Abstract: A support structure of a multi-segmented blower for an air conditioner, which is modified from an inventor's prior art, blower assembly with multi segmented support arrangement for split air conditioner, rearrange and design the posts on a base of air conditioner, which set a trough and a pressure plate on a post to stand and fix a bearing, and an alternative post with bearing hole to embed a bearing for bearing a multi-segmented blower. A multi-segmented blower is a unit of at least two segments with bearings set on a shaft of blower, or at least two separated segments of the blower which can join each other with bearings for assembly together. Therefore, the present art can reduce assembly time and costs, and, in the same time, improve the durability of the blower, for lasting the using time and lowing down the possibility of a noise of a vibration, which is caused by the loosing of the bearing from the post of the base.
