An electric fan comprising a motor to retain and drive vanes, an annular main body to retain the motor and to serve as an air flow passage of the fan, a pair of pivots which are provided on the main body, have their axes on a phantom straight line substantially perpendicular to the axis of rotation of the vanes and are symmetrical with respect to said axis of rotation, and a pair of support plates which are rotatably connected with each other and with the main body by means of the pivots, the support plates being of a shape which surrounds the main body and does not hinder the movement of the main body on the pivots. The fan can serve as a table fan, a circulator, a wall fan or a window fan by selectively changing the relative position between the main body and the support plates.
