PURPOSE:To improve the accuracy of conversion and the durability of the electric-pneumatic relation converter in the caption by composing a fulcrum to support one end of a flapper in a contilever manner, of two plate springs made of good conductor and crossing each other at right angles, and connecting respective lead wires of an exciting coil to these plate spring. CONSTITUTION:In a mobili-coil type electric-pneumatic relation converter, a fulcrum to support one end of a flapper 1 in a cantilever manner is composed of two plate springs 21 and 22 made of good conductor and crossing each other at right angles, and respective lead wires 10a and 10b of an exciting coil 4A are connected to the plate springs 21 and 22. The plate springs 21 and 22 can be, thus, used as both the fulcrum and a terminal, and the lead wires 10a and 10b can be handled on the flapper 1 so that the lead wires 10a and 10b may expand and contract to cause no excessive tension. The movement of flapper 1 is, accordingly, made accurately in proportion to an input signal and the accuracy of conversion and the durability can be improved.
