Abstract

PURPOSE:To make smooth pulling-out of a screw through a driving member, by a method wherein a base end face of the screw abuts against the inner bottom of a spline shaft part in a state of a recessed part, and a socket fitting of a press member fitted over a neck part of the screw is performed over a concentric circle to a driving member. CONSTITUTION:A thin diameter neck part 17 and spline shaft part 23 possessing a large number of cog parts lined up in an axial direction are provided on a base end side of a screw 1. A base end face 22 of the spline shaft part 23 abuts against the inner bottom 21 of the spline shaft part 20 formed on a driving member 5 and curing treatment 24 is performed in the vicinity of the foregoing base end face 22 through a device, for example, of hardening. Press plates 18a, 18b which have been obtained by splitting into two is fitted over the external circumference of the neck part 17, and socket fitting of those press plates 18a, 18b are performed over a concentric circle to the driving member 5. Therefore, the base end face 22 of the screw 1, the inner bottom 21 of the spline shaft part 20 and an end face 17a of the neck part 17a can form correctly a right angle respectively with the respective center shafts.
