To provide a male blade device capable of suppressing repair cost.SOLUTION: A male blade device 1 comprises: a roller 10 that rotates about an axis Lx; and at least one blade part 20 fitted to the roller 10 to caulk a metal plate MP. The blade part 20 includes a fixing part 21 fixed to the roller 10, and a blade tip part 22 detachably fitted to the fixing part 21 to protrude outside from the outer peripheral surface 13f of the roller 10 in a radial direction. When the male blade device 1 is seen along the axis Lx, the tip 22T of the blade tip part 22 is shifted closer to the rotational direction R1 side of the roller 10 than a center in the width direction W of the blade tip side 22.SELECTED DRAWING: Figure 3 【課題】 補修コストを抑え得る雄刃装置を提供することを目的とする。【解決手段】 雄刃装置１は、軸線Ｌｘ回りに回転するローラ１０と、ローラ１０に取り付けられて金属板ＭＰをかしめる少なくとも１つの刃部２０と、を備え、刃部２０は、ローラ１０に固定される固定部２１と、固定部２１に着脱可能に取り付けられてローラ１０の外周面１３ｆから径方向外側に突出する刃先部２２と、を含み、雄刃装置１を軸線Ｌｘに沿って見る場合に、刃先部２２の先端２２Ｔが刃先部２２の幅方向Ｗにおける中央よりもローラ１０の回転方向Ｒ１側にずれている。【選択図】 図３
