through hole 24 communicated to a gas compression chamber 11 and a first flange part 13 prepared on an end 12a side of the shaft part 12 is also slidable within the gas compression chamber 11. Therefore, along with the other end 6b of an inner pole 6 and the other end 7b of an outer pole 7 being closer to a lifted body W, when the shaft part 12 slides to the gas compression chamber 11 side pushed relatively by the lifted body W, the first flange part 13 slides also upward. Thereby, the gas in the gas compression chamber 11 is compressed in the first flange part 13. A gas sending part 16 can remove the foreign substances adhered to the surface of the lifted body W, by sending the compression gas between the other end 6b of the inner pole 6 and the other end 7b of the outer pole 7 and the lifted body W. |
