Abstract

An actuating device (2) is adapted for use in a mechanical fan. The mechanical fan includes a rotating base (3) and a plurality of fan blades (4). The actuating device (2) includes a plurality of first holders (21) adapted to be connected to the rotating base (3), a plurality of rotating members (23), and a driving strip (26). Each rotating member (23) has a lower end portion (232) connected rotatably to a respective first holder (21), an upper end port ion (231) adapted to be connected co-rotatably to a respective fan blade (4), and a gear portion (233). The driving strip (26) is trained on and meshes with the gear portions (233) of the rotating members (23). During rotation of the rotating base (3), the fan blades (4) are driven by a centrifugal force to synchronously swing with respect to the first holders (21), respectively, to a stretched-out state.
