PURPOSE: A rear bump of a trailer is provided to improve the fuel efficiency of a trailer by minimizing an area where air, occurred in the rear of the trailer, swirls. CONSTITUTION: A rear bump(1) of a trailer comprises an attachment surface(2), a front end inclined surface(3), a rear end inclined surface(4), a middle horizontal surface(5), and a hinge receiving groove(7). The attachment surface is adhered to the top and side surfaces of a trailer. The front end inclined surface is gently protruded toward the rear of the trailer. The rear end inclined surface is steeply protruded toward the front of the trailer. The middle horizontal surface is formed between the front and rear end inclined surfaces and horizontally connects the top ends of the front and rear end inclined surfaces. The hinge receiving groove accepts hinges of a door installed in the rear of the trailer.
