Particularly in the case of a cartridge tank, kerosene is attached to the refueling cap, and your hands get dirty when you open it. Further, if the tank falls over during oiling, there is a disadvantage that kerosene will be spilled. Then, at the time of lubrication, the amount of kerosene that has been lubricated is constantly checked, and if the operation of lubrication is not stopped, the kerosene will overflow. Further, there is a problem in that kerosene spills from the tip of the lubrication hose when the lubrication operation is accidentally performed without putting the lubrication hose in the tank or the hose is pulled out during lubrication.

The present invention has been made to solve the above-mentioned conventional problems, and does not spill kerosene even if the tank falls during refueling without opening the refueling cap by hand or soiling the hand. The object of the present invention is to provide a safe lubrication oil supply in which a fixed amount of kerosene can be easily lubricated and the kerosene will not be spilled even if the lubrication operation is accidentally performed.

[Means for solving problems]

The lubrication device for oil-burning equipment of the present invention is made to achieve the above object, and the holder main body on the discharge side of the lubrication device is attached to the refueling cap of the cartridge tank to provide a space between the storage tank and the refueling cap. In an oil-filling device of an oil-burning device that forms an oil feed passage and an exhaust passage and fills a cartridge tank from a storage tank with the above-mentioned oil filling device, the holder main body is used as an oil supply cap between the holder main body and the oil supply cap. Restraint means that restrains and seals the connection between the oil supply passage and the exhaust passage between the holder body and the oil supply cap, and shuts off the oil inlet when the holder body is disconnected from the oil supply cap. And a means for shutting off the oil injection port.
