Abstract (en)
To provide a forming apparatus adapted to punch the outer periphery of the cylindrical portion of a bottomed cylindrical yoke that constitutes a flywheel to form a plurality of triggering projections without damaging the complete roundness of the yoke and with high workability. A triggering projection forming apparatus 7 is arranged in such a manner as to comprise: an inner guide body 10 to be butted against the inner periphery of the cylindrical portion 2a of a yoke; a projection forming punch 11 provided in the inner guide body 10 retractably in the punching direction; and an outer guide body 20 adapted to butt an abutting surface 20a with a receiving groove 20b for receiving the punch 11 formed therein against the outer periphery of the cylindrical portion 2a of the yoke to be pressurized, while the inner guide body 10 is connected with an auxiliary guide body 12 extending outside the cylindrical portion of the yoke 2, the auxiliary guide body 12 provided outside the cylindrical portion of the yoke 2 being adapted to receive the punching force of the outer guide body 20.
