PROBLEM TO BE SOLVED: To reduce in size of an engine without increase of weight, increase of vibration, and change in a rotating direction. SOLUTION: This device comprises a cylinder 20 formed inside an engine body, a piston 21 disposed slidably inside the cylinder, and a crankshaft 22 connected to the piston 21 via a connecting rod 31. A center axial line L2 is offset, with respect to a line L1 which passes a shaft center of the crankshaft 22 and is parallel with the cylinder 20, to a side opposite to a direction of thrust force F acting on the piston 21. |
