Amended 1984. 3.30 The scope of claims for utility model registration shall be amended as follows. O Utility Model Registration Scope of Claims (1) At the opening end of the ventilation opening on the side where the fan is located of the cylindrical ventilation fan main body in which a fan and a driving motor for the fan are installed, - inside the ventilation opening; a first bell mouth part that extends in the direction of ventilation that is blown out from the ventilation port, a second bell mouth part that spreads in the direction of ventilation that is sucked in from the ventilation port, and a second bell mouth part that extends from the periphery of the first bell mouth part to the ventilation port opening. A ring-shaped first air passage member formed by integrally molding a ring part that extends apart from the plane into a conical shape by expanding the force, and the first air passage member at a position facing the ventilation opening are connected to the first air passage member. A ventilation fan characterized in that a second air passage member having approximately the same outer diameter as the first air passage member is provided substantially parallel to the passage member at a predetermined interval. (2) The ventilation fan according to claim 1, wherein the fan is positioned so as to partially protrude outward from the expansion start position of the first bell mouth portion. Ventilation fan.

Claims

[Scope of utility model registration request]

(1) A cylindrical ventilation fan body in which a fan and a motor for driving the fan are disposed inside the ventilation opening end of the ventilation opening on the side where the fan is located; a first bell mouth part that expands in the direction of ventilation to be sucked in from the ventilation port; a second bell mouth part that spreads in the direction of ventilation sucked in from the ventilation port; A ring-shaped first air path member formed by integrally molding a ring portion projecting into a planar shape is coupled to the first air path member at a position facing the ventilation opening through a predetermined interval from the first air path member. A ventilation fan characterized in that a second air passage member having approximately the same outer diameter as the first air passage member is provided substantially parallel to the first air passage member.

(2) The ventilation fan according to claim 1, wherein the fan is positioned so as to partially protrude outward from the opening end surface of the first bell mouth portion.
