The left side portion of the circulation hole 2a, which is attached and through which the fluid flows, expands toward the outer pipe 1 side. The connection fitting 2B is also provided with a flow hole 2b through which the fluid flows.

Reference numeral 4 denotes a holding plate as a holding tool, which is attached to the other end of the outer pipe 1 on the downstream side in a sealed state together with the connecting fitting 2B via a packing 3, and has a plurality of flow holes 4a through which the fluid flows. It is provided on concentric circles. Reference numeral 5 denotes a bar magnet body, which includes a plurality of spacers 6 made of a ferromagnetic material, a plurality of permanent magnets 7 magnetized in the axial direction, and a non-magnetic material which covers the spacers 6 and the permanent magnets 7 in a hermetically sealed state. The permanent magnet 7 is covered with the non-magnetic body 8 in a state of being in close contact with each other via the spacer 6 so that the permanent magnets 7 repel each other. Then, one end of the bar magnet body 5, that is, the one end on the downstream side of the non-magnetic body 8, is attached to the center of the surface of the holding plate 4 on the outer pipe 1 side so that the bar magnet body 5 is coaxial with the outer pipe 1.
