動片に揺動軸を中心とするモーメン１−を与えることに
より、１ｊ１１動片の先端部が刃体Ｊ、Ｃ部に圧接して
刃体を固定する構造を有し、特に、揺動片を揺動可能に
軸着するために両側板及び揺動片に軸孔を穿設し、この
軸孔に揺動軸を挿通して１．π動片を支持していた。。(Prior Art) A conventional pocket knife whose blade body can be folded between two side plates has a swinging piece as a means for locking the blade body in an open state, and uses the elasticity of a bony member to lock the blade body in an open state. By applying a moment 1- centered on the swing axis to the swing piece, the tip of the 1j11 moving piece comes into pressure contact with the blade parts J and C to fix the blade. In order to pivotally attach the pieces, a shaft hole is formed in both side plates and the swinging piece, and a swinging shaft is inserted into the shaft hole.1. It supported the π motion piece. .
このため、揺動軸の両端部が両側板の外面に露出するの

要があった。しかし、この揺動軸が取付けられる位置は
側板の背部であり、この部分の外面は握りやすくするた
め曲面に仕上げられているから研磨作業は熟練と長時間
を要し、ポケットナイフの量産のネックとなっていた。For this reason, both ends of the swing shaft are exposed on the outer surfaces of both side plates, and it is necessary to polish those parts in order to make both end faces of the swing shaft ΦIII smooth so that there is no difference in level with the outer surface of the side plates. there were. However, this pivot shaft is attached to the back of the side plate, and the outer surface of this part is curved to make it easier to grip, so polishing requires skill and a long time, which is the bottleneck for mass production of pocket knives. It became.
（発明が解決しようとする問題点）
従来品は、揺動片を支持するために両側板及び揺動片に

る。(Operations and Effects) The present invention has the above-described configuration, and when assembling the same, the two side panels 1. Parts other than the swinging piece 3 and the swinging shaft 8 are attached between the "-" and "-" parts. That is, in the embodiment, both side plates 1. ] The blade body 2 is rotatably pivoted between the two, the spacer is clamped and fixed, and one end of the elastic piece 4 is inserted into the insertion hole ]3 provided in the spacer. Thereafter, the swinging piece 3 with a swinging shaft is pushed along the guide groove ]O by inserting the swinging shaft 8 through the groove [5] until the swinging shaft 8 is supported by the bearing part 9. At this time, the blade is kept open, and the tip of the swinging piece is in contact with the upper edge of the base 5 of the blade, and the elastic piece 4 is in contact with the lower edge of the swinging piece. Push it to one side. By the following operations, the pocket knife of the present invention can stand upright.
したがって、揺動片３を揺動可能に支える揺動軸が側板
コ、１の外面に露出することがないので、ボケッ１−ナ
イフの表面の仕上げが容易であるという効果を奏する。Therefore, since the swing shaft that swingably supports the swing piece 3 is not exposed to the outer surface of the side plate 1, it is possible to easily finish the surface of the knife.
