An inexpensive pulley assembly is disclosed which accommodates a number of driving belts. The pulley includes a hub and a number of sheet metal members. These sheet metal members includes bases for attachment to the hub, inner flanges, sleeves flaring axially away from the inner flanges, and outer flanges. When the sheet metal members are assembled on the hub in an appropriately aligned and opposed array, the opposed, facing flanges form the belt-accommodating pulley assembly. The sheet metal members are rigidly attached to the hub by brazing and staking.
