Claims

[Scope of Claim for Utility Model Registration] A portion of the lubricating oil pumped out from the oil tank by a pump is supplied to the hook via a hook shaft that rotates the hook, and the remaining lubricating oil is supplied via an oil drain pipe. In the oil supply device for the sewing machine that collects the oil in the oil tank, the lubricating oil is disposed in a part of the oil drain pipe so as to be rotatable in the coaxial direction of the hook shaft, and the flow rate of the lubricating oil flowing through the oil drain pipe by rotating is provided. A sewing machine oil supply device characterized by being equipped with a flow control valve that controls.
