A technique for improving the cooling performance of a combustion chamber in a combustion power tool is provided. The combustion power tool includes first and second combustion chambers (121, 122) which are filled with flammable gas, a partition (123) that separates the first combustion chamber (121) from the second combustion chamber (122), openings (125, 128) that arc formed in the partition (123) and serve to communicate the first combustion chamber (121) with the second combustion chamber (122), and a drive section (151) that is actuated to perform a predetermined operation by moving toward a front end by combustion pressure. Combustion gas flows from the first combustion chamber (121) to the second combustion chamber (122) in a direction around a central axis of the second combustion chamber (122) while flowing along an inner wall of the second combustion chamber (122). |
