In the exemplary embodiment, an electric rotary fan has a fan head including a rotary motor and a fan blade, the fan blade rotated by the motor for producing an air stream. A pair of rubber bushings are each disposed between the fan head and a stand and each have a hole though the bushing and a key displaced from the hole, the holes of both bushings being coaxially aligned on a horizontal pivot axis. A pair of fasteners each pass through the associated bushing's hole to affix the fan head to the stand such that each fastener and its associated bushing cooperate to allow forced pivoting of the fan head relative to the stand the pivot about the pivot axis. The keys prevent relative pivoting between the bushings and the fan head by each engaging a mating tab hole in the fan head. |
