Claims

[Claims for Utility Model Registration] (1) A ball support portion consisting of an annular groove or three or more annularly arranged holes is formed on one of the opposing flat surfaces of the first and second receiving members in a clamped state. A ball bearing, characterized in that a ball supported by a ball support portion is interposed between the first and second receiving members, and both receiving members are held relatively rotatably. (2) The thrust bearing according to claim 1, wherein the ball support portion is an annular groove having an inclined surface that supports the ball. (3) The thrust bearing according to claim 1, in which the ball support portion includes three or more conical holes arranged in an annular manner. i4) The first and second receiving members are provided on the pinion moving cylinder of the starter motor and constitute a cam engagement groove of a shift lever that transfers and powers the moving cylinder, and either one of the receiving members The thrust bearing according to claim 1 or 3, wherein the outer end surface of the thrust bearing forms the abutment surface of the cam. (5) The first and second receiving members constitute an annular labyrinth seal mechanism between them. thrust bearing.
