種類が削減できてコスト安になる。Further, if the rib forming position can be changed by using the rib for preventing erroneous assembly of the housing as a movable rib, various kinds of housings in which the rib forming position is changed are prepared. Even if it is not necessary, it can be dealt with only by changing the formation position of the slit of the electronic circuit board, so that the type of housing can be reduced and the cost can be reduced.
