发明名称	ELEVATION OPERATING APPARATUS FOR BLIND
摘要	A lifting mechanism for a blind is provided to prevent counter-rotation of the blind roll completely because the rotary shaft is mounted to the forward direction bearing and the counter-rotating of the inside revolution body is again prevented. A lifting mechanism for a blind comprises a ball chain rotary gear(150), a rotary shaft(110) and an internal rotational member(120). The lifting mechanism comprises a fastening member(130) and an inner casing(140). In the ball chain rotary gear, a hollow is formed. In the outer circumference of the ball chain rotary gear, a groove(151) corresponding to the ball chain is formed. The rotary shaft is inserted in the hollow of the ball chain rotary gear. In the outer circumference of the rotation axis, a screw(111) is formed in the prescribed section and the rotary shaft(170) is inserted. The internal rotational member is corresponded to the screw of the rotary shaft.
