PURPOSE:To easily supply oil without detaching a lubrication tank from a machine body by reversing a pump for jetting oil in the lubrication tank from a lubrication nozzle from a lubrication oil carried can to the lubrication tank. CONSTITUTION:A pump 16 is provided with a suction pipe 26 extended to a lubrication tank 25 storing oil and with a pipe 28 extended to each lubrication nozzle 27. A check valve 29 is disposed between the pipe 28 and the lubrication nozzle 27. Another check valve 30 is disposed on this side of the check valve 29, and the check valve 30 is connected to a lubrication oil carried can 31. When a limit switch is turned on, oil is supplied to the lubrication tank 25 though the check valve 30 and the pipe 28. |
