Abstract: A drive manipulation member is configured to be allowed to move to a drive position when an interlock member is at a first position and to be prohibited from moving to the drive position when the interlock member is at a second position. The drive manipulation member is supported rotatably about an axis with respect to the second housing, and is provided with first and second portions extending from the axis in different directions. The first portion is configured to be manipulated by the user. The second portion is provided with a switch operation portion configured to operate a switching unit and an interlock engaging portion configured to engage with or contact with the interlock member. The switch operation portion and the interlock engaging portion are located at different positions from each other in a direction parallel to the axis.

Abstract: A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

Abstract: An electric oscillating tool has an electric motor having an output shaft, an eccentric shaft that is connected to one end region of the output shaft, and a weight that is connected to the other end region of the output shaft. A blade as a tool accessory is driven to reciprocally rotate around a spindle by reciprocating motion of the eccentric shaft in a transverse direction of the electric oscillating tool. The weight is driven to cancel out the inertial force of the eccentric shaft, so that the output shaft is stably rotated.

Abstract: An interlocking adapter in one aspect of the present disclosure includes a current path, an electric load, a switch, and a controller. The controller turns on and off the switch in synchronization with a change of an alternating-current voltage received from an electric outlet of an electric apparatus in response to reception of an interlocking command signal from a working machine so as to supply a load current from the electric outlet to the electric load. The controller turns on and off the switch at a specified ratio of a time every ½ cycle of the alternating-current voltage.

Abstract: A working machine includes: an output shaft to which a tip tool is attachable; a housing rotatably supporting the output shaft; and a protection cover attached to the housing so as to cover an outer periphery of the tip tool which is attached to the output shaft. The protection cover is configured to be displaceable between a processing position to expose a part of the outer periphery of the tip tool to thereby allow cutting of a workpiece, and a protecting position to cover the outer periphery of the tip tool more than in the processing position, and is biased by a biasing member to be displaced from the processing position to the protecting position.

Abstract: In an electric power tool which houses a motor and a controller for controlling drive of the motor, the controller has a circuit board on which electric components are mounted and a heat radiation member which radiates heat of the electric components. The heat radiation member has a facing part which faces the circuit board in parallel to a board surface of the circuit board. The facing part is provided with steps by which a distance between the facing part and the board surface of the circuit board varies. Furthermore, the facing part of the heat radiation member is provided with a first facing part in which a relative distance with respect to the board surface of the circuit board is reduced.

Abstract: An impact tool includes a motor, a first hammer, an anvil, and a second hammer. The first hammer is configured to be rotated by driving of the motor. The anvil is configured to be hammered in a rotation direction by the first hammer. The second hammer is configured to be switchable between a state being linked and a state not being linked to the first hammer. The impact tool ensures selections of a first hammering mode in which only the first hammer hammers the anvil and a second hammering mode in which the first hammer and the second hammer hammer the anvil.

Abstract: A rotary tool includes a motor, a final output shaft, a housing, a detecting mechanism, an interrupting mechanism and a solenoid. The motor includes a motor body and a motor shaft. The final output shaft is configured to be rotationally driven by torque transmitted from the motor shaft. The housing houses the motor and the final output shaft. The detecting mechanism is configured to detect a motion state of the housing. The interrupting mechanism is provided on a transmission path of the torque from the motor shaft to the final output shaft, and configured to interrupt transmission of the torque. The solenoid includes a linearly movable actuation part and is configured to mechanically actuate the interrupting mechanism via the actuation part based on the motion state of the housing detected by the detecting mechanism.
