ツチで成型する。 The guide pin 5 of the lower mold is attached to the sliders 7, 7 of the upper mold 6,
5 are fitted and the upper and lower molds are brought together, the inner ends 7a and 7a, which were initially separated, are joined and the upper and lower molds form cavities A and B. When molten synthetic resin or metal such as zinc alloy is injected into these cavities A and B and the upper mold is separated from the lower mold after it hardens, the inner ends 7 and 7 follow the inclined guide pins 5 and 5. The upper and lower molds can be separated from each other without damaging the shape of the locking pin 3 by opening left and right. In this way, the presser foot is molded in one touch.
こうして成型された押え金のホルダ８への取付
例を以下説明する。 An example of how the presser foot molded in this manner is attached to the holder 8 will be described below.

央に突設する支片２を着脱自在に嵌合する。 Reference numeral 8 shown in FIGS. 1 and 2 is a synthetic resin holder that connects the presser foot of the present invention in a detachable manner.A cut groove 9 is provided rearward in the front lower part of the holder 8, and an elastic holder facing the cut groove 9 is provided. The lower piece is divided into left and right parts, and a support piece 2 protruding from the center of the presser foot main body 1 is removably fitted between the left and right elastic divided pieces 10, 10.
そして切割溝９に面するホルダ８の上片８ａに
は支片２の左右に突出する係止ピン３を係合する
半円筒形の凹溝１１を設ける。 The upper piece 8a of the holder 8 facing the cut groove 9 is provided with a semi-cylindrical groove 11 that engages the locking pin 3 projecting from the left and right sides of the support piece 2.

係合して主体１をホルダ８に連結する。 Then, as shown by the arrow in FIG. 1, when the presser foot main body 1 of the present invention is moved with the tip of a finger and the branch piece 2 is fitted between the left and right elastic divided pieces 10, 10, the branch piece 2 guides the main body 1. At the same time, the left and right locking pins 3 are engaged with the grooves 11 to connect the main body 1 to the holder 8.
また押え金主体１を矢印と反対方向に引き出す
と、弾性分割片１０，１０はその弾性に抗して切
割溝９を開き、主体１をホルダ８より分離する。 Further, when the presser foot main body 1 is pulled out in the direction opposite to the arrow, the elastic dividing pieces 10, 10 open the cut grooves 9 against their elasticity, and the main body 1 is separated from the holder 8.
第２図に示すＴは定規棒である。 T shown in FIG. 2 is a ruler rod.
