A wheel for driving a flexible handrail of an escalator or moving walk. The wheel has a power transmission element that can be turned about an axis of rotation and that has, on its circumference a contact surface through which an outwardly acting radial force can be exerted. The wheel also has two base sheaves that are arranged coaxially to the power transmission element. Each base sheave has a plurality of slits that are arranged in the outer edge area of the base sheave and extend toward the axis of rotation. The slits of one base sheave form, with the slits of the other base sheave, slit pairs. The wheel has a circumferential cover with an inside surface against which the contact surface of the power transmission element rests. A plurality of pins is arranged in the circumferential cover, each pin engaging a separate respective slit pair.
