PROBLEM TO BE SOLVED: To provide a gap adjustment jig of a proximity switch by which a gap formed between a shield plate and an inside wall of an aperture of the proximity switch into which the shield plate is entered can be easily adjusted.SOLUTION: In an escalator including a proximity switch 11 which outputs a signal for speed control, a gap adjustment jig of the proximity switch is provided to adjust gaps G1, G2 among a detector 10c of the shield plate 10, and inside walls 11b, 11c of the aperture 11a of the proximity switch 11. The gap adjustment jig of the proximity switch comprises: a self-holding part 20a of which shield plate 10 is made from ferromagnetic material to be fitted into the aperture 11a of the proximity switch 11 and presses the inside walls 11b, 11c of the aperture 11a while being fitted into the aperture 11a to prevent from falling from the aperture 11a; and first, and second gap setting parts 21, 22 arranged in the self-holding part 20a which have thickness dimensions according to the gaps G1, and G2 and are made of magnet.SELECTED DRAWING: Figure 6 |
