SOLUTION: In this hermrtically sealing device provided with plural outer races 1, spacers 2 and tapered rollers 3 and two inner races 4, the two inner races 4 are arranged so as to be butted by forming a cylindrical part 4a on its inside. Moreover, a peripheral stepped part is formed on the side of butting part of this cylindrical part and sealing member 6 consisting of a core bar and elastic sealing member provided with a radial lip part and side lip part is arranged so as to extend over these two peripheral stepped parts. |
