ABSTRACT:
An engine starter suitable to be used under severe corrosive conditions is disclosed, wherein the inner race of the ball bearing for supporting the pinion driving shaft is made of a martensitic stainless steel hardened by a heat treatment, which is effective in maintaining a good sliding contact between the inner race of the bearing and the pinion driving shaft. The balls of the bearing may be covered by a seal at both open sides thereof; further, the front open end of the pinion may be closed by a cap.
