Abstract: An electric working machine including a motor, an electric-power supply unit, a control unit, and a signal processing unit. The signal processing unit performs a signal control process for sending and receiving a signal to and from the signal processing unit and an external device, and receives at least a stop-command signal from the external device. The control unit stops the electric power supply to the motor in a case where the stop-command signal is received at the signal processing unit when the electric power supply from the electric-power supply unit to the motor is in process.

Abstract: In a rack and pinion mechanism 80, a driving-side pinion gear 83 and a driven-side pinion gear 86 are provided to be coaxially rotatable relative to each other within a predetermined angle range. Because of this construction, in a case where a time when a driver 3 reaches an advancing end position and contacts an advancing end damper 19 deviates from a time when a weight device 5 reaches a retracting end position and contacts a moving end damper 7, an excessive external force is not applied to engaging teeth 81a and 82a by relative rotation of the pinion gears 83 and 86. Thus, due to this construction, durability of the rack and pinion mechanism 80, where end impacts are absorbed through elastic deformation, is improved.

Abstract: A hammer drill has a body housing having a motor housing and a gear housing formed in one piece. An electric motor is fixed to the motor housing. A motion converting mechanism, a striking mechanism and a tool holder which form a striking mechanism part are housed in the gear housing so as to be movable with respect to the gear housing. During hammering operation, the striking mechanism part moves with respect to the gear housing under a biasing force of a coil spring, so that vibration caused by the hammering operation is reduced.

Abstract: An electric power tool includes a relay, an electric circuit, and an operation member. The relay has a coil, contacts, and an on-switch. The relay is configured such that the coil is energized when contacts are closed by an on-switch being pressed, and contacts are held in a closed state by an electromagnetic force of coil when coil is energized. In the electric circuit, electric power from power source is supplied to motor and coil of relay, and contacts are connected in series between power source and motor. The operation member is configured to move in reciprocating manner between tool stop position at which the motor stops and tool drive position which the motor runs, where the operation member is configured to locate away from on-switch of the relay at the tool drive position and configured to press the on-switch at a position other than tool drive position.

Abstract: A power tool for driving an accessary removably held between first and second clamp parts includes a first shaft having the first clamp part, a second shaft for moving the second clamp part, a holding member movable relative to the second shaft, a moving member for moving the holding member, and a biasing member for biasing the moving member. The second shaft is disposed inside the first shaft. The holding member enables the second clamp part and the first clamp part to hold the tool accessary therebetween in a first position, and disables the second clamp part and the first clamp part from holding the tool accessary in a second position. The moving member moves the holding member from the first position to the second position, and the biasing member biases the moving member when the holding member is located in the second position.
