PASSENGER CONVEYOR DRIVING MECHANISM, PASSENGER CONVEYOR, AND BELT MEMBER ADJUSTMENT METHOD IN PASSENGER CONVEYOR DRIVING MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a passenger conveyor driving mechanism which enables easy adjustment work of a tensile force of a belt member, and to provide a passenger conveyor and a belt member adjustment method in the passenger conveyor driving mechanism.SOLUTION: A driving mechanism 10 includes an electric motor body 31, a driving pulley 32, a reduction gear body 41, a driven pulley 48, a transmission sprocket 47, a belt member 23, an adjustment member 24, and a hook member 28. The hook member 28 is provided at a back end part opposite to an end part of the electric motor body 31, at which the driving pulley 32 is provided, and is engaged with a flange part 44 in the reduction gear body 41. The hook member 28 restricts movement in a direction which floats from a placement surface part 41a in the electric motor body 31.SELECTED DRAWING: Figure 4
