摘要： Provided is a working machine with improved durability. A nail driver (working machine) includes a hitting portion that is formed in a rod shape extending about an axis line, an injection portion that abuts on an outer peripheral surface of the hitting portion, thereby guiding a movement of the hitting portion toward one side in the axial direction, and a supply portion that energizes a fastener toward one side in a direction intersecting with the axial direction, thereby supplying the fastener to the injection portion. The hitting portion has a tip part, and a center part provided at a position different from that of the tip part in the axial direction. At least a part of an outer peripheral surface of the tip part (tip part outer peripheral surface) on an anti-feeder side with respect to the axis line protrudes from an outer peripheral surface of the center part (center par outer peripheral surface) on a supply portion side with respect to the axis line.

摘要： A driving tool capable of suppressing the consumption of power for actuating an actuator is provided. The driving tool includes a striking unit, a trigger valve, a housing, a trigger, and a contact member. When an operation force is applied to the trigger and the contact member comes into contact with a workpiece and is actuated, the driving tool switches from the standby state to the actuated state. The driving tool further includes a stopper having a first position where the actuation of the contact member is blocked and a second position where the actuation of the contact member is enabled and an actuator configured to drive the stopper. The actuator holds the stopper at the second position by being supplied with electric power when the stopper is at the second position.

摘要： A driving tool having a striking unit and a driver unit includes a solenoid configured to switch between a first state and a second state by being actuated by the supply and stop of the electric power, wherein the driver unit has a first drive state in which the striking unit can be actuated and a second drive state in which the actuation of the striking unit is blocked, wherein the first state enables the driver unit to switch from the second drive state to the first drive state and the second state blocks the driver unit from switching from the second drive state to the first drive state, and wherein an actuation direction of the solenoid and the moving direction of the nail are arranged so as to intersect each other.

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.

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.
