A starter comprises a thermostat for detecting increases in the temperature of brushes and interrupting the energizing of the starter, and a heat conducting member secured to the thermostat for conducting the heat of one of the brushes, the heat conducting member being attached to the brush. The heat conducting member may also be formed integrally with a brush holder. The heat conducting member may additionally be secured to a bracket so as to hold a base therebetween. The heat conducting member may also be composed of a metallic material having superior thermal conductivity, and may be copper or brass. An electrically insulating sheet may be held between the brush holders and the base as heat insulating material for preventing the transfer of heat from the brushes to the base. An electrically insulating tube may also be interposed between the thermostat and a first leg of the heat conducting member.

1. An engine starter comprising:a starter motor for starting an engine, said starter motor including a brush and a brush holder; and a control circuit for controlling said starter motor, said control circuit including a thermostat for deenergizing said starter motor when the temperature of said starter motor exceeds a predetermined temperature; said engine starter further comprising: a heat conducting member, having a first end thermally coupled to said brush and a second end thermally coupled to said thermostat, for conducting heat from said brush to said thermostat, wherein said thermostat detects said heat conducted from said heat conducting member for deenergizing said starter motor.
