An oil drainage device having an oil drainage conduit 64 supported vertically at the tip of an oil conduit 63 and capable of adjusting the position in the vertical direction as described above and an oil drainage receiver 65 provided at the tip thereof is provided. It was used in vehicle maintenance yards where the amount of oil drainage was relatively large.

However, in the former oil drainage receiving device, since the temporary storage tank 52 is placed at the foot of a maintenance operation, it is extremely difficult to work directly below the oil drainage plug, and thus the working posture is unreasonable. Was. In addition, a problem common to the former and latter oil drainage receiving devices is that the operation of raising and lowering the oil drainage conduit 53 or 64 is performed by holding the oil drainage conduit 53 or 64 and by stopping the stopper of the oil drainage conduit 53 or 64. Both hands were required to loosen them, and the oil drain conduits 53 or 64 and the oil drain receivers 54 or 65 were slippery because oil was attached, making this operation even more difficult.

As another problem, the latter oil receiving device needs to stably hold the base end portion 61 due to the structure of the latter device. It must be installed in the pit below the floor of the site. However, the depth of the pit must be greater than the height of the workers, and therefore a waterproof layer for groundwater countermeasures must be interposed in the floor concrete. Anchor bolts that penetrate cannot be used, making installation work difficult.
