Description of the Related Art Conventionally, an operating element A such as a brake pedal or a transmission pedal of a vehicle is composed of a forked arm having two arms B and C integrally formed of steel as shown in FIG. One arm B is operated by a driver's toe, and the other C is directly connected to a connecting link D such as an operation wire or an operation rod, or a transmission shaft (not shown).

ので、大幅なコスト低下を得ることはできなかった。However, when the operating element is made by hot forging, an expensive die is required for forging the material, and the forged material does not become a product unless forged.
Since machining was required to finish the joints of the connecting links and the bearing holes, many steps were required for manufacturing, and the production cost could not be avoided. Further, since the forked arm formed by press molding is mainly made of a steel plate, the effect of reducing the manufacturing cost was recognized, but the appearance quality was low, and it was mainly applied only to inexpensive products. From a functional point of view, welding was performed at places where stress was concentrated, such as the connection between the main part and the operation pedal or operation lever, and the connection between the pipe inserted into the support shaft, so that normal welding was possible. The structure had to be higher in rigidity than that, and the number of welding steps increased, so that a significant cost reduction could not be obtained.

Are connected at a specific angle (phase) determined by the meshing of the brake pedal 10. Therefore, the brake pedal 10 is constituted by at least two arm members, and they are joined without welding. Also,
The angle at which the pedal arm 12 and the pulling arm 13 cross each other can be changed by changing the meshing position of the butting serrations 12d and 13e, and they are relatively easily different from the case where all of them are newly formed. It is possible to obtain the brake pedal 10 having the specifications. When the design is changed, it is also possible to obtain a brake pedal 10 having different specifications by changing one of the pedal arm 12 and the tension arm 13 and diverting the other. Further, the pedal arm 12, the operation unit 14, and the pull arm 13
And the ball rod 13c are integrally formed metallurgically and are formed by being bent by plastic working, so that the appearance is improved and the reduction in mechanical strength and the number of manufacturing steps due to welding are avoided. And can be manufactured at a low cost.

ある。FIG. 10 shows an embodiment in which the butt serrations 12d and 13e in the embodiment are stopped, and the inner surface of the through hole 12a is modified. Specifically, an internal gear 20 is formed, and its tip circle is slightly smaller than the coupling shaft 13a. A large-diameter annular hole 30 facing the outside of the pedal arm 12 is formed concentrically. The internal gear 20 and the annular hole 3
0 is formed simultaneously with plastic working of the through hole 12a. Thus, the connecting shaft 13a is connected to the through-hole 1 of the pedal arm 12.
After fitting into 2a, the end portion is pressed and enlarged to flow into the valley portion of the internal gear 20 and the annular hole 30 to be filled. Thus, the pedal arm 12 and the pull arm 13 are integrally connected. According to this modification, it is not necessary to previously provide a butt serration 13e on the side of the pulling arm 13 as in the above-mentioned modification, and the phase of the pedal arm 12 and the pulling arm 13 is determined by an assembling jig (not shown). The angle can be changed to an arbitrary angle by changing ()). Furthermore, the amount by which the distal end of the coupling shaft 13a protrudes to the outer surface of the pedal arm 12 in the assembled state can be minimized. In this example,
The irregular shape formed on the inner surface of the through-hole 12a is not limited to the internal gear 20, but it goes without saying that the coupling shaft 13a may be chamfered on two opposing surfaces to have an elliptical cross section.

Processing can be minimized. Therefore, improvement in mechanical strength and reduction in cost can be obtained together. According to the second aspect of the present invention, when one arm member and the other arm member are overlapped and joined together by plastic working, the phases of both can be accurately obtained. According to the third aspect of the present invention, since the angle formed by the two arm members can be changed by changing the engagement position of the butting serration of the both arm members, only the engagement position is changed, or one of the arm members is changed. A different operation pedal can be obtained simply by changing the design, and the degree of freedom in design increases. According to the fourth aspect of the invention, in addition to the effects described in the first aspect, the angle between the two arm members can be changed without changing the mold when changing the design, and the degree of freedom in design is increased. In addition, the outer surface of the pedal arm 12 can be formed relatively smoothly after the assembly is completed. And so on.
