ABSTRACT:
A cam shaft for engine is constructed such that the cam shaft driven by a crankshaft is rotatably supported at both ends by respective journal bearing boxes. Either one of the journal bearing boxes is fed with pressure oil from an oil pump to cause the oil pressure gathered within the journal bearing box to act upon the end face of the cam shaft so that the cam shaft is normally biased in a constant axial direction.
