。 An aerial work vehicle in which a boom with a bucket at the tip of the vehicle is attached to the vehicle behind the driver's cab so that it can rotate and raise and lower, particularly in a high-altitude work vehicle where the boom is moved in a retracted position with the boom tilted forward and backward of the vehicle. A ladder loading/unloading device used for a work vehicle, the base end of which is rotatably connected to one side of the vehicle, and a hydraulic cylinder is used to move the ladder between an upright position on one side of the vehicle and one side of the vehicle. A rotating frame configured to be able to be rotated between a hanging position hanging from the side and attachable to two places in the longitudinal direction of the ladder on the side thereof, and when the rotating frame is in an upright position, the ladder is attached to the rotating frame. In the case where the front part of the ladder is located above the driver's cab, the rear part of the ladder is inclined lower than the front part, and the width direction of the ladder is substantially along a vertical plane, A ladder loading/unloading device for an aerial work vehicle, characterized in that the direction of the rotational axis of the rotation frame is configured to be looser than the inclined state of the ladder.
