１の開口端面に当接する当接面１２を４１している。Therefore, in the pulley base material 3 clamped by the clamper 9, a gap IO is generated between the inner circumferential surface of the cylindrical portion l and the outer circumferential surface of the cylindrical protrusion 5 of the clamper 9, and an opening L1 of the cylindrical portion l is generated. The inner end 7 is clamped in a state in which it is in contact with an abutment part 8 provided at the base of the cylindrical protrusion 5. The outer periphery of the support abutment surface 6 at the tip of the cylindrical protrusion 5 of the clamper 9 is chamfered, so that when the support abutment surface 6 is brought into contact with the support 2 of the pulley base material 3, the support A gap 11 is created between the portion 2 and the outer periphery of the support portion abutting surface 6. Further, the clamper 9 has a contact surface 12 (41) that comes into contact with the open end surface of the cylindrical portion 1 of the pulley base material 3.

As a result, the portion 14 is crushed and escapes into the gap 11, the cylindrical portion 1 is further press-fitted into the gap 10, and the open end of the cylindrical portion 1 is prevented from being press-fitted into the gap by the connecting portion 8. 111 grooves 15 of the roll die 13 are formed on the outer peripheral surface of the cylindrical portion 1 leaving both open ends (FIG. 4). This becomes the hanging part 16, and this cylindrical part 1 is opened on both sides [■ To prevent belt from coming off on the end side/
The flanged portion 17 of 7'l is now formed, and a pulley is completed in which flanged portions are formed on both sides of the belt hanging portion to prevent the belt from coming off.
