Seal member (5) includes an encoder (10) on the side of the flanged portion (3) of said seal member (5) that is opposite the side facing the other seal member (15). Seal member (15) includes an elastic element (16) formed in such a manner as to be supported by the flanged portion (14) of said seal member (15).
