To reduce an axial installation width of a sealing device 1 comprising an oil seal 5 mounted in an inner periphery of a shaft hole 3 of a housing 2 and slidably contacted with an outer periphery of a rotating shaft 4 and a magnetic encoder 6 mounted on the rotating shaft 4 so as to be rotated therewith, as well as to improve sealing performance, the oil seal 5 is provided with a metal ring 7 having at least a part thereof disposed at an inner periphery side of the cylindrical portion 10b in the magnetic encoder 6 so that the oil seal 5 and magnetic encoder 6 are overlapped with each other in an axial direction, and the oil seal 5 is provided with a seal lip 8e formed with a rubber-like elastic body and disposed towards an interior side A of a housing. |
