Abstract

PURPOSE:To assure a dynamic blance without disturbing a flow of fluid, by properly seaping off a circular protrusion which is previously configured on the outer boundary of the outside wall of a side plate and a main plate. CONSTITUTION:Circular protrusions 21b and 22b are scraped off at the required positions as much as necessary in order to establish its proper position for assuring a dynamic balance - the former exists between the wall connected to a vane 23 of a main plate 21 of a fan and the outer boundary of an outside wall of the opposite side while the latter between the connected wall of a vane 23 of a side plate 22 and the outer boundary of the outside wall of the opposite side.
