Claims

[Scope of Claim for Utility Model Registration] (1) Iron core, electromagnetic coil surrounding the iron core, peripheral wall surrounding the outer periphery of the coil, bottom plate that magnetically contacts the iron core and surrounding wall to close the peripheral wall, on the opposite side to the bottom plate Similarly. In an electromagnetic chuck that has a partition wall that closes the peripheral wall and a face plate that contacts the outer surface of the i-wall, the partition wall has a shallow groove that follows the shape of the coil on the surface that contacts the face plate, and this groove has a water inlet and a face plate that contacts the outer surface of the i-wall. The face plate is connected to the outside of the electromagnetic chuck through a drain port, and the face plate has a plurality of parallel through grooves and a magnetic pole fitted in the grooves via a magnetic insulating material, and the face plate has an edge portion that connects the An electromagnetic chuck in which each magnetic pole magnetically contacts the outer periphery of the groove, and each magnetic pole contacts a partition wall inside the groove. (2) The electromagnetic chuck according to claim (1), wherein the partition wall is a single independent middle plate, and the bottom plate is integrally formed with the iron core and the peripheral wall. (3) An electromagnetic chuck according to claim (1) of the utility model registration, in which the partition wall is formed integrally with the peripheral wall and the iron core, and the bottom wall is separated from the iron core and the peripheral wall.
