Cam for press die

A pressing cam die includes a cam slide having a cam surface; a supporting device for supporting the cam slide onto an upper die such that the cam slide is movable in a downwardly inclined direction; a coil spring for urging the cam slide toward its initial position; and a cam driver having a cam surface which is slidably brought into surface contact with the cam surface of the cam slide. The supporting device has a base and a round guide bar which is attached to a front wall portion and a rear wall portion of the base. The coil spring is wound around the guide bar and is disposed concentrically with the guide bar.
