を特徴とするダンプカーのオイルリザーバ。[Scope of Claim for Utility Model Registration] A dump truck in which a hydraulic cylinder is interposed between a vehicle body frame and a cargo box tiltably mounted on the top of the vehicle body frame, and the cargo box is tilted by the expansion and contraction movement of the hydraulic cylinder. An oil reservoir is fixedly installed on the side of the hydraulic cylinder, and the oil reservoir is connected by a first pipe to a pump communicating with the piston chamber of the hydraulic cylinder, and is also connected to the rod chamber of the hydraulic cylinder by a second pipe, and is connected to a pump communicating with the piston chamber of the hydraulic cylinder. The open ends of the first pipe and the second pipe connected to the reservoir are arranged so that the oil reservoir is always located in the oil even if the oil level in the oil reservoir changes as the oil reservoir tilts together with the hydraulic cylinder, and An oil reservoir for a dump truck, characterized in that a rectifying member is provided between the open ends of the first pipe and the second pipe to adjust the flow path of oil flowing from each pipe.
