ABSTRACT:
A bobbin case for a shuttle having a rotary hook in which a plurality of pins for connecting an upper portion made of metal and a lower portion made of plastic are flexibly connected to the lower portion such that the pins may be slightly inclined upon contact between the upper portion and the pins due to vibrations transmitted from the rotary hook to the upper portion, thereby preventing generation of noise.
