To provide a mechanism to protect a hand other than the one holding the control lever from obstacles, on a workbench when a worker performs the lifting operation using the operating lever on the workbench for high places.SOLUTION: A workbench 1 comprises a vertical frame 3 arranged around a work floor 2 for a worker, a handrail 4 constructed between the upper end parts of adjacent vertical frames 3, 3, and a control lever 6 to control a lifting operation inside the space divided by the vertical frame 3 and the handrail 4. A handle 7 with a detector is installed at the position below the handrail 4 inside the workbench, and the detector has the function to switch between enabling and disabling lifting operation of the work bench 1 using the operation lever 6 and enables the lifting operation using the operation lever 6 when the worker grasps the lever.SELECTED DRAWING: Figure 1
