ることがあつた。Conventionally, for example, in an overlock sewing machine, a concave oil tank is integrally provided on the bottom plate forming the lower part of the sewing machine head, and the lubricating oil accumulated in the oil tank is supplied to each part of the sewing machine head by means of a supply pump. After being supplied to the mechanism part,
The excess lubricating oil is dropped into the oil tank and reduced. However, in sewing machines that rotate at very high speeds, the sewing machine head gradually warms up even though each mechanical part of the sewing machine head is lubricated with lubricating oil, and as a result, the bottom plate The lubricating oil in the oil tank is also heated, and the heated lubricating oil is supplied to each part of the sewing machine head.
Each mechanical part was not sufficiently lubricated, which resulted in damage to each mechanical part.

材によつて連結するようにした潤滑装置が案出された。Therefore, in order to overcome these drawbacks of the conventional technology, it has been proposed to separate the sewing machine head and the oil tank from each other and place them on the sewing machine table, and to connect the two with a connecting pipe having an oil passage. A new lubrication device was devised.
