According to the present invention, a rolling bearing comprises: an outer wheel where an external trajectory is installed; an inner wheel where an inner trajectory corresponding to the external trajectory is installed, is installed inside the outer wheel; and a plurality of rolling elements stored and installed between the inner trajectory and the outer trajectory. A mounting groove concavely formed on one axial cross-sectional surface of the outer wheel or the inner wheel, and the mounting groove comprises two slopes. An opening area of the mounting groove is smaller than a floor area of the groove, and the mounting groove has a cut portion formed in one among the external trajectory or the internal trajectory. A filling member is installed in the mounting groove, and comprises a bonding surface corresponding to the slope. Moreover, the slope and the bonding surface are tightly bonded, and the filling member comprises an auxiliary trajectory filling the cut portion. The purpose of the present invention is to accurately fixate a position of the filling member. |
