PROBLEM TO BE SOLVED: To prevent excessive supply of lubricating oil to a guide rail, with simple constitution.SOLUTION: An oiling device for an elevator guide rail is provided which comprises: a case 31 that stores lubricating oil and moves up and down together with a lifting body; application members 41-43 that are supported by the case 31 so as to be movable from an initial position spaced from a guide rail 5 to an operation position contacting the guide rail 5; sucking-up members 51, 52, etc. that suck up the lubricating oil in the case 31 by capillary action and supply the oil to the application members 41-43; sliders 41-43 that are positioned contacting the guide rail 5 while being connected to the application members 41-43; and holding structure that holds each of the application members 41-43 in the initial position while the lifting body stops and while the lubricating oil is filled into the guide rail 5. During descending of the lifting body while the lubricating oil runs short in the guide rail 5, the sliders 41-43 are pulled and moved by excessive sliding resistance generated between the guide rail 5 and the sliders, so that the application members 41-43 are moved to the operation position against holding force generated by the holding structure.

    【課題】簡素な構成でガイドレールに対する過度な潤滑油の供給を防止すること。【解決手段】潤滑油を貯留し昇降体と一体で昇降するケース31と、ガイドレール5に対し離間した初期位置からガイドレール5に接触する作動位置に移動可能にケース31に保持された塗布部材41〜43と、ケース31内の潤滑油を毛細管現象で吸い上げて塗布部材41〜43に供給する吸上げ部材51,52等と、塗布部材41〜43と結合した状態でガイドレール5に接触して位置する摺動子41〜43と、昇降体が停止した状態、および、ガイドレール5における潤滑油が充足した状態において、塗布部材41〜43のそれぞれを初期位置に保持する保持構造とを備え、ガイドレール5における潤滑油が不足した状態での昇降体の下降中に、摺動子41〜43はガイドレール5との間に生じる過大な摺動抵抗により引き動かされることで、保持構造による保持力に抗して塗布部材41〜43を作動位置に移動させる。【選択図】図5
