PURPOSE: A spindle structure for an atomizer is provided to offer good durability while preventing a porous air bearing from being damaged by shaft impact, and to reduce replacement cost and times for damaged air bearing. CONSTITUTION: A spindle structure for an atomizer comprises the followings: a cylinder body(10) formed to a hollow pipe shape, and having a stepped cylinder structure; a rod-shaped shaft(20) penetrated inside the cylinder body; an upper porous air bearing(31) installed at the top of the cylinder body and the top of an inner circumference; an upper ceramic bearing(40) embedded on an upper stepped part; a lower porous air bearing installed at the bottom of an inner circumference of the cylinder body; and a lower ceramic bearing embed on a lower stepped part of the cylinder body.
