Abstract: A drive mechanism for pressure-gages in general, comprising a main body which can support all the members, and which is made by molding a plastic material with simultaneous embedding therein of an end of a Bourdon tubular spring, said end having fixedly inserted therein a small tube, which is also embedded in the plastics body in the same molding operation and which ensures the communication with the pressure source. The movable end of said Bourdon tube has integrally-formed thereon an eye member for connection with an S-shaped link which can actuate the indicating means of the pressure-gauge.
