摘要： A fuel gas has a gas including at least 40 weight % or more of 1-butene and propane, or at least 56 weight % or more of 1-butene and propylene. A combustion type power tool is driven by the fuel gas. A compressed gas container for a combustion type power tool has an inner side vessel filled with the fuel gas. When the fuel gas includes propane, 1-butene may be equal to or higher than 59 weight % and equal to or lower than 95 weight %. When the fuel gas includes propylene, the 1-butene may be equal to or higher than 70 weight % and equal to or lower than 96 weight %.

摘要： A power tool providing a smooth cooling air flow discharging through discharge windows formed in a housing. In the housing a radial fan is rotatably provided for cooling a heated motor. A cooling air generated by the radial fan is discharged through the discharge windows. Each discharge window has a rectangular shape having an upstream side and a downstream side in the rotating direction of the cooling fan. A chamfered portion is provided at least at the upstream side and in an inner peripheral surface of the housing, so that a thickness of the housing wall is gradually small in the rotating direction. The chamfered portion increases an effective area of the window for discharging air.
