Workability and endurance of a working machine is improved with a simple configuration. A working machine includes: an ejecting portion; a striking portionstriking a fastener; and a magazinefeeding the fastener to the ejecting portion. The magazineincludes: a plate-shaped base memberextending in a front and back direction Band configured to catch the fastener to be movable in the front and back direction B; a feederswitchable between a contact state representing contact with the fastener caught with the base memberand a contactless state representing contactless with the fastener at time of movement in the front and back direction B; and a guiding portion guiding movement of the feederin the front and back direction B. The working machine includes a detectordetecting a position of the feederin the front and back direction B

Working machine

A driving tool capable of suppressing the increase in the number of components is provided. The driving tool includes an ejection unitto which a fastener is supplied and a striking unit capable of moving with respect to the ejection unitso as to drive the fastener supplied to the ejection unitinto a workpiece, and the driving tool further includes a first push levercapable of contacting with and separating from the workpiece and capable of moving with respect to the ejection unit, a second push levercapable of moving in conjunction with the first push lever, and a blade guideand a coverhaving a function to guide a movement of the first push leverand the second push leverwith respect to the ejection unitin a predetermined direction.

Driving tool

A nailer for suppressing misfire while keeping operability. In a first mode, a control circuit drives a drive source when a second ON determination is made and a first ON determination is made in a state where a second operation unit is maintained at a second ON position, and when the drive source is driven and then a second OFF determination is made in a state where a first operation unit is maintained at a first ON position, the control circuit does not drive the drive source again unless returning to the initial state. In a second mode, the control circuit drives the drive source when the first ON determination is made and the second ON determination is made in a state where the first operation unit is maintained at the first ON position. A second OFF determination time in the second mode is longer than in the first mode.

Working tool

A driver capable of suppressing increase in a load torque of a motor when a striking mechanism is moved by the torque of the motor against a force of a first moving mechanism is provided. The driver includes a striking mechanismmovable in a first direction Band a second direction Bopposite to the first direction Band a first moving mechanism configured to move the striking mechanismin the first direction Bto strike a fastener, and the driver further includes a motor, a second moving mechanismrotated by the torque of the motor and configured to move the striking mechanismin the second direction against a force of the first moving mechanism, and torque suppression mechanismsA toH configured to suppress increase in the torque of the motor when the striking mechanismis moved in the second direction B

Driver, striking mechanism, and moving mechanism

Provided is a driving machine capable of stabilizing a relationship between timing when a first movable member starts operating in a first directing and timing when a second movable member starts operating in a second direction. The driving machine including a first movable memberoperable in a first direction Dand a second direction D, and a second movable memberoperable in the first direction Dand the second direction Dhas a first regulating mechanism, a second regulating mechanism, and a third regulating mechanism, and the third regulating mechanism is held in a first state when the first movable memberis prevented from operating in the first direction D, and the third regulating mechanismswitches from the first state to the second state when the first movable memberis allowed to operate in the first direction Dand operates.
