PURPOSE:To design a support frame to economize its material, by securing a rotary support shaft to a connecting rod for the electric motor of an electric fan, and fitting the shaft rotatably in a support member which supports a rocking ring rotatably. CONSTITUTION:A connecting rod 3 is coupled at one end to a rotary shaft 2 and secured at the other end to a rotary support shaft 4 which serves to support an electric motor 1 rotatably. When the rotary support shaft 4 is rotatably fitted directly in a support member 7 which supports a rocking ring 6, the electric motor 1 is supported only by the support member 7. A support frame can thus be designed to make the thickness of its plastic material extremely small to economize the material.
