PURPOSE: A light sensing type axial center conforming device for two shafts is provided to observe concentricity and error components of parallelism between two shafts in real time simultaneously and conform the centers of the two shafts with each other with high precision in a short time, wherein the use of a low output light emitting unit is possible since a hollow light refracting unit has no loss of light. CONSTITUTION: A light sensing type axial center conforming device for two shafts includes a light emitting unit(21) positioned in the right center of a sectional surface of a reference shaft(100) for radiating light beams, a collimator lens(23) attached to the reference shaft for converting the incident light beams to parallel light beams, a hollow light refracting unit(22) attached to the reference shaft and formed with a circular slot in the center for passing all incident light beams or remains after refracting the incident light beams partially, a first photosensitive plate(25) attached to the reference shaft to be positioned oppositely to the optical divider in a vertical direction for sensing light beams refracted by the hollow light refracting unit, an insertion mirror(27) attached to a subordinate shaft(200) for reflecting and passing incident light beams partially, and a second photosensitive plate(26) positioned in the right center of the subordinate shaft for sensing light beams passing the insertion mirror.
