Abstract: The present invention provides a rocker arm manufacturing method capable of improving the durability and excellent in productivity. In the method according to the present invention, an intermediate product 13 having both side walls 20 extended in a predetermined direction and arranged in parallel with each other and one end side connection wall 30 connecting lower ends of a longitudinal one end of both the side walls is obtained. Next, both side walls 20 formed at the one end of the intermediate product 13 are inwardly bent. Thereafter, ironing dies 60 are pressed down against outer surfaces of both the inclined side walls 20 from an upper side to a lower side to execute ironing of outer surface portions of both the side walls 20 to downwardly plastically fluidize the constituent material of both the side walls 20 to thereby form valve stem guide walls 35 at both sides of the one end side connection wall 30 in a downwardly protruded manner.

Abstract: A method for manufacturing a one-way clutch cage allows slits of the cage to be formed with a short punching distance, wherein the slits are narrow in width and the cage is less prone to deformation. In this method for manufacturing a one-way clutch cage, after slits 8, 10, 11, 12 have been formed, windows 17 are formed and then an outer annular part 18 is cut. Therefore, since the slits can be formed in a cylindrical member 2 that has not yet been subjected to the window formation process of the outer annular part cut-out process, and that is sufficiently strong, a radially diagonal punching operation can be performed to form the slits. During this radially diagonal punching operation, a boundary portion between a cylindrical portion 3 and an outer flange 5 is punched out from an inside of the cylindrical member toward an outside of the cylindrical member. Thus, the punching distance can be shortened, the punching die can be thinned in thickness and the slit width can be reduced, as compared with horizontal punching.

Abstract: A vulcanized sheet S1 having formed therein annular articles P1 is prepared at first, which sheet comprises thick external bridges (16) in a thin annular zone (14) and at regular angular intervals so that the bridges connect an external flash (13) to a body (15) of the sheet. A recess (22) is formed centrally of an inner waste (20) surrounded by each article. Then, a guide lug (34) is inserted in the recess to correctly position the article, before tearing by of a first punch (35) an inner breakable boundary (26) intervening between the article and the inner waste so as to remove the inner waste from the article. Next, a further guide lug (44) is inserted in a space from which the inner waste has been removed, a die having a bore (31a) of a diameter larger than the article supports the sheet, and finally a second punch (45) tears an outer breakable boundary (12) to separate the article from the sheet.
