Abstract
A gas combustion type driving tool includes an output unit, a grip, a fuel container storage unit, a battery mounting unit and a coupler. The output unit includes a combustion chamber. The grip is connected to a lower surface of the output unit. A fuel container is detachably attached to the fuel container storage unit. A battery pack is detachably attached to the battery mounting unit. The coupler is configured to take air in. The fastener is driven out by combustion pressure when mixed gas of combustible gas supplied from the fuel container and compressed air supplied from outside via the coupler is ignited. The coupler is disposed on a lower end side of the grip. The gas combustion type driving tool includes a pipe configured to connect the coupler and the combustion chamber.
