A car cover, include a top piece and at least two-section side pieces. The two-section side pieces can be fabricated from side pieces and inclined pieces, edges of which are designed with non-straight convex arc line cut edges, and horizontally protruding regions are formed after joining the edges. The two-section side pieces can also be fabricated from front side pieces and rear side pieces, edges of which are designed with non-straight convex arc line cut edges, and vertically protruding regions are formed after joining the edges. Space within the outward expanding, curved protruding regions is used to contain rear-view mirrors of the car body when covering the car body with the car cover, thereby achieving a structure that is easy to manufacture and reduces manufacturing cost. Moreover, the car cover has universal suitability for many different car models and provides the convenience of covering and uncovering.
