摘要： PROBLEM TO BE SOLVED: To easily interpose a roller while facilitating determination of a dimension of a pocket inner periphery, eliminating a recession on a roller end face, and dispensing with gap adjustment after interposing of the roller in a punching cage for regulating coming-off of the roller by both pillars and a coming-off preventing member of a flange. SOLUTION: The coming-off preventing member 46 is constituted by a bent piece on a distal end of the flange 45, and is plastically deformed to overlap with an outer peripheral part of the roller 3 from an outer side with a gap (g) therebetween. When the outer peripheral part of the roller 3 is brought into contact with the coming-off preventing members 46, 46 adjacent in a peripheral direction from the inner side, and the roller 3 is pushed and slid to one end side from the tilt state of being placed on an annular part 42 on the other end side, one end side of the roller 3 is raised up, and a space between the coming-off preventing members 46, 46 are elastically enlarged. An effective part 46a of the coming-off preventing member 46 is gradually reduced in the peripheral direction from a maximum width position p1 to a most other end position p2 on the other end side. A low bending rigidity part 46c is formed on the other end side compared to the effective part 46a. An interposing groove 42b is formed on the annular part 42 on the other end side.
