Real-straight line motor

The invention relates to a real-straight line motor and a method of manufacturing the real-straight line motor. The real-straight line motor comprises a shell body, the shell body is provided with an outlet, a silica gel body and an electric heating component arranged inside the silica gel body are arranged inside the shell body, and the electric heating component is connected with an external power supply through a circuit. According to the real-straight line motor, a traditional electronic power source is abandoned creatively, and a mode that a mechanical component is used as an intermediate component is adopted, namely the property that the silica gel body expands when heated is utilized, expansive force of the heated silica gel body is used for doing work, the real-straight line motor belongs to an electric actuator which directly acts and uses rectilinear motion mechanical energy, transforming and conducting of an intermediate component are not needed, and therefore the real-straight line motor is charac
