Reference numeral 1 denotes a looper guide metal, which is fixed to the sewing machine frame, and the looper guide 8 is inserted into the hole 1a of the looper guide metal 1 together with an O-ring 9 which is loosely fitted in advance into a groove 8b formed in the looper guide 8. Ru.
Reference numeral 2 denotes a guide cover, which is covered with a screw 3 to prevent the looper guide 8 loosely fitted into the looper guide metal 1 from coming off. Reference numeral 4 denotes an upper looper, which is inserted into the looper rod 10, adjusted to an optimal position with a collar 5, and fixed with a screw 6. Reference numeral 7 denotes an oil wick, which is inserted into a hole 8c provided in the looper guide 8 as shown in FIG. The looper rod 10 is supplied with oil by a small amount of oil-impregnated oil wick coming into contact with the looper rod. Reference numeral 8 denotes a looper guide, and a groove 8b is formed concentrically in the through hole 8a, and an O-ring 9 is fitted into the groove. As mentioned above, the O-ring 9 is an O-ring that is inserted into the groove 8b formed in the through hole 8a of the looper guide 8. 7 has the effect of preventing oil supplied in a small amount from leaking to the outside. 10 is a looper rod, which is not shown here,
The rotational movement of the sewing machine main shaft transmitted to the looper mechanism via the coupling mechanism is adjusted and fixed to the looper rod 10 by the movement of the outer periphery of the looper guide 8 and the sliding movement of the hole 1a of the looper guide metal 1. The vertical and horizontal swinging motions are transmitted to the upper looper.

The present invention has a through hole 8 in the looper guide 8 as described above.
By inserting the O-ring 9 into the groove 8b concentrically with the groove 8a and surrounding the opposing inner side 9a of the ring 9 and the outer periphery of the looper rod 10, the overlock sewing machine can operate at ultra-high speed. It is truly remarkable that oil leakage is extremely easily prevented during operation, and there is no chance of staining sewn products or producing defective products due to oil splashed onto the sewing fabric.
