Abstract: A caulking method includes: determining a caulking depth which becomes equal to or larger than a necessary release torque that has been set in advance, determining a stroke amount of a push-in part which becomes equal to or larger than the caulking depth that has been determined; determining the stroke amount of a drive unit which becomes equal to or larger than the stroke amount of the push-in part that has been determined, and controlling the drive unit at a target control stroke amount that is equal to or larger than the stroke amount of the drive unit that has been determined but is smaller than the stroke amount of the drive unit at which the caulk part is damaged.
