In a gas internal combustion type nailing machine, a tubular-shaped sleeve is fixed between a movable housing and a fan. Between the movable housing and sleeve, an annular space portion is formed. In such portions of the sleeve as existing respectively upwardly and downwardly of the fan, there are formed communication holes and in communication with the annular space portion. Mixed gas blown out by the fan flows through the lower communication hole and returns from the annular space portion to the combustion chamber through the upper communication hole.
