Abstract:
Multiple tubular members  40  that include multiple cam members  41  and  42  having cam parts  11  are connected to each other to form a single cam tube  12.  Multiple female splines  45,  which are partially arranged on an inner tube surface  44  of the tubular members which include the cam members  41  and  42,  mate with male splines  47  formed on the outer tube surface  46  of a drive shaft  13,  and the cam tube  12  rotates integrally with the drive shaft  13,  and is capable of moving freely in the axial direction thereof.

Claim (Index 1):
A camshaft extending over three or more cylinders arranged in series in an engine, the camshaft comprising:\n a plurality of cam parts each having a plurality of cam profiles having different shapes from each other with respect to one intake or exhaust valve; one tubular cam tube on which the plurality of cam parts is arranged to be spaced apart from each other in an axial direction; and one driving shaft inserted into the cam tube, wherein the cam tube is configured by connecting a plurality of tubular members which includes a tubular cam member including the cam part to each other, wherein a female spline is arranged on an inner tubular surface of at least each tubular member which includes the cam member among the plurality of tubular members, and a plurality of the female splines are partially arranged in the axial direction of the cam tube on an inner tubular surface of the cam tube, wherein a male spline is arranged on an outer tubular surface of the driving shaft, and wherein, in a state where the driving shaft is inserted into the cam tube, the plurality of female splines and the male spline are fitted to each other so that the cam tube is configured to rotate integrally with the driving shaft and be movable in an axial direction thereof.
