作に対する応答性が劣る懸念があった。By the way, in the conventional mounting structure of the rotary operation type electric component described above, the positioning hole 6 of the ear 1a and the positioning hole 7 of the ear 1b are provided on the housing 1 side, and the bearing Since the bush 9 is insert-molded in the housing 1, when the housing 1 and the bush 9 are insert-molded with a synthetic resin, the bearing bush 9 in the center portion is positioned with respect to the two positioning holes 6, 9 serving as an attachment reference.
However, there has been a problem that it is easy to shift from a predetermined position. And
If the bearing bush 9 is displaced from the predetermined position, the positional relationship of the second rotating body 8 with respect to the first rotating body 5 is lost, so that the depression amount of the accelerator pedal connected to the first rotating body 5 is reduced. It becomes difficult to accurately detect the corresponding signal from the rotary operation type electric component, and there is a concern that the response to the depression operation of the accelerator pedal is deteriorated.
