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.
【課題】手摺枠の強度を高めることができると共に、上桟の下方の昇降口から作業床に容易に昇降できるようにした作業台の手摺枠を提供する。【解決手段】 作業台１の作業床３の外周に設置されていて、一対の縦枠杆２１と上桟２２と中桟２３とを有し、上桟２２の下方が作業床３に乗り込むための昇降口２５とされた作業台の手摺枠であって、一対の縦枠杆２１に、中桟２３が上桟２２に近づいて昇降口２５を狭くする閉鎖姿勢Ｘと上桟２２から下方に離間して昇降口２５を広くする開口姿勢Ｙとに姿勢変更自在に連結されている。【選択図】図３
