The maximum tightening torque is 140 N·m or more. Overall length (La), which is the distance—in the front-rear direction parallel to the rotational axis—between a rear-end portion of the motor-housing part and a front-end portion of the anvil, is 100 mm or less. The hammer has a base portion, a front-side ring portion protruding forward from the base portion, and hammer projection portions protruding radially inward from the front ring portion.

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.
An electric ratchet wrench as one example of the ratchet wrench includes an electric motor, a holder that rotatably holds a socket via a one-way clutch mechanism, and a spindle configured to convert a driving force from the motor into a reciprocating rotation motion of the holder. A space is provided between the socket and the holder. The space includes large interval portions and small interval portions. The small interval portions are adjacent to the large interval portions in a rotation direction (lock direction) of the socket and have distances smaller than distances of the large interval portions. Additionally, the one-way clutch mechanism includes columnar locking pins disposed between the spaces and have a diameter with a size equal to or less than the distances of the large interval portions and exceeding the distances of the small interval portions.
A dust collecting attachment includes a dust suction portion and a main body. The main body has a dust collection passage communicated with the dust suction portion. The dust suction portion has a negative pressure by exerting a suction force to the dust collection passage from a hose. The dust suction portion includes an inner pipe through which a tip tool passes, a first dust suction flow passage, and a second dust suction flow passage. The first dust suction flow passage opens a first suction opening to a side of a workpiece in an outside in a radial direction of the inner pipe and is communicated with the dust collection passage. The second dust suction flow passage opens a second suction opening to an opposite side of the workpiece in the outside in the radial direction of the inner pipe and is communicated with the dust collection passage.

An electric work machine (1) includes: a brushless motor having a stator disposed around a rotor (30); and an output part driven by the rotor. The rotor has a rotor core (31) and first and second magnetic-pole parts (34S, 34N) disposed around a circumferential direction of the rotor core. When the induced voltage of the brushless motor is given as Va, the power-supply voltage of the brushless motor is given as Vb, the rotational speed of the brushless motor is given as ω, a first induced voltage constant, which is expressed by Va/ω, is given as Ea [V/krpm], a pole-pairs count, which is the number of the first magnetic-pole parts or the second magnetic-pole parts, is given as Pi, and a second induced voltage constant, which is expressed as Ea/Pi, is given as Eb [V/krpm·pole-pairs count], the motor satisfies the condition: Eb≤0.025×Vb.

A power tool efficiently cools a motor and a brush, with a distance for insulation left between an inlet and an urging member. A power tool includes a motor, an output unit, a fan, a housing accommodating the motor and the output unit, having an inlet to suck in air from outside in response to rotation of the fan and an outlet to discharge the air sucked in, and accommodating the motor along a flow of the air between the inlet and the outlet, a brush retainer downstream from the inlet and including a brush and a conductive urging member urging the brush against a commutator, and a nonconductive cover located between the urging member and the inlet and covering the urging member.
A dust collecting attachment includes a dust suction portion and a main body. The dust suction portion has a suction opening through which a tip tool is allowed to pass. The main body has a dust collection passage communicated with the dust suction portion and connectable to an external hose. The main body includes a suction space, an air vent hole, and an air vent operation portion. The suction space is communicated with the dust collection passage and has a suction port opening to a workpiece. The air vent hole opens the suction space to outside. The air vent operation portion normally closes the air vent hole and opens the air vent hole by a predetermined operation. The air vent operation portion is operated together with an operation of removing the main body from the workpiece to open the air vent hole.

A battery pack includes at least one rechargeable battery cell disposed within an outer case. The outer case has an upper surface having at least one terminal opening that exposes at least one terminal electrically connected to the at least one rechargeable battery cell; a bottom wall; side surfaces extending perpendicularly from the bottom wall; and four protruding portions respectively protruding downward from four corners of the bottom wall. The four protruding portions are configured such that, when the four protruding portions of the battery pack contact a flat surface, only the four protruding portions contact the flat surface and a central portion of an exterior surface of the bottom wall does not contact the flat surface.
