Abstract: One aspect of the present disclosure provides an electric-powered lubricator including a first manual switch, an electric motor, a drive circuit, a pump, and a control circuit. The control circuit controls, while the electric motor is being driven, the drive circuit such that the electric motor decelerates from a preset rotational speed in accordance with a difference between (i) a setting value and (ii) a calculated value. The setting value corresponds to a desired count of reciprocation of a plunger in the pump. The calculated value corresponds to a calculated count of reciprocation of the plunger.

Abstract: A reducer appropriately selects from three or more variable speeds to match multiple operational modes. An impact driver includes a motor, a reducer that reduces rotation from the motor to select from three or more variable speeds, a plurality of actuators to be actuated by the rotation reduced by the reducer, and a switcher that selects, from the plurality of actuators, a specific actuator to be actuated in a predetermined operational mode. The switcher causes the reducer to cooperate with the selected specific actuator and actuates the reducer at a predetermined variable speed of the three of more variable speeds corresponding to the predetermined operational mode of the selected specific actuator.

Abstract: A core drill includes: a motor having a stator and a rotor, which is rotatable relative to the stator; a speed-reducing mechanism; an output shaft that, in the state in which a core bit is mounted thereon, is rotated by the rotational force of the rotor transmitted via the speed-reducing mechanism; and a battery-mounting part, on which a battery pack is mounted. A stator outer diameter, which is the outer diameter of a stator core of the stator, is 75 mm or more; and a stator length, which is the dimension of the stator core in an axial direction, is 30 mm or more.

Abstract: A cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to control electric power supply to the motor; a motor control device configured to control the motor via the motor drive circuit; a switching element arranged on an electric power supply path to the motor drive circuit; a switch circuit arranged separately from the motor control device and configured to switch the switching element between a conduction state and a non-conduction state; and an operation member arranged on the cart and configured to be operated by a user. The cart may operate in a manual mode in which the motor is driven when the operation member is on and the motor is stopped when the operation member is off, and in an automatic mode in which the motor is driven regardless of whether the operation member is on or off.

Abstract: A power tool having a hammer mechanism includes a tool body defining the driving axis, a motor housed in the tool body, an elongate handle connected to the tool body in a cantilever manner and extending in a direction intersecting the driving axis, and at least one biasing member disposed between the tool body and the handle. The motor has a motor shaft that is rotatable around an axis parallel to the driving axis. The handle includes a first end portion connected to the tool body to be pivotable around a pivot axis relative to the tool body, a free end, and a grip part disposed between the first end portion and a free end of the handle. The at least one biasing member is configured to pivotally bias the tool body and the handle such that the grip part and the tool body move away from each other.

Abstract: A power tool having a hammer mechanism has a tool body that houses a motor and a driving mechanism and extends in a front-rear direction; a handle including a grip part that extends in an up-down direction orthogonal to the front-rear direction behind the tool body and has a lower end formed as a free end and is arranged below the driving axis; and a plurality of biasing members configured to elastically connect the tool body and the handle. The biasing members include at least one first biasing member arranged above the driving axis in the up-down direction, and at least one second biasing member arranged below the driving axis in the up-down direction. In this power tool, a biasing force of the at least one second biasing member is larger than a biasing force of the at least one first biasing member.

Abstract: A driver-drill (1) includes a motor (6) having a stator (61) and a rotor (62); an output part (8) including: a spindle (81), which is disposed more forward than the motor and, in response to application of a rotational force transmitted from the rotor, is rotated around a rotational axis (AX) extending in the front-rear direction; and a chuck (82), which is mounted on the spindle; and a speed-reducing mechanism (30), which is configured to rotate the output part at a rotational speed that is lower than the rotational speed of the rotor but at a higher torque. The maximum fastening torque of the output part is 160 N·m or more.
