Abstract

PURPOSE: To enable a duct fan to be fixed at a plural points by forming the outer circumference face of supporting rods installed to the outer circumference face of the duct into nonround, and making nonround holes in a supporting body into which the nonround parts of the rods are securely set.
CONSTITUTION: On the outer circumference face of a duct 1, supporting rods 11 and 12 are installed facing each other and putting a shaft 9 of an impeller 2 between them, with their tips 10 pointed outward. The rod 11 consists of a bolt 14 which has a regularly hexagonal head 13 and is secured to the duct 1 by welding. Outside the duct 1, a supporting body 4 having regularly hexagonal holes 16 and 17 into which the heads 13 of the supporting rods 11 and 12 are set, is installed. Thus, the duct can be at a plural points so as to avoid moving due to its vibration or tare by screwing or loosening a nut 20 on a bolt 14 so that the head 13 and the hole 16 are joined with or released from each other.
