PURPOSE:To oil a trolley line without causing blinding in an oiling hole by providing a support member for keeping a tube and the trolley line in a prescribed interval and holding oil in a space between the tube and the trolley line in a non-oil feed state. CONSTITUTION:An electromagnetic pump 7 is driven by a timer control circuit 8, whereby oil in an oil reservoir 6 is discharged into a tube 9 to oil a trolley line 4. The tube 9 is disposed on the upper part of the trolley line 4, and connected with the trolley line 4 with use of a fastening 23. Since for the tube 9, a tip 50b of a support member is brought into contact with the upper surface of the trolley ine 4 and fixed, an interval between the tube 9 and the trolley line 4 is kept constant. The interval is proper for holding oil therein. Therefor, the oil is maintained in the interval part owing to surface tension of the oil at the time of non-oiling to permit dust from the outside to adhere on the surface of the oil. Accordingly, the dust can not reach an oil passage and thus block it. |
