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 4):
A manufacturing method for manufacturing a camshaft extending over three or more cylinders arranged in series in an engine, the method comprising:\n a step of separately forming a driving shaft and a plurality of tubular members which includes a tubular cam member including a cam part and form a cam tube when being integrated; a step of forming a male spline on an outer tubular surface of the driving shaft; a step of forming a female spline by performing broaching machining on an inner tubular surface of at least each tubular member which includes the cam member among the plurality of tubular members; and a step of connecting and integrating all of the plurality of tubular members to form the cam tube, wherein the step of forming the cam tube is a step in which, in a state where the driving shaft is inserted into adjacent tubular members, end potions of the adjacent tubular members are integrated with each other by press-fitting while fitting the male spline with the female spline.
