PROBLEM TO BE SOLVED: To provide a sealed rolling bearing securing sufficient sealing performance even if the same is used under a condition where mud water splashes. SOLUTION: A bearing space between an inner ring 1 and an outer ring 2 is sealed by an inner and an outer two contact seals 5, 6. Mud water can be completely shut off by the outer contact seal 6 and mud water is prevented from adhering on the lip 5c and a seal slide surface 1a of the inner contact seal 5 by providing the inner and the outer two lips 6c, 6d on the outer contact seal 6. Consequently, sufficient sealing performance can be secured even if the bearing is used under a condition where mud water splashes. COPYRIGHT: (C)2006,JPO&NCIPI
