SOLUTION: Flanges 3, 3 are formed at the upper and lower peripheral parts of a bottomed tube body 2 with an inner cavity 6 large enough for a looper thread bobbin 11 to enter, and an arbor hole 5 is formed at the center part of a bottom part 4. A cover body 7 is removably mounted on the upper part of the inner cavity 6.
