A gas combustion type driving tool includes a feed piston/cylinder mechanismby which a feed piston, engaged/disengaged to/from a connecting fastener housed in a magazine, is reciprocated in a fastener feed direction in which the piston is fed toward a nose partand a retracting direction opposite to the feed direction. The feed pistonis constantly spring-urged in the feed direction, and part of a combustion gas is supplied to a feed cylindervia a gas pipeprovided between the combustion chamberand the feed piston/cylinder mechanism, thereby operating the feed pistonin the retracting direction against a spring. In the gas combustion type driving tool, filtersfor cooling a combustion gas are located in the gas pipe
