Abstract: Twisting of a locking member due to cogging torque is reduced without lowering the locking and unlocking operability for a user. A power tool includes a housing, an electric motor located inside the housing and including a permanent magnet, a shaft rotatable about an axis relative to the housing to transmit power from the electric motor, a locking member movable between a lock position and an unlock position in a nonenergized state of the electric motor and engageable with the shaft at the lock position to lock rotation of the shaft, and an abutting member that applies, to the locking member at the lock position, a force in a direction opposite to an axial torque caused by the permanent magnet and applied to the locking member.

Abstract: A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved.

Abstract: An apparatus, method and system for cutting a material involves a cutting device with a body and a base. The body attaches to the base by a swing pivot that swings to position the body. A rotary blade, powered by an electric motor of the cutting device, is associated with the body. The body with the rotary blade may descend upon a table configured to receive the material. The table is mounted on the base beneath the rotary blade. An illumination device that emits light is coupled to a sliding, support portion beneath the swing pivot to direct light toward the rotary blade. Further, a light emitting diode (LED) may be mounted within the illumination device at an angle relative to the body to illuminate the material.

Abstract: A jigsaw includes a motor, a rod having a blade attached thereto, a power transmission portion that converts rotation transmitted from the motor to vertical movement of the rod to vertically move the blade, and a counterweight that moves vertically in a direction of the vertical movement of the rod outside a range of the vertical, movement of the rod and the blade. At least a part of the counterweight is disposed so as to cross an extended line of a trajectory of the vertical movement of the rod. The counterweight moves vertically independently of the vertical movement of the rod which is produced by the power transmission portion.

Abstract: A rechargeable electric power tool includes a battery pack that is detachably provided on a housing accommodating a motor and that supplies electric power to the motor, and a tool that is driven by the motor. A standby switch and a lock-on switch are arranged at the housing. The standby switch is able to set the rechargeable electric power tool to a standby state where the rechargeable electric power tool waits for the motor to be driven. The lock-on switch is able to shift the rechargeable electric power tool from the standby state to a state where the motor is driven so as to keep the state where the motor is driven.

Abstract: An illuminator that emits light from a radially outer portion of the cutting tool toward the cutting tool includes a first light source and a second light source, and a first lens and a second lens. The first lens has a first emission surface including a first outermost portion located farthest and at a first distance from a first center axis including a first light source center of the first light source and perpendicular to the first light source. The second lens has a second emission surface including a second outermost portion located farthest and at a second distance from a second center axis including a second light source center of the second light source and perpendicular to the second light source. A distance between the first center axis and the second center axis is shorter than a sum of the first distance and the second distance.

Abstract: A jigsaw includes a housing, a motor, a blade, a roller holder and a dust collection passage. The housing accommodates the motor. The blade driven by a motor protrudes downward from a front part of the housing and moves in a reciprocating manner to cut a workpiece. The roller holder is pivotally arranged under the housing and holds a roller that is arranged between a pair of side walls facing each other. The roller abuts on a rear part of the blade. The dust collection passage formed through the housing has a dust collection port that opens behind the roller holder. The jigsaw further includes a dust collection nozzle that has a vertically long opening formed on a front face and a rear face thereof respectively, the opening on the front face being connected to the dust collection port.
