PROBLEM TO BE SOLVED: To provide a handrail belt drive device of a passenger conveyor capable of sufficiently ensuring a driving force of a handrail belt and preventing a drive belt from falling off.SOLUTION: A handrail belt drive device comprises a drive roller around which an inner peripheral surface of a handrail belt is wound, and a pressing mechanism disposed along an outer peripheral surface of a winding part of the handrail belt, which is wound around the drive roller in a circular shape. The pressing mechanism includes: a pair of guide rollers provided at positions corresponding to the winding part of the handrail belt; a drive belt endlessly wound between the guide rollers and having a first tension region in contact with the winding part of the handrail belt and a second tension region facing the first tension region; and at least one intermediate roller in contact with an inner peripheral surface of the first tension region of the drive belt. An engaging part hindering movement of the drive belt along a width direction of the drive belt is provided at a contact part between at least either one of the guide roller and the intermediate roller and the drive belt.SELECTED DRAWING: Figure 2
【課題】手摺りベルトの駆動力を十分に確保できるとともに、駆動ベルトの脱落を防止できる乗客コンベアの手摺りベルト駆動装置を得ることにある。【解決手段】手摺りベルト駆動装置は、手摺りベルトの内周面が巻き掛けられた駆動ローラと、手摺りベルトのうち駆動ローラに円弧状に巻き掛けられた巻き掛け部の外周面に沿って配置された押圧機構と、を備えている。押圧機構は、手摺りベルトの巻き掛け部に対応する位置に設けられた一対のガイドローラと、ガイドローラの間に無端状に巻き掛けられ、手摺りベルトの巻き掛け部に接する第1の張り領域と、第1の張り領域と向かい合う第2の張り領域とを有する駆動ベルトと、駆動ベルトの第1の張り領域の内周面に接触する少なくとも一つの中間ローラと、を含む。ガイドローラおよび中間ローラの少なくともいずれか一方と駆動ベルトとの接触部に、駆動ベルトの幅方向に沿う駆動ベルトの移動を妨げる係合部が設けられている。【選択図】図2
