In an internal combustion engine with a reciprocating movement which uses gasoline, diesel fuel or other fuels to generate forces when fuels attain explosive combustion, the piston is pushed in the inner cylinder. The motion of the piston with the reciprocating movement (straight motion) is transferred to a crank shaft having rotation motion, or the rotation motion of the crank shaft is transferred to the piston having straight motion (reciprocating movement). By such transfer, in order to use in compressed feed for fluids, when the connecting rod is provided with a universal joint type and a ball joint type, although the relative position errors and right angle are staggered within a given range, abnormal friction, noises and vibrations never take place. Accordingly, pollutions such as noise, vibration and noxious exhaust gases are dramatically reduced, fuels are surprisingly and significantly saved, and the life of the machine is doubly increased. Further, the piston is divided into a crown part and a skirt part, and the crown part is used with a piston ring in a conventional way. However, the skirt part is attached to a metal roller mounted on a metal bracket, or a metal plate or spring, and the piston is provided with an expansion property. Accordingly, the gap or clearance between the cylinder and the piston is completely removed, and maximum smoothing motion takes place when the piston is moved up and down. By such smoothing action of the piston, a state without tilt and slap is realized. Vibrations and noises due to tilt and slap are completely removed.
