A rotating piston engine, wherein a rotor performs perfectly concentric rotation without involving eccentric rotation and wherein compressed gas can be changed into combustion gas by using a simple structure. A rotating piston engine is provided with a mechanism in a gear housing (61), and the mechanism is configured such that, on the slightly inner side of outer peripheral portions of a rotor (13), rotating pistons (21g or 21h) maintain positions thereof in the top-bottom and left-right directions while performing revolving and rotating motions. The mechanism allows the rotating pistons (21g or 21h) to avoid stationary cylinder heads (34m or 34p) while allowing the rotating pistons (21g or 21h) to smoothly slide. Accordingly, every moving portion performs a smooth pure circular motion. Further, a compression combustion-side piston head (29p) of the rotating piston (21g or 21h) has a gap (29q) through which compressed gas moves and which is located between a compression combustion-side cylinder head (34p) and the rotating piston (21g or 21h), and gas in an engine volume chamber moves from a compression chamber to a combustion chamber through the gap (29q). As a result, the compressed gas can simply and reliably move to the combustion chamber.
