Since it is manufactured through 21, the amount of indentation in both directions can be reduced when cold-pressing is performed in the third step for obtaining the second intermediate material 20 and the fourth step for obtaining the third intermediate material 21. By making relative adjustments, the attachment position of the pulley portion 12 to the coil case portion 11 and the relative position of the pulley portion 12 to the coil case portion 11 can be arbitrarily changed. For example, the clutch portion 14 of the pulley portion 12 can be changed. It is also possible that the side end 12p (see FIG. 1) protrudes from the coil case bottom outer surface 14a (see FIG. 1) of the clutch portion 14.

する電磁クラッチのプーリ付ロータの製造方法。1. A coil case portion of an annular exciting coil composed of a clutch portion, an inner cylindrical portion, and an outer cylindrical portion, and a belt driving force of a driving source are input to transmit a rotational force to a driven shaft. In a method of manufacturing a rotor with a pulley for an electromagnetic clutch having a pulley portion, a hollow disc material formed of a disc having a hole in the center is press-formed to form an annular body having a U-shaped cross section, and the annular body A first step of making a plate thickness of the clutch portion and the inner cylindrical portion which are configured to be a predetermined thickness smaller than a plate thickness of the hollow disc material; and a step of the outer cylindrical portion configured by the annular body. By cold compressing from the opening end side of the coil case portion, the plate thickness of the outer cylindrical portion on the opening end side of the coil case portion is set to a predetermined plate thickness, and the following plate thickness on the clutch portion side is set. Before the second step of thickening The outer cylinder portion has a predetermined plate thickness on the clutch portion side by cold pressing from the clutch portion side, and the support portion of the pulley portion and the side surface of the lower surface of the pulley portion on the clutch portion side are formed. By the third step of performing and cold pressing from the opening side of the coil case portion, the length of the outer cylindrical portion is set to a predetermined length, and the support portion of the pulley portion and the lower surface of the pulley portion are An electromagnetic wave comprising: a fourth step of forming a side surface on the opening end side of the coil case portion; and finally, a fifth step of forming a plurality of pulley grooves by inserting a slit in the pulley portion. Manufacturing method of rotor with clutch pulley.
