PROBLEM TO BE SOLVED: To prevent the leakage of electromagnetic waves by providing an electrical contact interface between first and second metallic components contacted at an intersection supporting oil with a third highly surface-conductive component in the first metallic component, and including a means for applying forces thereto. SOLUTION: First and second components 2 and 3 are mutually movable at an intersection thereof, a contacting and sealing member 4 is a circle having a size fitted to the cylindrical surface of the intersecting part 1, and disposed in a part in the groove 5 of the component 2. The component 2 has surfaces 8 and 9 brought into contact with a member 4 for supporting and giving electrical continuity, and the member 4 is brought into contact with the component 3 by a force 10. The member 4 is made of a material having a relatively high surface conductivity relatively similar in hardness to the metals of the components 2 and 3. An oil film 11 is located in an interface between the member 4 and the component 3, and hydraulic fluids in a cylinder are used also as lubricant between the components at the intersecting part 1. Thus, the leakage of an electromagnetic wave from the cylinder is prevented. |
