A cordless roller shade includes a head unit (1), a shading face (2) mounted on the head unit, an elastic dynamic device (13) mounted on the head unit, and a bottom unit (3) mounted on the shading face. The elastic dynamic 5 device includes a spring (133) having a thickness ranged between 0.1mm and 0.2mm. The bottom unit includes at least one balance member (33) having a determined weight ranged between 0.1kg and 1.2kg, and the shading face and the bottom unit have a total weight ranged between 1kg and 5kg, to balance the torque of the spring of the elastic dynamic device, so that the shading face is 10 moved by the bottom unit to a determined position and is located at the determined position. (FIG. 1)
