A throttle control device for a carburetor having a throttle valve for adjusting air-fuel intake volume to an engine of a power tool, the throttle control device comprising: a throttle lever fixed to a throttle shaft of the carburetor which is arranged to open or close the throttle valve of the carburetor; an elastically deformable tube having a first end connected to a connection point on the throttle lever, the connection point being spaced from a rotating center of the throttle lever, and an intermediary section fixed at a first fixing position, the first fixing position being disposed on a housing of the engine and spaced from the connection point by a predetermined distance; and a throttle wire slidably accommodated in the tube and having a first end fixed at a second fixing position, the second fixing position being disposed outside the elastically deformable tube and at a distance from the first end of the tube, and a second end arranged to be manipulated by means of a throttle control lever so that the throttle wire moves relative to the tube, wherein the elastically deformable tube has a curved portion between the connection point and the first fixing position, the curvature radius of which changes due to the movement of the throttle wire relative to the tube, and wherein at least a portion of the elastically deformable tube disposed between the connection point and the first fixing position is covered by a detachable protecting cover of the power tool.
