PROBLEM TO BE SOLVED: To provide a device for diagnosing a clearance of an elevator capable of estimating an adjustment time when an adjustment work of the clearance is required beforehand.SOLUTION: A clearance diagnosis part 11 provided on a device for diagnosing a clearance includes: a recording part 12 which records a measurement value measured by a clearance measurement device 10 for measuring the clearance between a counterweight 3 and a shock absorber 6 and operation information of a car 2 outputted from a controller 5 for controlling the travelling of the car 2; and an estimation part 13 which calculates a clearance estimation value in the future on the basis of the measurement value recorded by the recording part 12 and the operation information of the car 2, and estimates a clearance adjustment time E attaining to a prescribed judgement value D corresponding to an adjustment target value of the clearance with the calculated clearance estimation value.SELECTED DRAWING: Figure 2

    【課題】クリアランスの調整作業が必要となる調整時期を事前に予測することができるエレベータのクリアランス診断装置の提供。【解決手段】本発明に係るクリアランス診断装置に備えられるクリアランス診断部11は、釣り合い錘3と緩衝器6とのクリアランスを計測するクリアランス計測装置10で計測された計測値と、乗かご2の走行を制御する制御装置5から出力される乗かご2の運行情報とを記録する記録部12と、この記録部12で記録された前述の計測値と、乗かご2の運行情報とに基づいて、将来のクリアランス予測値を演算し、演算されたクリアランス予測値が、クリアランスの調整目標値に対応する所定の判定値Dに至るクリアランス調整時期Eを予測する予測部13とを含んでいる。【選択図】図2
