とする高所作業車のレベリング装置。[Scope of Claim for Utility Model Registration] A leveling device for holding the work platform horizontally in an aerial work vehicle having a work platform attached to the tip of a boom that can freely raise and lower, expand and contract, etc. so as to be able to swing up and down. A leveling cylinder that swings the workbench up and down, a leveling controller that controls the swinging position of the workbench by controlling the operation of the leveling cylinder, and a raising and lowering operation means that raises and lowers the boom. The leveling controller controls the rocking position of the leveling cylinder so that the work platform is horizontal when the boom is not being raised or lowered by the raising or lowering operation means, When the boom is being raised and lowered by the means, the leveling cylinder is configured to control the rocking position so that the work platform is tilted at a predetermined angle in a direction opposite to the raising and lowering direction of the boom with respect to a horizontal surface. A leveling device for aerial work vehicles, which is characterized by:
