Estimating the term…
This sealing mechanism is provided with a cap in an overall sectional configuration of a cramp iron which is made from a synthetic resin, and a resilient sealing body in an overall sectional configuration of a cramp iron. An inner surface of the cap is formed with an inserting groove in which the resilient sealing body is fitted. When the resilient sealing body is fitted in the inserting groove in the cap, this sealing body is partially protruded from inner surface of the cap. The cap is also formed with longitudinal lubricating slots on the outer surface thereof. Moreover, both side surfaces of the cap are provided with a plurality of notches at predetermined regular intervals of place which extend from the outer surface of the cap to the inner surface thereof.
A sealing mechanism for a rotary actuator, comprising a cap means in an overall sectional configuration of a cramp and a resilient sealing body also in an overall sectional configuration of a cramp, said cap means comprising a body portion and two depending leg portions, the cap means having an inner surface defined by the surface of the body portion between the leg portions and surfaces of the leg portions continuous with the surface of the body portion, a plane-shaped outer surface opposed to the inner surface, and two plane-shaped side surfaces between the inner surface and the outer surface, the inner surface of the cap means including an inserting groove into which the sealing body is fitted with a part of the sealing body protruding from said inner surface of the cap means, the plane-shaped outer surface of the cap means having longitudinal lubricating slots, and both of the plane-shaped side surfaces of the cap means respectively having a plurality of notches which extend from the outer surface of the cap means to the inner surface of the cap means.
