<P>PROBLEM TO BE SOLVED: To provide a sealing device of a rolling bearing without losing a fastening margin or becoming excessive even in a state of relatively moving an inner ring and an outer ring in the axial direction by imparting a preload to the bearing, while using a low torque type seal of imparting the fastening margin in the axial direction. <P>SOLUTION: This sealing device is provided for exhibiting sealability intended in low torque, without taking into consideration directivity when incorporating the bearing, by imparting the fastening margin to any of surfaces 1c and 6c in any one of first and second lips 51b and 51c, even if the inner ring 1 and the outer ring 2 move in the axial direction, by putting the first and second lips 51b and 51c in an inserted state between these surfaces 1c and 6c, by arranging the first and second surfaces 1c and 6c mutually opposed at an interval in the axial direction substantially orthogonally in the axial direction of the rolling bearing on the inner ring 1 side, by forming the first and second lips 51b and 51c mutually projecting in the inverse direction in the axial direction in an inner peripheral part of the seal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
