PROBLEM TO BE SOLVED: To efficiently collect dust at the front corner of a suction head in the suction head. SOLUTION: The suction head includes a suction chamber 9 which is provided at the lower part of a suction head body 1 and has an intake 8 on the lower side; a pipe 6 provided at the rear of the suction body 1; an air channel 13 provided between the inner side of the top of the suction nozzle body 1 and the outer side of the top of the suction chamber 9; an opening 14 provided at the front of the air channel 13 to communicate between the suction chamber 9 and the air channel 13; and a blower device 15 provided at the rear of the ventilation channel 13 to communicate with the ventilation channel 13 for sucking outside air. The blower device 15 sucks outside air from the intake 8 and discharges air from the opening 14 via the air channel 13, so that the stable exhaust wind force can be fed to the opening 14 by the blower device 15. Since the opening 14 is disposed in front of the inside of the suction chamber 9, the dust at the front corner is sent out to the pipe 6 side with the air discharged from the opening and the suction air generated inside the suction chamber 9, so that the dust can be efficiently collected without being blown away.
