A cam member is formed with an axial bore slightly larger than the outer diameter of a cam shaft so as to enable easy insertion of the cam shaft therein when forming an assembly. A recess is provided between the axial bore and the cam shaft and a joinder piece is inserted in the recess with solder being retained in the joinder piece so that upon heating of the solder with the joinder piece located within the recess means, the cam member and the shaft member may be affixed together.
