Abstract

PURPOSE: To prevent an increase in size of a starter, to improve strengths of bent parts of commutator bars and risers, to prevent a decrease in an output, and to form the side of the rise of the commutator in a special shape so as to improve the efficiency of a grooving work.
CONSTITUTION: Sides of risers are formed in stepped shapes 4a, 4b. Further, a tapered shape 4c, a recess shape 4d, etc., are formed.
