PURPOSE: To improve further a sealing property by fixing one end of a core bar directly to the lower side end of an inner ring, while connecting a lip part of an elastic body seal slidably to the lower side end face of an outer ring to seal the interior of a bearing. CONSTITUTION: One end 11a1 of a core bar 11a is shaped to be bent axially and fixedly fitted to the outer diameter of the lower side end of a inner ring 6'a in a lower side conical roller bearing 6'. Also, the core bar 11a extends the other end to the outer ring 6'b side. A rubber seal 11b having a lip part 11b1 slidably connected to the lower side face of the outer ring 6'b with an interference is attached fixedly to the other end 11a2 of the core bar 11a. Thus, the sealing property can be improved and the lower side conical roller bearing 6' can be prevented effectively from intrusion of foreign matters.
