A lifting device of a cordless covering (100) includes a cord reel (40), a car (52), a driving module, a connecting cord (53), and a lifting cord (54). The cord reel (40) has a cone section, and is pivoted on a headrail (10) for free rotation. The car (52) is received in the headrail (10) for reciprocation. The driving module is received in the headrail (10) to drive the cord reel (40) to rotate in a predetermined direction. The connecting cord (53) has opposite ends connected to the car (52) and the cord reel (40), wherein the connecting cord (53) is reeled in and out of the cone section of the cord reel (40) when the cord reel (40) rotates in different directions. The lifting cord (54) runs around the car (52), and then extends out of the headrail (10) to be fastened to a bottom rail (20). The cord reel (40) and the driving module are helpful to precisely stop the bottom rail (20) at any desired position. |
