SOLUTION: The oil filler port unit comprises a base 2 including at one of ends a tubular portion 8 which can be screwed with an oil filler port and a flange 7 with a larger diameter than that of the oil filler port and formed with at least one elastically deformable projection 17a in the vicinity of a surface at the other end, a tapered opening surface 9 for leading a pump nozzle, teeth 18 to engage with the projection 17a and a guide member 3 equipped with a lid 4 which is biased to always seal the opening surface 9 and opened by insertion of the pump nozzle. The guide member 3 is assembled with the base 2 to be capable of rotating in one direction by the projection 17a and the teeth 18.
