Abstract
A transverse fan includes a pair of end plates each having an annular shape, a plurality of blades annularly disposed between the end plates and a plurality of partition plates each having an annular shape and disposed at intermediate portions of the blades. Each of the partition plates has one side surface to which base ends of the blades are integrally secured to extend forward with a predetermined inclination and form a multi-blade impeller. A plurality of the multi-blade impeller are stacked axially so that each of the partition plates has another one side surface to which leading ends of the blades of adjacent multi-blade impeller are connected, and one of the end plate has one surface to which the leading ends of the blades of a leading end side one of the stacked multi-blade impellers are connected and another one of the end plates has one surface to which the base ends of the blades of a base end side one of the stacked multi-blade impellers is secured. The another one of the end plates is provided with a boss portion to which a rotation shaft for rotating the transverse fan is secured. Each of the multi-blade impellers is injection molded integrally in a mold and the multi-blade impeller is thereafter withdrawn from the mold while rotating the multi-blade impeller about a rotation axis thereof.
