Japanese Patent JPH0361527

B2

A method of producing a shaft having plate-like member joined thereto comprises the steps of forming a through hole in the plate-like member, forming an annular groove in the inner surface of the through hole of the member, making the surface of the annular groove rugged by knurling, forming an annular projection on a shaft the outer diameter of the annular projection being substantially equal to or slightly smaller than the inner diameter of the through hole of the plate-like member inserting the shaft into the through hole of the plate-like member so that the annular groove is positioned between both sides of the annular projection supporting the side of the plate-like member and an end portion of the shaft and pressing substantially the whole of the side face of the annular projection of the shaft so that a part of the annular projection of the shaft plastically deforms and flows into the annular groove of the plate-like member, whereby the plate-like member is rigidly joined to the shaft. The plate-like member may be cam piece.
