<p>The present invention provides a ceiling-mounted air blowing device capable of reducing a number of parts and improving productivity and assemblability, and having durability and safety as the component parts of the air blowing device have a specific pattern by part. The present invention comprises: a motor (100) to provide a rotation force; a housing (200) in which the motor (100) is mounted, and fixed on the ceiling of a building by a fixing structure (900); a first plate (400) and a second plate (500) horizontally assembled to a collet (300) coupled to the circumference of a rotary shaft (120) of the motor (100) while being vertically separated from the each other; a plurality of blade fixing members (600) having one side assembled between the first plate (400) and the second plate (500) and the other side protruding to the outside of the first plate (400) and the second plate (500), and radially arranged from the rotary shaft (120); a plurality of blades (700) assembled to the other side of the blade fixing members (600); and an anti-falling unit (800) assembled on the edge of the second plate (500) along the circumferential direction at predetermined intervals while penetrating the first plate (400), and hooked on the bottom of the housing (200) when the rotary shaft (120) and the collet (300) are separated.</p> |
