摘要：
PROBLEM TO BE SOLVED: To provide a method of manufacturing a stopper capable of suppressing deformation and damage of a cap member. A method for manufacturing a plug according to the present invention uses a first jig having a recess on an upper surface thereof so that an opening end side of a cap member projects above an upper surface of the first jig. A second jig having an arrangement step of arranging the member inside the concave portion of the first jig, and a through hole provided with a tapered portion, a small diameter portion, and a large diameter portion having a diameter larger than the small diameter portion in this order. Using, the fitting step of fitting the large diameter portion of the second jig to the protruding portion of the cap member, and the plug body is press-fitted inside the cap member from the taper portion side of the second jig. The taper part of the second jig is inclined so that the diameter becomes smaller toward the small diameter part of the second jig, and the maximum diameter of the plug body is the inner diameter of the opening end of the cap member. The diameter of the small diameter portion of the second jig is larger than the inner diameter of the opening end of the cap member. Remote small. [Selection diagram] Figure 1【課題】キャップ部材の変形及び破損を抑えることができる栓体の製造方法を提供する。【解決手段】本発明に係る栓体の製造方法は、上面に凹部を有する第１の冶具を用いて、キャップ部材の開口端側が第１の冶具の上面よりも上側に突出するように、キャップ部材を、第１の冶具の凹部の内側に配置する配置工程と、テーパー部と小径部と該小径部よりも径が大きい大径部とがこの順に設けられた貫通穴を有する第２の冶具を用いて、第２の冶具の大径部を、キャップ部材の突出した部分に嵌合する嵌合工程と、栓本体を、第２の冶具のテーパー部側から、キャップ部材の内側に圧入する圧入工程とを備え、第２の冶具のテーパー部は、第２の冶具の小径部に向けて径が小さくなるように傾斜しており、栓本体の最大径は、キャップ部材の開口端の内径よりも大きく、第２の冶具の小径部の径は、キャップ部材の開口端の内径よりも小さい。【選択図】図１
