Claims

[Claims for Utility Model Registration] A bearing structure for a starter that drives a ring gear of an engine by a pinion gear connected to an electric motor, in which a soft elastic material is provided between a bearing hole formed in a casing and an outer race of a rolling bearing. and a retainer member made of a hard material are fitted, and the retainer member has a convex portion facing the inner circumferential surface of the bearing hole or the outer circumferential surface of the outer race with a small gap therebetween. A bearing structure for a starter, characterized in that it has a bearing structure.
