摘要： A power tool can receive two different auxiliary handles in a replaceable manner. A power tool includes a tool body, a main handle, a cylindrical handle mount to which a first auxiliary handle or a second auxiliary handle is attachable and having a groove, the first auxiliary handle, and the second auxiliary handle. The first auxiliary handle includes an arc-shaped first band, a band holder that changes the diameter of the first band, and a first protrusion engageable with the groove. The second auxiliary handle includes an arc-shaped second band having a cutout in an axial direction, a fastener that changes the diameter of the second band, and a second protrusion engageable with the groove.

摘要： A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit.

摘要： A power tool includes a housing and an electric motor supported within the housing. The housing includes a main housing portion that defines a rear opening. The electric motor includes an output shaft supporting a rotor assembly for rotation about a motor axis. The electric motor also includes a stator assembly surrounding the rotor assembly, and a rear end cap. The rear end cap supports a rear motor bearing that rotatably supports the output shaft at a rear end. A portion of the rear end cap resides within the rear opening to close the rear opening.

摘要： A power tool includes a motor, a housing, a battery holder and a cushion. The battery holder is held by the housing to be movable at least in a first direction relative to the housing. The battery holder is configured to removably receive a battery for supplying electric power to the motor. The cushion is held by the housing such that the first direction intersects the cushion. When the battery is attached to the battery holder, the cushion is directly or indirectly disposed between the battery and the housing.

摘要： A power tool is less likely to generate noise. A power tool includes a housing, a field fixed to the housing and including a field coil, an armature rotatable relative to the field and including a commutator, two brushes that come in contact with the commutator, and a brush holder unit holding the two brushes. The brush holder unit includes two contact rails electrically connectable to the field coil, two first terminals that each come in contact with either of the two contact rails, two second terminals each electrically connectable to a corresponding brush of the two brushes, and a choke coil located between at least one of the two first terminals and at least one of the two second terminals.

摘要： A hammer drill comprises a drive mechanism including a spindle, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, and a hammer lockout mechanism adjustable between a first mode and a second mode. The hammer drill further comprises a clutch adjustable between a first state and a second state. The hammer drill further comprises a collar rotatably coupled to the housing and movable between a first rotational position in which the hammer lockout mechanism is in the first mode and the clutch is in the first state, a second rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the first state, and a third rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the second state.

摘要： [Object]
The object of the disclosure is to provide a structuring technique which contributes to the rationalization of dispositioning parts and operability with respect to a striking tool in which usual operation is defined as a striking operation to the downward in a state that the striking tool is downwardly dropped by the own weight of the striking tool.
[Embodiment to Achieve the Object]
A striking tool 100 in which striking operation is done in a state that the striking tool 100 is downwardly dropped by the own weight, having a motor 210 with an output shaft to drive the drive mechanism, a controller 260 to control the motor 210, a functional member 280 to assist the striking operation and a controller case 270 to hold the controller 260, wherein the controller case 270 further holds the functional member 280.

摘要： An electric working machine with the same or more prevention or suppression of the transmission of the vibration than that of a related art because of having the less components and the less man-hours for assemblies than those of the related art is achieved. A hammer drill includes a motor serving as a driving source and is equipped with a drill bit driven by a driving force that is output from the motor. The hammer drill includes a main-body housing and a handle housing forming at least a part of an outer shell, and the main-body housing and the handle housing are connected to each other through an elastic body to be relatively movable. The elastic body is formed on the main-body housing and the handle housing by a double-layer molding, and is a part of a continuous resin cover covering surfaces of the main-body housing and the handle housing.
