A main seal lip 32 has a two-step lip structure including a first lip 32a and a second lip 32b and a plurality of protrusions 34 extending in the direction of the shaft are formed on sliding contact surface of the second lip 32b, thereby improving frictional force characteristics and, at the same time, improving sealing performance.
