In a magnetic switch for a starter motor, a magnetic core member providing a magnetic flux path is composed of separate components: a first core, a cylindrical yoke and a second core, all contained in a cup-shaped frame in close contact to one another. The first core is forcibly inserted into the cup-shaped frame, and the cylindrical yoke formed by rounding a flat plate into a C-shaped body having a small opening is also forcibly inserted in the cup-shaped frame by squeezing the small opening. The separate components are firmly pressed to each other by an axial force generated by caulking an open end of the cup-shaped frame. A switch cover is connected to the magnetic core member not to loosen the axial force connecting the components. Thus, magnetic resistance increase in the magnetic flux path formed by separate components is effectively suppressed. |
