Wheel (10) for driving a flexible handrail of an escalator or moving walk. The wheel (10) has a power transmission element (40) that can be turned about an axis of rotation and that has on its circumference a contact surface (42) through which an outwardly acting radial force can be exerted. In addition, the wheel (10) has two base sheaves (20, 21) that are arranged coaxially to the power transmission element (40). Each base sheave (20, 21) has a plurality of slits (26) which are arranged in the outer edge area of the base sheave (20, 21) and directed toward the axis of rotation. The slits (26) of one base sheave (20) form with the slits (26) of the other base sheave (21) slit pairs (27). The wheel (10) has a circumferential cover (60) against at least part of whose inside surface (64) the contact surface (42) of the power transmission element (40) rests. A plurality of pins (80) is arranged in the circumferential cover (60), one pin (80) engaging in each respective slit pair (27).
