<p>PURPOSE:To prevent the shaking of a dust collection electrode plate in an electrode unit and to eliminate the generation of spark discharge, by arranging an electrode holding member, which can be engaged with or disengaged from each dust collector electrode plate, to the electrode unit. CONSTITUTION:In such a state that dust collection electrode plates 69, 70 are received in an electrode unit 27, an electrode holding member 78 is arranged to the holding position engaged with each of the dust collection electrode plates 69, 70 and, by this mechanism, the dust collection electrode plates 69, 70 are held at the definite position to a drive electrode plate 61 in an unmovable state. In cleaning or replacing the dust collection electrode plates 69, 70, if the electrode holding member 78 is arranged at a release position, the holding state of the dust collection electrode plates 69, 70 is released and, therefore, the dust collection electrode plates 69, 70 can be easily taken out from the electrode unit 72 in this state.</p> |
