Claims

[Scope of utility model registration request]

In the rotor core and the rotating shaft inserted into the shaft insertion hole by caulking the vicinity of the shaft insertion hole of the rotor core, the rotor core is connected to the rotating shaft inserted into the shaft insertion hole on one end surface of the rotor core. The fixed side crimping jig is provided with a fixed side crimping jig that is received near the fixed side crimping jig, and a movable side crimping jig that presses the rotor core received by the fixed side crimping jig in the vicinity of the shaft insertion hole on the other end surface. An insertion hole provided for inserting one end of the rotating shaft into the caulking jig,
A caulking device for a rotor core, characterized in that a stopper, which the tip of the rotary shaft abuts, is provided so as to be movable forward and backward in the axial direction of the rotary shaft by means of a screw mechanism.
