TENSION ADJUSTMENT DEVICE AND PASSENGER CONVEYOR

To provide a moving handrail tension adjustment device capable of maintaining optimal pressing pressure for a long time and preventing damaging when a sudden shock force is applied during driving, and a passenger conveyor.SOLUTION: A tension adjustment device 7 disposed in an endless moving handrail 3 provided to a passenger conveyor for conveying a passenger so as to adjust the tension of the moving handrail 3 comprises: a roller 13 that abuts against the moving handrail 3; a tension application unit 15 that presses the roller 13 by a prescribed pressing force to apply tension to the moving handrail; a roller support member 17 that supports the roller 13 so as to be displaced in a pressing direction and its opposite direction of the tension application unit 15; and displacement restraining means 20 that restrains displacement of the roller 13. The displacement restraining means 20 permits the roller 13 to move in the pressing direction and its opposite direction, and restraints the displacement of the roller 13 in the pressing direction and its opposite direction when the roller 13 receives a reactive force exceeding the pressing force applied by the tension application unit 15.SELECTED DRAWING: Figure 2 【課題】最適な押圧力を長期間維持し続けることができ且つ駆動中に急激な衝撃力が作用したときに損傷を防止できる移動手すりの張力調整装置及び乗客コンベアを提供する。【解決手段】乗客を搬送する乗客コンベアに設けた無端状の移動手すり３に配置され、移動手すり３の張力を調整する張力調整装置７であって、移動手すり３に当接するローラ１３と、ローラ１３を所定の押圧力で押圧して移動手すりに張力を付与する張力付与部１５と、ローラ１３を張力付与部１５の押圧方向及びその反対方向に変位自在に支持するローラ支持部材１７と、ローラ１３の変位を拘束する変位拘束手段２０を備え、変位拘束手段２０は、ローラ１３が押圧方向及びその反対方向に移動するのを許容し、ローラ１３が張力付与部１５で付与する押圧力を超える反力を受けたときにローラ１３の押圧方向と反対側への変位を拘束する。【選択図】図２
