極の接着性がよくない欠点がある。In conventional starter motors, as mentioned above, after the field magnetic pole is adhered to the inner peripheral surface of the iron base of the yoke, the first coating film is formed on the outer peripheral surface of the yoke, which increases the reliability of the coating. For example, the coating film may peel off during a rust prevention test in which salt water is sprayed onto the coating film for 48 hours, and the adhesiveness of the field magnetic pole is poor.
