Abstract
A driving tool includes a main body, a trigger, a contact member and a control unit. The main body has a combustion chamber configured to be filled with fuel and compressed air. The trigger is configured to operate an ignition device to combust a mixture of the fuel and the compressed air filled in the combustion chamber. The contact member is brought into contact with a driving target member to enable an operation of the trigger. The control unit is configured to start an injection of the fuel when the contact member is turned on, and to complete an injection of the air after the trigger is turned on.
