A fan frame includes a body and a fan wire fixed on the body. The body is provided with a fixing spring plate which forms a free end. A fixing groove, through which the fan wire passes, is formed between the fixing spring plate and the outer surface of the body. The outer surface of the body protrudes outward to form at least one stop dog. The top end of the stop dog extends in the side direction and exceeds the free end of the fixing spring plate. The stop dog and the fixing spring plate form a space to contain the fan wire in the side direction. A guidance surface is gradually formed from the bottom end to the top end of the stop dog.
