Abstract: A battery pack in one aspect of the present disclosure includes a first battery block, a second battery block, and a terminal portion. The terminal portion is configured to output a parallel voltage of the battery block and the second battery block connected in parallel in response to a state where a first electric working machine is connected to the terminal portion. The terminal portion is configured to output a first voltage of the first battery block and a second voltage of the second battery block individually in response to a state where a second electric working machine is connected to the terminal portion.

Abstract: A work tool includes an elongate outer housing, an elongate inner housing, a motor, a spindle, and a transmitting mechanism. The inner housing includes a first end part, a second end part, an extending part and an elastic connection part. The motor, the spindle and the transmitting mechanism are disposed in the first end part of the inner housing. The first end part is connected to the outer housing via a first elastic member. The second end part includes a power-source-related device configured to enable power supply from a power source to the motor. The elastic connection part includes second elastic members connecting the extending part and the second end part. The second elastic members are spaced apart from each other in a circumferential direction around the longitudinal direction.

Abstract: A disc grinder includes a tool main body that may include, for example, as from the front side, a drive portion, a handle portion, and a battery attachment portion. A rechargeable battery may be attached to the battery attachment portion through sliding. A brushless DC motor rotationally drives a motor shaft by electric power from the rechargeable battery. A reduction gear unit may reduce in speed the rotational drive of the motor shaft and may transmit the rotational drive to an output shaft to which a grinding wheel is mounted. The brushless DC motor and a reduction gear of the reduction gear unit may be arranged such that the rotational axis of the motor shaft and the rotational axis of the output shaft are parallel to each other.

Abstract: A representative power tool has a spindle transmitting a motor driving force to a tool accessory, a tool accessory holding member movable between a holding position and a tool accessory releasing position, a lock mechanism movable between an engaging position for locking the tool accessory holding member in the holding position and a disengaging position for releasing the lock, an inner housing housed in a body housing and houses at least part of the lock mechanism, and an operation mechanism. The operation mechanism includes a handle part, a switching part that switches the lock mechanism between the engaging position and the disengaging position according to the handle part operation, and a switching connection part that is separated from the inner housing when the lock mechanism is placed in the engaging position and comes into contact with the inner housing when the lock mechanism is placed in the disengaging position.

Abstract: A power tool enabled to detect an inadvertent rotation at higher accuracy includes a first sensor that detects a first driving information corresponding to a kinetic movement state of the tool body when the tool body is rotated around a longitudinal axis of the tool bit in the event of a working operation of the power tool, a second sensor that detects a second driving information corresponding to an output torque of the tool bit driven by the motor, and a controller connected to the first sensor and the second sensor for controlling the power tool. The controller is configured to calculate holding information corresponding to a holding force of a user to hold the tool body based on the first driving information and the second driving information and control the driving of the power tool based on the holding information.
