| 摘要 | PURPOSE: To reduce manhours for assembling a trip cross bar to a side plate. CONSTITUTION: An L-shaped bending portion 9a is formed in a supporting pin 9 inserted between a supporting fitting 3 of a trip cross bar and a side plate 6 of a switch mechanism for rotatably supporting the trip cross bar 1. The L-shaped bending portion 9a abuts against a stopper surface 13 of an insulating bar 2, thereby preventing the supporting pin 9 from being drawn out. Consequently, it is possible to make unnecessary additional machining, which has been conventionally required in order to plastically deform a part of the insulative bar 2 in the vertical direction to prevent drawing-out, after insertion of the supporting pin 9, and a facility for the additional machining.
