The present invention relates to a device for keeping the horizontality of a worktable capable of making only a worktable on which a worker takes horizontal in a process in which high place work on an inclined ground surface is performed. To include an elevating plate elevated for the high place work, one or more lower connecting brackets having lower connecting holes formed in a longitudinal direction are protruding from an upper part of the elevating plate. The lower connecting holes include a lower support part including a longitudinal direction hinge shaft; a worktable placed on the upper part of the elevating plate with a space and on which one or more upper connecting brackets having upper connecting holes including the longitudinal direction hinge shaft are formed in the middle; a worktable angle changing unit changing an angle of the worktable around the longitudinal direction hinge shaft to the elevating plate; and a manipulation control part controlling and manipulating the worktable angle changing part. The longitudinal direction hinge shaft is fixed to the lower connecting holes and rotates on the upper connecting holes, or rotates on the lower connecting holes and fixed to the upper connecting holes. |
