PROBLEM TO BE SOLVED: To provide a combustion power tool which rationally exhausts combustion gas by a simple structure. SOLUTION: This combustion power tool has: a first combustion chamber 121 and a second combustion chamber 122 in which inflammable gas is filled; an ignition device 131 provided in the first combustion chamber; a bulkhead part 123 for partitioning the first combustion chamber from the second combustion chamber; a communicating hole arranged in the bulkhead part to communicate the first combustion chamber with the second combustion chamber; and a driving part 151 for performing predetermined machining work by utilizing combustion pressure generated by combustion of inflammable gas in the combustion chambers. The combustion gas after combustion in the second combustion chamber is led into the first combustion chamber by moving the bulkhead part onto a second combustion chamber side and reducing volume of the second combustion chamber and is exhausted to the outside together with combustion gas in the first combustion chamber.
