PROBLEM TO BE SOLVED: To further facilitate measurement of a ratchet gap, which is a gap dimension between an apical surface of a tooth part of a ratchet wheel and a meshing surface of a claw part of a ratchet pole, which face each other, in an escalator.SOLUTION: A ratchet gap inspection support jig 68 of an escalator including a ratchet wheel 44 integrally rotating with a drive spindle of the escalator and having a plurality of tooth parts on an outer periphery thereof, and a ratchet pole 48 having a claw part 49 meshing with the tooth part 46 of the ratchet wheel 44 when a drive chain is disconnected includes a wheel side jig 70 and a pole side jig 80. The wheel side jig 70 has an attachment part 72 detachably attached to the ratchet wheel 44 by a magnetic force, and a measure abutment part 76 fixed to the attachment part 72 at a right angle and extending from a tip position of the tooth part 46 of the ratchet wheel 44 beyond a width dimension of the ratchet pole 48.SELECTED DRAWING: Figure 3

    【課題】エスカレータにおいて、ラチェットホイールの歯部の先端面と、ラチェットポールの爪部の噛合面との間の互いに向かい合う隙間寸法であるラチェット隙間の測定をより容易とすることである。【解決手段】エスカレータの駆動主軸と一体に回転し外周に複数の歯部を有するラチェットホイール44と、駆動チェーンが切断したときにラチェットホイール44の歯部46と噛み合う爪部49を有するラチェットポール48とを含むエスカレータのラチェット隙間点検支援治具68は、ホイール側治具70とポール側治具80とを含む。ホイール側治具70は ラチェットホイール44に磁力によって着脱自在に取付けられた取付部72と、取付部72に直角の角度で固定されラチェットホイール44の歯部46の先端位置からラチェットポール48の幅寸法を越えて延伸する物差し突当部76とを有する。【選択図】図3
