METHOD OF COUPLING TWO METALLIC MEMBERS ABSTRACT OF THE DISCLOSURE In coupling two metallic members such as a shaft and a disc, a method comprises the steps of: forming an annular groove on the joint face or the outer circumference of the metallic member having a greater deformation resistance among the two (e.g. the shaft); forming uneven portions on the bottom of the groove by knurling or the like; working the other metallic member (e.g. the disc) having a smaller deformation resistance near its joint face with such joint face opposing that of the other (e.g. the shaft) whereby to cause plastic deformation and cause a part of the disc to flow into the groove to couple the metallic members together.
