Attic fans and apparatus for supporting the drive motors of attic fans, the attic fans being of the type having a housing connected around the sides of a rectilinear aperture through a wall, usually the ceiling of a home or building, the housing having a circular opening within which radially disposed fan blades mounted on a central shaft are rotated. In the attic fan shown herein, the blades are supported between spaced plates rotatively carried on the shaft. The shaft is supported at its lower end by a plurality of radially disposed supports, and is supported at its upper end by a single radial disposed support. The drive motor is supported at one side of the circular opening through the housing by a rod extending from the upper radial support to the housing. A support plate element pivotally connected to the rod has upper and lower inturned portions which engage the motor. The inturned portions of the support element have lugs engaged by a pair of straps which are bolted together at their adjacent ends so that the straps may be tightened around the motor mounting surfaces.
