PURPOSE: A glass conveying device is provided to prevent the damage of a glass caused by the wear of a bush by mounting a rotation sensing element to an end of at least more than one driving roller part. CONSTITUTION: A glass conveying device includes a plurality of driving shafts(12) rotating by rotation forces transmitted from a motor to convey a glass, and a rotation sensing part(40) mounted to at least one or more of the driving shafts for sensing the rotation of the driving shafts. The rotation sensing part includes a rotation part(32) mounted to an end of the driving shaft and formed with a plurality of holes(34) by a predetermined interval, and a sensing part(30) for sensing the rotation state of the rotation part. The sensing part includes a main body formed in the shape of U to overlap the holes, a light emitting element mounted to an end of the main body for emitting light, a light receiving element mounted to the other end of the main body for receiving light passing through the holes, and a control part for determining the abnormality of the driving shafts according to intervals of the light received by the light receiving element.
