PURPOSE: A roller for a transfer device is provided to reduce a deflection amount and to disperse a deflected part on a surface, which touches a transferring object, into multiple parts when deflection is generated by a weight of the transferring object or a self-load. CONSTITUTION: A roller for a transfer device comprises a center roller(100), an outer roller(200), and a spacer unit(300). Both ends of the center roller are rotatably supported. The outer diameter surface and the inner diameter surface of the center roller are separately arranged in the outer roller. The spacer unit is separately arranged between the center roller and the outer roller. A ratio of a first distance(L1) from an end of the outer roller to the spacer unit at the closest position, and a second distance(L2) from the spacer unit to the other adjacent spacer unit is 1:1.5-2.5. |
