Abstract

The present invention provides an oil supply device for a sewing machine capable of stably supplying lubricant. The oil supply device (100) of the sewing machine has: an oil pan (10) as a lubricant storage part for storing lubricant supplied to each part of the sewing machine (200); An oil supply pump (20) as a delivery device for the lubricant in the disc (10); an upper shaft (30) as a rotating shaft for supplying lubricant to its interior by the oil supply pump (20); communicated with the inside of the upper shaft and Lubricant supply channel (40) for oil supply part; lubricant is supplied from upper shaft (30) to first and second oil core members (50a, 50b) of oil supply part by capillary phenomenon. By supplying oil to one end of the first oil core member (50a) from the first discharge hole (33) formed on the upper shaft (30), excessive oil supply when the sewing machine (200) stops can be prevented.
