Abstract

PURPOSE: To prevent the damage due to shaving of the push button lever, by pressing the corner edge of the protuberance of the metallic locking lever to make slide contact with the plastic push buttom lever, into a round shape.
CONSTITUTION: At press work for the sheet-metal locking lever 9 of the push- button device, a cavity 15 possessing round surface is formed at the part to form the locking protuberance 9b, using the punch 13. Next, the deepest part 15' of the cavity 15 is cut off with the punch 16. Hereby, the large rounded surface 14 is formed at the corner edge of the locking protuberance 9b of the sheet-metal locking lever 9 to make slide contact with the plastic push button lever 2.
