SEAL AND KINEMATIC DEVICE USING THE SAME

PROBLEM TO BE SOLVED: To provide a seal capable of stably securing contact pressure of a lip and capable of improving foreign matter removability and lubricant retentivity by making the lip easily bendable in a desired direction, and a kinematic device using the same.SOLUTION: An elastically-deformable seal body 11 having an annular shape surrounding a shaft 2 includes the lip 12 which is formed at an inside end in a radial direction orthogonal to a central axis C of the seal body 11, and an adjustment part 13 which is different in deformation amount due to an external force F from the lip 12. In a longitudinal sectional view including the central axis C, the lip 12 includes a vertical surface 16 which is directed to one side in the direction of the central axis C and which is extended perpendicularly to the central axis C, and an inclined surface 17 which is directed to the other side in the direction of the central axis C and which is gradually extended toward the one side as it is headed toward a radial inside. The adjustment part 13 is arranged on the radial outside of the vertical surface 16.
