のユニットの手すり駆動機構から取り外し可能である。As described above, according to the invention according to claim 1, a plurality of sets of drive wheels arranged vertically on a base plate fixed to a truss and axially supported by the base plate, and driven by the base plate. Equipped with driven wheels that are placed opposite to the wheels and are pivotally supported by a plurality of sets of support frames whose base ends are supported by spindles and other ends are supported by coil springs, and which move the handrail against the drive wheels by the restoring force of the coil springs. in escalator handrail drive mechanism, before
The support frame is provided with a shaft support portion projecting on the base end side and on the other side.
It has a convex shape with a spring receiving part protruding from it,
One side of the driven shaft that supports the driving wheel is provided through the bottom of the support frame.
By supporting the base end side of each set of support frames on the base plate with a common support shaft, the number of support shafts that support the support frame to the base plate is reduced, and the handrails for moving the driven wheels by the coil springs are reduced. Since the variation of the pressing force on the
It is possible to obtain a handrail drive mechanism for an escalator, which enables easy inspection work. Also, bearing replacement work
Removes only the driven shaft from the support frame,
It is removable from the handrail drive mechanism of the unit .

スカレータの手すり駆動機構を得ることができる。Further, according to the invention particularly corresponding to claim 2 , since the fluorocarbon resin coating is formed on the outer periphery of the drive wheel, dust adhering to the outer periphery of the drive wheel is reduced by the fluorocarbon resin coating. It is possible to obtain a handrail drive mechanism for an escalator, which can prevent the moving handrail from being soiled.
