  • Patent number: 10605368
    Abstract: A sealing apparatus sealing a gap between two members mutually relatively rotatable about an axis in an internal combustion engine, the sealing apparatus comprises an elastic body portion. The elastic body portion is an elastic body including an annular attaching portion attached to one of the two members and centered about the axis, and a seal portion in close contact with another of the two members in a manner in which the other of the two members is slidable. The seal portion includes an annular seal lip portion centered about the axis and an annular dust lip centered about the axis on an atmospheric side on an opposite side of a sealed fluid side with respect to the seal lip portion. The seal lip portion includes a lip tip portion which is an annular projecting body projecting toward the axis and grease is applied to the seal lip portion. The grease contains at least one of a synthetic hydrocarbon oil and a mineral oil as a base oil and has a low temperature starting torque of 25 N·cm or less at ?30° C.
