Abstract:

A rotary assembly and a method of manufacturing the rotary assembly. In the rotary assembly, an inner hole (31) for inserting a drive shaft (2) therein is formed in the cam piece (3) of a camshaft (1), and a plurality of grooves (34) extending in the insertion direction of the drive shaft (2) are formed in the inner hole (31). The drive shaft (2) is inserted into the inner hole (31) in the state of the inner hole (31) enlarged by heating the cam piece (3). When the inner hole (31) is re-shrunk in this state by cooling, the outer peripheral surface of the drive shaft (2) is pressed and raised by the inner hole (31), and fitted into the grooves (34). As a result, the cam piece (3) is firmly fixed onto the drive shaft (2).
