Abstract
The present invention relates to a method for fixing an annular element onto a shaft. The shaft may be a camshaft and the annular element may be a cam piece or a journal piece used in an automobile. The annular element is fixed onto the shaft by: engaging an axially extending projection of the element with an axially extending groove of the shaft so as to prevent a relative rotating motion; deforming an outer wall of the shaft adjacent to said groove at two positions near the terminating ends of the projection so that the outer wall protrudes into the groove, thereby fixing the element onto the shaft.
