Zusammenfassung:PROBLEM TO BE SOLVED: To increase safety and efficiency of work for opening a curled part, without affecting the measurement precision to the curled part of the can lid.SOLUTION: A pusher 16 of an opener body 10 pushes a pair of jigs across a curled part of a can lid to pressurize between a top plate and itself. An outer jig has a slope with a different slope angle, and also an inner jig has a slope with a different slope angle. The curled part is gradually pressed by using slopes of an outer jig 27 and an inner jig, while reversing both open ends of each jig, and thereby the curled part is folded to an outer circumference side and opened.
