METHOD FOR MANUFACTURING SHAFT MEMBER CONNECTED TO A SINTERED PART AND INTERNAL COMBUSTION ENGINE CAM SHAFT

Document Type and Number:

WIPO Patent Application WO/2007/077880

Kind Code:

A1

Abstract:

Provided is a simple method for manufacturing a shaft member connected to a sintered part with a high positional accuracy and angle accuracy and with a high yield. By compressing and molding a metal power or an alloy power into a pressed powder body. When assembling the pressed powder body to the shaft member, a protrusion formed on the outer circumference of the shaft member is used so that a part of the pressed powder body is shaved away by the protrusion and the protrusion comes into the pressed powder body. Thus, the pressed powder body and the shaft member are assembled and then sintering is performed.
