An axial flow cylinder of pneumatic tool, including: a cylinder body formed with an internal cylinder chamber; a rotary shaft rotatably disposed in the cylinder chamber along an axis of the cylinder body; and a predetermined number of movable wheels and fixed wheels mounted in the cylinder chamber. Multiple oblique first vents are annularly formed on each movable wheel at equal intervals. Multiple oblique second vents are annularly formed on each fixed wheel at equal intervals. The first and second vents are inclined in reverse directions. The movable wheels and the fixed wheels are interlaced with each other. The fixed wheels are fixedly disposed in the cylinder chamber without possibility of rotation. The movable wheels are synchronously rotatable with the rotary shaft. After high-pressure air flows from the intake into the cylinder chamber, the movable wheels and rotary shaft are driven and rotated by the high-pressure air. The air flows along the axis of the cylinder body between the vents of the movable wheels and fixed wheels and then is exhausted from the exhaust ports. In operation, the vents of the cooperative movable wheels and fixed wheels compress the air.
