Abstract
In an electromagnet (1) in which a lead wire (21a) is extracted through a through hole (33) from an annular coil member (2) placed in an annular groove (32) of an annular core (3), a spacer (5) is provided to make the annular coil member have a first portion spaced from the through hole in an axial direction of the annular core. The through hole is formed to a closed bottom surface of the annular groove. A thermal fuse (4) is located at a second portion of the annular coil member on a surface facing opposite to the closed bottom surface of the annular groove. The electromagnet is for use in an electromagnetic clutch.
