A reeling device for a window covering comprises a plurality of guiding wheels 2 provided in a line arrangement and a number of S-shaped resilient coils 23. Two adjacent guiding wheels 2 are engaged with each other by peripheral teeth 21 formed thereon. One of the two adjacent guiding wheels 2 includes one cord 22 wound thereon opposite to another cord 22 wound on another of the two adjacent guiding wheels 2. The two adjacent guiding wheels 2 have an S-shaped resilient coil 23 secured between them. The S-shaped resilient coil 23 provides a resilient force to operate the cords 22 simultaneously, and to balance the weight of a curtain. The cords may be longitudinally attached onto the curtain and control the expansion or retraction thereof. |
