PURPOSE:To smooth adjustment operation and to prevent contactness from lowering by making it possible to fix a short disk and push body, composed of an elastic- substance tongue piece with a conductive contact at its tip circumference, at attention points by individually moving the both. CONSTITUTION:Short disk body 3 is a conductor disk with an external diameter a little bit smaller than the internal diameter of outside tube 1 of a coaxial cylindrical feeder and has slanting surface 5 at its outer circumference. Push body 4 has at its tip outer circumference a skirt body formed of elastic-substance tongue piece 7 equipped with conductive contact 6. Then, rod 10 with spline 9 is screw-cut 8 and inserted into inside tube 2 of a feeder, and projections 11 and 12 are formed on disk 3 and push body 4 and fixed in spline 9 to allow disk 3 and push body to slide independently along inside tube 2. Then, the disk and push body are provided with nuts 13-15 to make it possible to support the both at desired positions. Consequently, an adjustment can be made smoothly without making the disk in contact with the outside tube during its position adjustment. |
