A reciprocating apparatus is provided to improve energy efficiency by decreasing use of consumption-oriented energy required for an electromagnet and using attraction and repulsion of a permanent magnet. A reciprocating apparatus(100) includes a cylinder(10), a pair of first permanent magnets(30a,30b), a piston(40), a pair of electromagnets(50a,50b), and a piston rod(20). A moving hole(15) is formed on an outer side of the cylinder. The first permanent magnets are arranged on both ends of the cylinder inside. The piston is located between the first permanent magnets. A second permanent magnet(40a,40b) is combined on the both ends of the piston. The piston reciprocates inside the cylinder. One end of the piston rod is connected through the moving hole. |
