Claims

[Scope of utility model registration request]

A combination seal consisting of a sealing element 1 and a slinger 2 installed between two mutually movable members to isolate the inside and the outside; the sealing element 1
is composed of a fitting cylindrical portion 1a and a radial portion 1b having a U-shaped bent lip 3 and a radial lip 4 on the periphery, and when this is combined with a slinger 2 having a U-shaped cross section, the fitting of the sealing element 1 Cylinder part 1
a and the outer circumferential axial portion 2a of the slinger 2 to form a labyrinth space, and the middle portion of the U-shaped bent lip 3 is connected to the radial portion 2a of the slinger 2.
The combination seal is characterized in that its tips are brought into contact with the outer circumferential axial portion 2a, and the radial lip 4 is brought into sliding contact with the circumferential surface of the inner circumferential axial portion 2c.
