PROBLEM TO BE SOLVED: To provide a fan with a concealed 360°oscillating mechanism. SOLUTION: The fan includes a main housing; a pivot member 60; a first driving motor 70; an oscillating mechanism 80; and a rotary blade. The main housing includes a through-hole 31 formed at the front end, position fixing members 32 formed on inside lateral face ends, and a connecting member 33 formed on the inside rear end surface, and the pivot member includes a hollow pivot frame 61, pivotal shafts 62 at both ends of the frame and pivot holes 63 disposed at both upper and lower ends of the frame. The first driving motor includes a first rotating shaft 71, and connecting bars 72 provided to extend to both upper and lower ends of the pivot member 60. The oscillating mechanism is attached to between the back of the first driving motor and the rear end surface of the main housing, and a second end of the oscillating mechanism is eccentrically rotated by a first end thereof, and the rotary blade is connected and fixed to the first rotating shaft. Since the first driving motor is positionally fixed by the pivot member and the oscillating mechanism, and the first driving motor is cyclically rotated 360°to average the force received by each component within the main housing while changing the blowing direction, the operation of the fan is stabilized, and a stress fatigue phenomenon within the oscillating mechanism is reduced.
