Disclosed is a remote controller. The remote controller comprises a first panel and a second panel. The first panel is connected to the second panel by using a rotating connecting mechanism. The rotating connecting mechanism comprises a fixation base fixed to the first panel, a rotating shaft fixed to the second panel, and a sliding component. The sliding component comprises: an arc-shaped sliding rail disposed in the circumference direction of an outer sidewall of the rotating shaft; elastic pieces disposed on the fixation base in the axial direction of the rotating shaft and provided with circular holes; and rolling balls disposed between the arc-shaped sliding rail and the circular holes in an abutted mode. The arc-shaped sliding rail is fitted to the rolling balls in a sliding mode. Two ends of the arc-shaped sliding rail are higher than the middle of the arc-shaped sliding rail in the axial direction of the rotating shaft. The size of the remote controller in the present invention is reduced on the basis that function buttons have sufficient space; and the first panel and the second panel are effectively prevented from rubbing against each other when the remote controller is turned on or turned off, and accordingly, function buttons of the first panel can be prevented from being abraded and damaged.
