[0004] In such an airbag system, the airbag system for the driver in the driver's seat is composed of an airbag module comprising an inflator that generates gas upon ignition of a detonator, an airbag that expands and deploys toward the driver in the driver's seat by the generated gas, a mounting plate on which the inflator is placed and which is fastened to the steering wheel with bolts, etc., and a horn plate installed on the upper part of the mounting plate, an impact sensor that generates an impact signal upon collision, and an electronic control module that ignites the detonator of the inflator according to the impact signal.

[0005] A shaft or tubular member made of a conductive material is pressed into the horn plate so that a signal generated from the horn is transmitted when the horn of the steering wheel is operated. Fastening holes are formed in the horn plate to allow the member to be pressed into the horn plate, and the member is pressed into the fastening holes so as to pass through them.

[0006] However, conventionally, the copper member of the shaft or tubular structure must be pressed into the aforementioned fastening holes to a certain depth, but since the worker must press it in manually, the copper member is pressed in at an uneven depth, resulting in defects. Furthermore, since a separate process must be performed to uniformly distribute the pressed copper member, there is a persistent problem of reduced productivity and process delay.

[0007] The aforementioned invention refers to background technology in the technical field to which the present invention belongs, and does not refer to prior art. Prior art literature

[0033] The above table body (20) is made of a panel structure.

[0034] The above table body (20) is made of metal or synthetic resin and is formed into a square panel structure.

[0035] Support legs can be further screwed and fixed to the bottom surface of the table body (20), and it is also possible to move it by attaching casters.

[0037] The guide support frame (30) is formed on the upper surface of the table body (20), and the horn plate (100) is placed on the upper surface.

[0038] The above guide support frame (30) is formed as a square frame structure, and its lower end is fixed by being screw-fastened or attached to the upper surface of the table body (20), and the horn plate (100) is placed on the upper part.

[0039] The above guide support frame (30) supports the bottom edge portion of the horn plate (100).

[0041] The above spacing panel body (40) is fitted into the guide support frame (30) and supports the lower part of the object (200) that is fastened to the horn plate (100).
