Claims

[Scope of utility model registration request]

(1) At the opening end of the air outlet of a cylindrical ventilation fan body in which a fan and a motor for driving the fan are installed, there is a bell mouth part formed inside the air outlet and extending in the air outlet direction, and the bell mouth part that extends in the air outlet direction. A ring-shaped first air path member consisting of a ring portion extending from the periphery of the mouth portion substantially parallel to the opening surface is coupled to the first air path member at a position facing the air outlet at a predetermined distance from the first air path member. A second air path member having substantially the same outer diameter as the first air path member is provided substantially parallel to the first air path member, and the first air path member is provided with:
A ventilation fan, characterized in that a fixing piece to the mounting portion of the ventilation fan main body and a mounting piece of the second air path member are integrally cut and formed.

(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 bell mouth portion.
