Abstract

PURPOSE:To make a shaft and a crank pin in simple shapes to enable a separate finishing treatment and to aim at reduction of man-hours and a cost by making joining members in which a steel pipe made shaft and a crank pin are press-fitted respectively to abut each other and welding and joining them together. CONSTITUTION:Annular joining members 12, 13 are press-fitted on the outer circumferential portions of the ends of a steel pipe made shaft 8 and a crank pin 9 respectively and both joining members 12, 13 are forced to butt at each other and the outer circumferential portions are laser-welded or the joining faces are projection-welded and joined at the welding portion 14. Accordingly, a shaft 8 and a crank pin 9 are separately finishingtreated in simple shapes, machining jigs are simplified, and coorking man-hours and a cost can be reduced.
