Further, burrs may be generated on the outer peripheral edge of the pressed portion after rolling depending on the shape thereof. In this case, smoothing is performed by performing a trimming process.

  As another embodiment of the pulling wheel and hook metal fitting of the present invention, the rolling device 21 described above is used, and as shown in FIG. 8A, the pulling wheel opening / closing operation member 3 is given as an example. By tilting and fixing the original part 23 of the member 3 and rolling as shown in FIG. 8B, a member in which the knob portion 9 is inclined in the closing direction of the opening / closing operation member 3 is formed. Specifically, as shown in FIGS. 9A to 9C, the knob portion 9 of the opening / closing operation member 3 is inclined from the vertical position P toward the closing side of the opening / closing operation member 3, and the inclination angle is 15 °. It is set to. When formed in this way, when the knob portion 9 is pressed and pulled with the finger F, the finger F is applied to the tip of the inclined knob portion 9 as shown in FIG. The opening / closing operation member 3 can be pulled. Further, as shown in FIG. 10B, when the opening / closing operation member 3 is pulled in the opening direction, the finger F is caught on the knob portion 9 and a light force is applied along the outer periphery of the annular member 1. Can be drawn. Further, the inclination angle of the knob portion 9 is set to 15 ° in the present embodiment, but if the angle is within a range of 5 ° to 25 ° from the vertical position P, the pressed portion of the knob portion 9 at the time of operation. The finger F is easily applied to 9b, and the opening / closing operation member 3 can be pulled with a light force. Further, if the inclination angle of the knob portion 9 is an acute angle than 5 °, the tip of the knob portion 9 faces away from the finger F as shown in FIGS. When pressed, the tip of the knob portion 9 must be pressed with a strong force, which causes a pain of piercing when the opening / closing operation member 3 is operated. Further, as shown in FIGS. 12A and 12B, when the inclination angle of the knob portion 9 is an obtuse angle than 15 ° (in the embodiment, the inclination angle is 35 ° from the vertical position P in the opening direction of the opening / closing operation member 3). ) When the knob portion 9 is pressed by the belly portion of the finger F, the finger F is not easily caught by the pressed portion 9b, so that the pressing force of the finger F is not transmitted well to the pressed portion 9b of the knob portion 9. There is a disadvantage that it becomes difficult to press the pressed portion 9b with the finger F.
