    摘要: A method for producing a holder in which sagging is suppressed in a bent part to be formed into a flange portion, without using bulge forming and a split mold that restrains the inside of a working target article; and a holder. An upper punch presses and bends one end portion of a working target article inward, whereby a flange portion is formed in the one end portion. A smaller-diameter portion of the working target article is restrained from the inside and outside by a lower punch and split mold portions. Then, a peripheral surface portion of a convex portion of the upper punch receives the end portion of the working target article and applies an outward pressure to the end portion. A bent part is pushed toward a larger-diameter portion restraining part of a split die, so that sagging is prevented from occurring in the bent part.

    摘要: Disclosed is a method for manufacturing a transmission bearing retainer. The method includes a step of forming a bolt hole at the bearing retainer, wherein the bolt is inserted into the bolt hole. The step of forming the bolt hole includes: a step of forming a holt base hole of the bolt hole through piercing of a press working method; a step of forming an expanded hole through a first cold forging of the press working method, wherein a bolt head of the bolt being in contact with the expanded hole; and a step of forming anti-rotation grooves on a surface of the expanded hole through a second cold forging.

    摘要: A radial cage in which roll forming is carried out in such a manner that straight side sections of all axial crossbars continue to have at least approximately a material thickness of a starting material for the radial cage, while side rings of the radial cage and axial center sections of the axial crossbars are implemented by rolling down during roll forming to each have material thicknesses that are smaller than the material thickness of the straight side sections and that reduce their centrifugal mass.
