Abstract: There is provided a cleaning device for a liquid jet head which can efficiently clean a jet plate attached with a guard member while preventing cleaning liquid from being leaked along an opening of the guard member. The cleaning device for the inkjet head includes a holder moving relatively to the inkjet head, wherein the holder includes a jet section for jetting the cleaning liquid toward a nozzle guard of the inkjet head, a wipe part which has a width in a width direction perpendicular to a moving direction of the holder smaller than a width of an opening of the nozzle guard, and which wipes a nozzle plate due to a movement of the holder, a first suction section disposed ahead of the jet section and the wipe part in the moving direction of the holder, and a second suction section disposed posterior to the jet section and the wipe part in the moving direction of the holder.
