摘要： Realized is a driving device capable of controlling driving timing of a blade and driving timing of a feeder independently. The driving device of the present invention has a housing having an injection path, a blade hitting a nail supplied to the injection path, an electric motor, a controller controlling drive of the electric motor, a magazine accommodating connected nails, and a supply, mechanism sequentially supplying the connected nails, which are accommodated in the magazine, to the injection path. The supply mechanism has a reciprocable feeder backward and forward, an energizing member energizing the feeder forward, and a stopper holding a position of the backward moved feeder against energization of the energizing member. Then, holding the position of the feeder by the stopper is released based on control of the controller.

摘要： A driving tool includes: a striking unit striking a fastener by being actuated in a first direction; a rack on the striking unit; a wheel; and a second transmission portion on the wheel and capable of being engaged with and released from the rack. The striking unit can be actuated in a second direction when the second transmission portion is engaged with the rack, and the striking unit can be actuated in the first direction when the second transmission portion is released from the rack. The second transmission portion includes: a tooth portion arranged along a rotation direction of the wheel and turned in a predetermined direction to be engaged with and released from the rack; and a movable piece actuated in the predetermined direction to be engaged with the rack and actuated in a different direction from the predetermined direction to be released from the rack.

摘要： A driver has: a strike section moving in a first direction to strike a fastener; and a bumper contacting the strike section and restricting the range of movement of the strike section in the first direction. The driver further has: a support section for supporting the bumper; a connection section connected to the support section and disposed in a direction intersecting the first direction; a drive section supported by the connection section and moving the strike section in a second direction; a first receiving section which, when the strike section moves in the first direction to hit the bumper, receives a load acting on the support section in the first direction; and a second receiving section which, when the strike section moves in the first direction to hit the bumper, receives a load acting on the support section in the circumferential direction about a first centerline of the drive section.

摘要： A driving tool capable of moving a striking unit in a direction of striking a fastener when electric power supply to a switching mechanism stops is provided. Further, a driving tool capable of setting a timing of generating a function of preventing moving force transfer from a contact member to a gas supply mechanism is provided. A driving tool including an operational member, a contact member, a pressure chamber, a striking unit and a driving unit has a first mode and a second mode that can be selected by an operator. When the second mode is selected, if a state with the operator operating the operational member and with the contact member being away from the workpiece is within predetermined time, movement of the contact member is not prevented. When the second mode is selected, if the state with the operator operating the operational member and with the contact member being away from the workpiece exceeds the predetermined time, the movement of the contact member is prevented.
