Rolling bearing having improved sealability

A rolling bearing, comprising:

• a first member having a raceway for rolling elements formed on one side of the first member;
• a second member provided to be spaced apart from the first member in a radial direction and having a raceway for the rolling elements formed on one side of the second member;
• the rolling elements provided between the first member and the second member;
• and
• a sealing member provided in an axial end portion of the rolling bearing between the first member and the second member,
• wherein the sealing member is formed in a structure in which an elastic sealing portion is attached to a frame,
• the elastic sealing portion comprises a first sealing portion formed on one end portion of the frame and a second sealing portion formed on the other end portion of the frame,
• the first sealing portion is inserted into and mounted to a coupling groove formed in the second member,
• the second sealing portion comprises an axial sealing lip extending in an axial direction from the frame and a radial sealing lip extending in the radial direction from the frame,
• the axial sealing lip and the radial sealing lip of the second sealing portion are positioned adjacent to the first member and are configured to perform a sealing in a non-contact manner,
• the radial sealing lip of the second sealing portion is formed in a shape corresponding to a sealing groove formed in the first member and is accommodated in the groove, and
• a groove is formed at an axial outer side of the radial sealing lip to have a shape recessed obliquely and inwardly with respect to the axial direction.
