Abstract
An arrangement for coupling a rotary member such as a pulley of V-belt or flat belt to a rotary shaft. A boss is mounted on the rotary shaft so that the rotary shaft will have its one end protruding from the boss. The protruding end is passed through a center hole in the rotary member. A nut is tightened on the end of the rotary shaft protruding from the center hole to tighten the rotary member and the boss and thus couple them together. A plurality of projections are formed on one of the rotary member and the boss and a plurality of cutouts or holes are provided in the other. The projections are inserted in the cutouts or holes to couple the rotary member and the boss together.
