Abstract: To reduce wasteful power consumption and noise generation, a control circuit drives a motor in response to a switch being turned on after a handle detector detects attachment of an auxiliary handle and a handle gripping detector detects gripping of the auxiliary handle, controls the motor to rotate at a predetermined first rotational speed in response to the switch being turned on with the attachment and the gripping of the auxiliary handle being detected, and controls the motor to rotate at a second rotational speed lower than the first rotational speed in response to a state of a load on a tip tool being unchanged for a predetermined period of time.

Abstract: A battery-powered system includes a battery pack (10; 71; 81) connected to an electrical equipment (30; 50; 76; 86). The battery pack includes a first positive electrode terminal (11), a first negative electrode terminal (12), a first communication terminal (13), a first data input circuit (23), and a first limiting circuit (D11; D72; D82) that limits a flow of electric current in a direction from the first negative electrode terminal to the first communication terminal via the first data input circuit. The connected equipment includes a second positive electrode terminal (31; 51), a second negative electrode terminal (32; 52), a second communication terminal (33; 53), a second data input circuit (43; 63; 77; 87), and a second limiting circuit (D31; D51; D77; D87) that limits a flow of electric current in a direction from the second negative electrode terminal to the second communication terminal via the second data input circuit.

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 brushless motor (6) includes: a rotor (25), which rotates about a rotational axis (AX); and a stator (24), which is disposed around the rotor and comprises one or more coils (29). The rotor comprises a rotor core (31) and a rotor shaft (33), which is disposed in a shaft hole (60) of the rotor core. The rotor shaft includes: a thinner-diameter force-fitting segment (82), which is force-fit into the shaft hole with a first amount of force-fitting interference; and a thicker-diameter force-fitting segment (79), which is disposed at a location different from that of the thinner-diameter force-fitting segment in a front-rear direction parallel to the rotational axis and which is force-fit into the shaft hole with a second amount of force-fitting interference that is larger than the first amount of force-fitting interference.

Abstract: A pressure washer disclosed herein may include a pump mechanism configured to pressurize water supplied through a water inlet and pump out the water through a water outlet, an electric motor configured to drive the pump mechanism, and a housing that houses the pump mechanism and the electric motor. An outer surface of the housing most proximate to the electric motor may have a shape that does not allow the pressure washer to stand on its own when the outer surface is used as a placement surface.

Abstract: An audio output device has a lantern part extends along a first axis, an antenna part, an audio output part, and a control part. The antenna part has a first end and a second end that are respectively connected to a first side and a second side relative to a central part of the lantern part in a first direction parallel to the first axis. A portion of the antenna part between the first end and the second end extends in the first direction and is spaced apart from the lantern part in a direction orthogonal to the first direction. The control part is configured to cause the audio output part to output sound corresponding to a radio broadcasting wave received by the antenna part.

Abstract: A power tool includes a tool body, a motor, a handle, at least one biasing member, and at least one guide part. The handle is connected to the tool body to be pivotable and to be movable in at least a front-rear direction relative to the tool body. The handle includes a cover part covering a portion of the tool body and a grip part extending in a cantilever manner from the cover part. The at least one biasing member biases the tool body and the handle away from each other in the front-rear direction. The at least one guide part includes a first portion disposed on a portion of the tool body covered by the cover part, and a second portion disposed on the cover part of the handle and connected to the first portion to be movable in at least the front-rear direction relative to the first portion.

Abstract: An electric working machine in one aspect of the present disclosure includes a driving device, a controller, a control power source, and an operation state determiner. The control power source includes a first converter and a second converter. The control power source transitions to a first conversion state when the operation state determiner determines that the controller is in a control operation state. The control power source in the first conversion state supplies a first control current to the controller. The control power source transitions to a second conversion state when the operation state determiner determines that the controller is in a low power operation state. The control power source in the second conversion state (i) stops operation of the first converter, and (ii) supplies a second control current to the controller.
