ABSTRACT:
A coaxial starter in which a motor armature rotary shaft, an axially slidable output rotary shaft having a pinion at its front end and a solenoid switch disposed behind the motor are arranged on a common aixs. A portion of an iron core of the solenoid switch is extended such that the iron core portion journals the armature rotary shaft and separates a space containing a brush and a commutator of the motor from an interior space of the solenoid switch, and that the iron core portion has mounted thereon, through an insulating material, a power source side stationary contact and a brush side stationary contact. Also disclosed is a core and contact terminal assembly for a solenoid switch, comprising a casing containing therein a coil with a bobbin, a plunger slidably inserted into a bush mounted within the bobbin and a disc-shaped core disposed at an axial end portion of the casing. A movable contact on the plunger is engageable with two stationary contacts, and portions of the disc-shaped core is removed so that main body portions of the two stationary contacts are disposed therein, and the main body portions of the stationary contacts together with some portion of the core are secured by embedding them into resin material.
