According to the present invention, as is apparent from the above description of the embodiment, the output terminal is opposed to the pull-out force by the tapered portion, and the protrusion is fitted to the concave portion of the output terminal insertion hole to reduce the rotational force. Since it is fixed to the output terminal insertion hole in opposition, it exhibits strong durability against various external forces including vibration without fixing with the casting resin. For this reason, it is possible to prevent the lead wire wound around the lead wire terminal of the output terminal and soldered from being broken by stress due to vibration. Further, since the projection is provided on the large diameter portion of the output terminal, the output terminal can be easily inserted into the output terminal hole.
