Abstract
A cord retractor for a window covering comprises a housing and a driving wheel, a reeling wheel, a spring, a friction member and a unidirectional transmission mechanism. The driving wheel and the reeling wheel can rotate with each other. The spring is coupled with the driving wheel and is wound on or unwound from the driving wheel according to a rotating direction of the driving wheel. The friction member is in a closed loop shape and surrounding a shaft of the housing. The unidirectional transmission mechanism is coupled with the friction member and the reeling wheel, and operated in different operation modes according to a rotating direction of the reeling wheel, by which the friction member provides constant resistance to the rotation of the reeling wheel when the reeling wheel rotates in a first direction, and stops providing resistance when the reeling wheel rotates in a second direction.
