行い得なくなる。In conventional wooden sewing thread bobbins, the end of the thread is inserted into a diagonal notch in the flange of the bobbin. A plastic bobbin in which a flange for sandwiching the end of the thread is molded separately from the bobbin body, and then the cylindrical part of the flange is press-fitted into the cylindrical part of the bobbin body and sandwiched between the flanges of the bobbin. It is publicly known. A so-called undercut is provided on the inner periphery of the cylinder mouth of the bobbin body to maintain the press-fit state between the thread stopper flange and the bobbin body, but when the mold is shaped into a shape, the shape of the undercut collapses. , the above-mentioned press-fitting state cannot be obtained in the product (as a result, the thread cannot be effectively secured during use of the bobbin).
本発明は上記欠点を解消することを目的とするものであ

前記突出筒部５に圧嵌することよりなものである。Next, in the method of the present invention, a locking collar 4 having a diameter smaller than the diameter of the flange is attached to the outer surface of the flange 2 of the bobbin body 1 in the figure.
A thread stopper is formed on a locked part 6a, which is connected to the outer periphery of the projected cylinder part 5 by several connecting parts 7, and whose inner light is locked to the locking collar. After the flange body 6 is molded together with the bobbin body l, the thread stopper flange body 6 is press-fitted into the protruding cylindrical portion 5.

射状に設けられた紐状細小片よりなり、糸止めフランジ
体６の被係止部６ａの内周と接続しているものである。As shown in the figure, the connecting portion 7 is made of string-like small pieces provided radially on the outer peripheral end of the protruding cylindrical portion 5, and is connected to the inner periphery of the locked portion 6a of the thread stopper flange body 6. It is.
