To simply and accurately know a replacement time following abrasion of a chain guide plate for guiding a drive chain for driving lifting of a workpiece support base around a driving tooth wheel.SOLUTION: This liftable workpiece support device is configured such that a drive chain 30a bendable only to one side supports a workpiece support base on a vertical linear path 36 from one end connected to the workpiece support base to a middle part engaged with a driving tooth wheel 31a, a chain guide plate 47 for holding an inter-link roller 44 of the drive chain 30a rotated around the driving tooth wheel 31a between it and the driving tooth wheel 31a is disposed on the outside of the driving tooth wheel 31a, a mark 60 is displayed at a position separated by a fixed distance from the rotation path of links 42, 43 of the drive chain 30a to the outside on the side surface of the chain guide plate, and an opening 61 for viewing the mark 60 is provided to a side wall 52a on which the driving tooth wheel 31a is pivotally supported on the side of the chain guide plate 47.SELECTED DRAWING: Figure 9
【課題】ワーク支持台を昇降駆動する駆動チエンを駆動用歯輪の周りで案内するチエンガイド板の摩耗に伴う交換時期を簡単且つ的確に知ることが出来るようにする。【解決手段】片側にのみ屈曲可能な駆動チエン30aは、ワーク支持台に連結された一端部から駆動用歯輪31aに係合する中間部までの上下方向直線状経路部36でワーク支持台を支持するように構成され、駆動用歯輪31aの外側には、この駆動用歯輪31aの周囲を回動する駆動チエン30aのリンク間ローラー44を当該駆動用歯輪31aとの間で挟むチエンガイド板47が配設され、このチエンガイド板の側面には、駆動チエン30aのリンク42,43の回動経路から外側へ一定距離離れた位置に目印60が表示され、チエンガイド板47の側方で駆動用歯輪31aを軸支する側壁52aには、目印60を目視するための開口部61が設けられた構成。【選択図】図9
