For example, a pair of bridging members 3 and 4 made of a sheet metal are spanned between the pair of side plates 2 of the frame 1, and bent portions 5a for attaching side plates provided at both ends of the bridging members 3 and 4, 5b is attached to the side plate 2. These bridging members 3 and 4 are attached for the purpose of reinforcing the frame 1, but normally, for example, a pair of bent parts 6a and 6b for attaching parts are provided on the bridging members 3 and 4, respectively. These bent parts 6
Equipment parts 7 such as printed circuit boards are mounted on a and 6b. Such bridging members 3, 4
Possible examples include the following:

以上のようなことを勘案すれば明らかなように、
本例の如き架橋部材３，４はどのような場合でも
利用できるとは限らないという問題点がある。Comparative Example 1 Using bridging members 3 and 4 of the same shape manufactured by a common mold, these bridging members 3 and 4 were oriented in opposite directions (point symmetrical) to each other as shown in FIGS. 1 and 2. Attach it to the side plate 2 of the frame 1 so that the In this case, although it is possible to reduce the cost of the chassis because the mold can be shared, the bent parts 6a and 6b for attaching parts are arranged at staggered positions without facing each other. So,
It becomes difficult to install equipment parts such as printed circuit boards. Therefore, in order to eliminate this inconvenience, if the bent parts 6a and 6b for attaching parts are provided at predetermined positions as shown by chain lines in FIG. 2, these bent parts 5 and 6 can be arranged opposite to each other. However,
In this case, the mounting position of the device component 7 is limited to the central portion of the bridge members 3 and 4 in the longitudinal direction.
For this reason, the equipment components 7 cannot be placed near both ends of the bridge members 3 and 4 in the longitudinal direction, and the design of the equipment is severely restricted.
Considering the above, it is clear that
There is a problem in that the bridging members 3 and 4 as in this example cannot be used in all cases.

高くなるという製作上の大きな問題点がある。Comparative Example 2 As shown in Fig. 3, a pair of bridging members 3 and 4 are bent so as to have mirror symmetry (line symmetry), and the bridging members are made with the bent parts 6a and 6b for attaching parts facing each other. 3 and 4 are attached to the side plate 2 of the frame body 1. In this case, the device parts are bent at the bent portions 6a, 6.
Although it is very convenient for mounting on the mold, it has the disadvantage that it is difficult to share the same mold because the punching burrs and the bending directions are opposite. That is, the bridging members 3, 4
When manufacturing, the punching process can be performed using a common mold, but the bending process for the side plate attachment bending parts 5a, 5b and the parts attachment bending parts 6a, 6b can be performed using separate molds. must be done. Therefore, there is a major manufacturing problem in that the manufacturing cost of the bridge members 3 and 4 increases.

く抑えることが可能である。 As described above, the present invention provides the first and second bridging members, which are constructed in such a manner that only the bending directions of the bent portions for attaching parts are opposite to each other, and the other shapes are identical to each other, between both side plates of the frame body. The first and second parts mounting bent parts are arranged to face each other on the same plane. Therefore, according to the chassis of the present invention, the frame can be reinforced by the first and second bridging members, and equipment parts such as printed circuit boards can be attached to the bent parts for mounting parts of the first and second bridging members. It can be installed very easily and the device structure can be designed with a very high degree of freedom. Moreover, since the only difference between the first and second bridging members is the bending direction of the bent part for attaching parts, the punching and bending processes other than this bending process can be performed using a common mold. This makes it possible to reduce the manufacturing cost of the bridge member and thus the chassis.
