Abstract
PURPOSE: To improve productivity by forming a hollow groove for winding of a brake band by pressing on the outside circumferential surface of a brake drum.
CONSTITUTION: A brake drum 17 and a collar 18 formed at one end on the outside circumference of the drum 17 are formed into one piece by pressing. Next, when a projecting part 19 is formed at the other end of the outside circumference of the drum 17 by ironing together the outside circumferential metal of the drum 17, the brake drum 17 having a hollow groove 21 for the purpose of winding a brake band 20 is made. Hence, the hollow groove is formed on the outside circumference of the drum 17 by pressing alone without cutting and without using any separate members and productivity is considerably improved.
