A bearing structure includes a bearing having a shaft hole formed by an inner wall of the bearing. The outer periphery of the bearing has multiple outer walls and multiple deformable zones. The multiple outer walls are located at the axial direction of the same radius circumference with the center of the shaft hole as a center of circle thereof. Each of the multiple deformable zones is provided on the outer periphery of the bearing between any two outer walls, and is deformable to absorb an outer stress. When the bearing is closely mounted in a shaft tube during a punching process, the multiple deformable zones of the outer face of the bearing may absorb the outer stress, thereby preventing the inner wall of the bearing from being deformed.
