Claims

[Scope of utility model registration request]

There are two members that move relative to each other, and one member is fixed to the other member whose relative movement amount is detected,
In addition, a slit-shaped opening is opened, and the opening of the hollow case is arranged on both sides of the opening of the hollow case so that the longitudinal direction of the opening is arranged along the moving direction of the other member, and the end portion of the opening is in the shape of a seal lip and comes into butt contact with the hollow case. two flexible lip members respectively arranged along the longitudinal direction; A connecting rod is provided for transmitting a signal to a displacement detector housed therein, and a recess is formed at least at one longitudinal end of the opening to allow expansion and contraction of the lip member, and the depth of the recess is adjusted to the extent that the lip member swells. Sealing device for displacement detectors with a length greater than or equal to the maximum length.
