PROBLEM TO BE SOLVED: To provide a handrail frame of a work bench capable of improving the strength of the handrail frame and allowing a worker to climb on/get off from a hatch below an upper crosspiece to a work floor.SOLUTION: The handrail frame of a work bench 1 includes: a pair of vertical frame rods 21; an upper crosspiece 22; and a middle rod 23 to enclose the periphery of the work floor 3. A hatch 25 for allowing a worker to get on the work floor 3 is provided below the upper crosspiece 22. The middle rod 23 is connected to the pair of vertical frame rods 21 being arranged so as to change the position between a closing position X in which the middle rod 23 is made closer to the upper crosspiece 22 to narrow the hatch 25 and an open position Y to get away from the upper crosspiece 22 downward to enlarge the hatch 25. |
