A motor shaft anti-rotation structure which is applied to secure a motor shaft to a carrier includes an anti-rotation sleeve and a screwing member. The anti-rotation sleeve includes a sleeve wall surrounding and defining an inner space, a pressing portion protruding radially and inward from the sleeve wall to separate the inner space into a motor shaft region and a screwing member region, a through hole penetrating the pressing portion and communicated with the motor shaft region and the screwing member region, and a restricting protrusion protruding outward from the sleeve wall and corresponding to an inserted hole of the carrier. The screwing member includes a threaded portion inserting in the through hole to screw into the motor shaft, and a head portion connected to the threaded portion and configured to press against the pressing portion. The head portion is configured to be received in the screwing member region.
