しているのが一般的である。2. Description of the Related Art There are many parts in a sewing machine mechanism that require lubricating oil, such as a part where operation is intense. If lubricating oil is insufficient, operation may not be performed smoothly. For this reason, many sewing machines are provided with a refueling device so that these portions are constantly refueled. For example, in a shuttle portion of a sewing machine, lubricating oil is supplied to a fitting portion between the inner shuttle and the outer shuttle, and the outer shuttle relative to the inner shuttle is smoothly rotated. This oil supply system is provided with a pump that pumps up lubricating oil from an oil tank provided in the sewing machine bed and forcibly feeds the oil, or a hook oil supply point using the capillary phenomenon and surface tension between the oil tank and the oil supply point. In other words, there is a system in which the lubricating oil is transmitted through an oil core, and the lubricating oil is transmitted through the oil core to feed the oil from the oil tank at a hook oil supply point. The power of the pump used in these refueling systems is generally derived from the main shaft of the sewing machine.

Hook shaft 103a accompanying
Is determined by the rotation of. That is, the amount of oil supplied to the shuttle 103 is determined by the sewing machine driving speed. Therefore, in the lubricating apparatus 100 having the above configuration, there is a problem that the amount of lubricating oil to the shuttle 103 cannot be changed without changing the sewing machine driving speed. In order to cope with this, in the above-described configuration, the lubricating oil is pumped by the lubrication pump 104 and the lubricating oil is supplied thereto. By configuring the diameter of the oil drain pipe 106 in the above configuration to be adjustable, it is possible to change the amount of lubrication to the lubrication point (the hook 103) without changing the rotation speed of the shuttle shaft driven by the sewing machine drive. Can be considered. However, in such a configuration, the lubricating oil is supplied to the oil tank 102 by the oil supply pump 104.
When the water is sucked up, foreign matter (dust) mixed in the oil tank 102 is also sucked up and clogged at a portion where the diameter of the pipe is adjusted, so that the diameter cannot be adjusted accurately, and the oil is supplied to the oiling point (the hook 103). The amount may not be adjusted well.
