Abstract:
The present invention eliminates the need to change a coil case even when the height of an electromagnetic device changes. An electromagnetic device (6) includes a core body (5) including a plurality of iron cores (41 to 44), coils (51 to 54) to be attached to the iron cores, respectively, and coil cases (61 to 64) that at least partially cover the iron cores, respectively, to insulate the iron cores from the coils. Each of the coil cases is divided, in the axial direction of the core body, into two portions being a first coil case part (61a) and a second coil case part (61b).
