Claims

[Scope of utility model registration request]

A fillet roll processing device that hardens the processed portion by bringing a pressure roller into pressure contact with a processed portion of a crankshaft supported by a receiving roller and rotating the crankshaft, the pressure roller being a supporting roller; a holding member that displaceably holds the pressure roller via the backup roller; and a holding member that displaces the pressure roller integrally with the backup roller via the holding member. a drive mechanism for pressing the pressure roller against the workpiece; a detection means for detecting the amount of strain on the back-up roller; and a signal from the detection means is input to operate the drive mechanism in accordance with the amount of strain. A fillet roll processing device characterized by comprising a control circuit means for outputting a signal.
