PURPOSE:To realize easy assembly and, further, reduce pressure loss by a method wherein a first protrusion is provided on the side surface of one of the straight parts of an elastic element and pressed by a pressure spring with a vibration insulator therebetween and a second protrusion is provided on the side surface of the other straight part and supported firmly with the vibration insulators therebetween. CONSTITUTION:Flat plate shaped protrusions 1b and 1c are formed on the inner side surfaces of both the straight parts of an elastic element 1 so as to face each other. The protrusions 1b and 1c are provided near neutral planes so as not to disturb a vibration generated in the elastic element 1. The first protrusion 1b which is formed on the straight part of the elastic element 1 which is brought into contact with a rail-type stator 8 is supported by a plate-shape pressure spring 3' which is extended horizontally from a placing table 4 with a felt 5' therebetween. On the other hand, the second protrusion 1c which is formed on the other straight part is held and supported by support members 6'a and 6'b which are fixed to the placing table 4 with felts 7' therebetween. With this constitution, as the elastic element 1 is softly fixed to the placing table 4, assembly is easy and, further, movement along a direction A can be restricted. |
