支持する部材として利用されている。As shown in Fig. 1, the parallel bimetal has a structure in which the metal body M on the high m1iI side and the metal body B on the low expansion side are arranged in the radial direction, and the edges of both metal bodies M10 in the length direction O side are joined to each other. and is displaced in the radial direction (due to temperature changes). The .zeta.O-parallel and cylindrical lenses are used, for example, as members for elastically supporting a shadow mask on a face panel in a 2-TeleC receiver.

高める上で限界があった。Therefore, the metal body of the conventional 11 m bimetal high-speed metal body and each metal body number on the low expansion side are joined by arc welding, electric resistance welding, f2 Zuma welding, etc. However, when the side edges of the alloy metal bodies M and B are joined by welding, a welded part C with a structure different from that of the metal bodies M and B is interposed between the side edges, and the metal bodies M and B are integrated. Because it is not joined with a normal structure, it is average! [I/Medium] The mechanical strength of the welded part C to join the metal body 1 and the sides is low against the force generated when the metal 1 moves, and the metal body 1 often separates. And conventional! Since the contact bimetallic method involves joining metal bodies arranged in the width direction by simply welding narrow points along each side edge, there is a limit to the ability to increase the joining strength of the metal bodies.

＊Because the facing body Kil is in contact, it is not necessary and only the edges are needed. 1. Next, hot rolling is applied to the combined material 4.5, and piezoelectricity is applied to the material 4.1 by passing it through the rolling holes. ] As shown in FIG. 5, a wide strip of material is formed by combining materials 4.5. In this hot rolling process, the material 4. l

& are crimped together. After hot rolling, cold rolling is performed to form the strip material into a predetermined size. Then, the center part of this wide strip material (the center part of materials 4 and 5) is cut along the length direction with a cutter, and divided into two narrow strip materials. It has the form of a plurality of parallel bimetal wires lined up in a row, and is cut into a metal body 1. It is possible to obtain a plurality of parallel bimetallic molecules consisting of 1. Note that the joint between the groove bottom 6 of the material 4 and the material 5 becomes the joint between the - portion 3 of the metal body 1 and the metal body 2.

In addition to the basic structure of tLiI/f metal, in which metal body 1 and metal body 2 are arranged in the width direction and their longitudinal side edges are joined,
Furthermore, a part of one metal body 1 overlaps the side surface of the other metal body 2 and is joined, and this joint is crimped when rolling the materials 4 and 5 in the bimetal manufacturing process. It is something. The joint portion between the part 1 of the metal body 1 and the metal body 1 has a structure similar to that in the rolled state.
The two structures directly diffuse into each other and are tightly pressed together, so the joint strength is high. Moreover, the joint part 3 between part 3 of the metal body 1 and the metal body 2 has a much larger area than the joint part at the side edge of the metal body 1. Since they fit together and are crimped together,
The multi-joint strength is increased. In other words, while maintaining the basic structure of the parallel bimetal, part S of the metal body 1 and the metal body 2 are joined by pressure bonding, so compared to the conventional parallel bimetal. The bond between the metal bodies is surprisingly strong and durable. In addition, the joining part between the part I of the metal body 1 and the metal body 2, and the material 4.5 for each metal body are combined and rolled using a conventional rolling process. Since it is crimped, no special process is required and processing complexity can be avoided.

Because of this, the metal bodies are bonded together with great strength and have excellent durability. Then, when manufacturing bimetal, a part of one metal body is crimped and joined to the other metal body using the pressing process, which is conventionally used to straighten the material for the whole horse body. Therefore, when two metal bodies are bonded together by pressure bonding, the strength of the seven OII joints is large, and there is no need to provide a special hole to bond two metal bodies together (easily KI
