CAM SHAFT AND METHOD OF MANUFACTURING THEREOF

摘要

A camshaft in which the outer peripheral surface of a shaft (13) is provided with an axial groove (14), and a fitting member (10) is connected to the shaft (13) by liquid-phase sintering under the state in which a projection (12) on the surface of a bore (11) in the fitting member (10) is fitted into the groove (14). The projection (12) in the bore (11) of the fitting member (10) is formed so that its cross-sectional configuration is smaller than that of the groove (14) in the shaft (13). Therefore there is no possibility that the fitting member (10) made of a green compact can be damaged during the fitting or sintering.
