Abstract

PROBLEM TO BE SOLVED: To facilitate abnormality determination based on the fact that a scale is raised when a positional relationship between an inductor and a plate is other than a managed value during car lowering by combining scales for measuring the gap dimension of each direction between the inductor and the plate and attaching these freely rotatably to the inductor. SOLUTION: For inspecting whether a gap dimension between the inductor 3 and the plate 4 of a landing device is within a proper range or not, first the center of an inspection jig is decided by a reference member 12 and then a base 11 is adsorbed on an attaching member 2. Then, vertical scales 14 and 15 and a horizontal scale 17 are fixed according the managed values of the inductor 3 and the plate 4 and each gap dimension is measured by the scales 14, 15 and 17. Then, an elevator is run for inspection, but at this time if the measured gap dimension does not match the managed value, the plate 4 comes into contact to raise the scale assembly. Thus, the failure of a gap dimension between the inductor 3 and the plate 4 is easily determined and set to the managed value by using scales 14a, 15a and 17a on the spot.
