PROBLEM TO BE SOLVED: To inexpensively and easily determine whether or not an earth circuit is normally formed in a device prepared to secure safety by inspecting the earth circuit of an oil feeder, allowed to be used also for existing oil feeders and allowed to be shared to a plurality of oil feeders.SOLUTION: A conduction detection device has clip parts (4a, 4b) on both end parts so that an earth terminal (19) is gripped by the one-end clip part (4a) and an oil feeding nozzle (21) is gripped by the other-end clip part (4b), and has a function for confirming conduction in a circuit from the oil feeding nozzle (21) up to the earth terminal (19). |
