PROBLEM TO BE SOLVED: To increase air flow while inhibiting increase of noise and vibration in a blasting mechanism capable of freely changing a blasting direction in a regular direction and a reverse direction.
SOLUTION: A mechanism is constructed in such a manner that wind is generated in the regular direction by blasting blades 36 when angle of the blasting blades 36 in relation to a rotor 21 driven and rotated in a fixed rotary direction A1 is changed from a neutral position to the regular direction and wind is generated in the reverse direction by the blasting blades 36 when angle of the blasting blades 36 is changed from the neutral position to the reverse direction. An edge part 36a in a rotary direction upper side in a base part side section of the blasting blade 36 is constructed to be positioned more upper side in a rotary direction from a support shaft core P1 side as it separates more from the rotor 21. End part side section of the blasting blade is set with keeping backward angle B1, B2 in relation to the rotary direction in such a manner that edge parts 37c, 37d in the upper side and a lower side of the rotary direction in an end part side section of the blasting blade 36 are positioned more lower side in the rotary direction as it separates more from the rotor 21.
