A switching device includes an operational knob including a first supporting portion including a first coupling portion, the operational knob being enabled to be swung around the first coupling portion as a rotational center, and a switch main body including a second supporting portion including a second coupling portion that rotatably supports the operational knob by being coupled with the first coupling portion. The first supporting portion or the second supporting portion is resiliently deformable when mounting the operational knob on switch main body. The first supporting portion or the second supporting portion further includes an interference lessening portion at a corner of an assembly terminating end side of the first coupling portion or the second coupling portion.

Mount for a switching device operation knob

A press-fit portion () of a press-fit pin () is constructed by cutting and outwardly pushing a band-like region (), which is placed in the vicinity of the widthwise center of a pin material, in one of orientations of the thickness direction in such a way as to project from peripheral regions () of the band-like region (). At that time, the thickness dimension (W) of the press-fit portion () is set to be equal to or less than that Wof a pin body ().
