Abstract: A reciprocating tool includes a motor, a motion converting mechanism, a body housing, an inner housing, a support body, and a counterweight. The motion converting mechanism is operably coupled to a motor shaft and is configured to convert rotation into a linear reciprocating motion along a driving axis. The inner housing is within the body housing and houses at least a portion of the motion converting mechanism. The support body is originally separate from the inner housing and is attached to the inner housing in the body housing. The counterweight is operably coupled to the motion converting mechanism and is configured to be driven by the motion converting mechanism. The counterweight is supported by the support body to be pivotable around a pivot axis that extends in a direction orthogonal to the driving axis. At least a portion of the counterweight is housed in the inner housing.

Abstract: A light unit is less likely to have lower light emission performance upon receiving a shock. An electric work machine includes a motor, a housing including a motor compartment accommodating the motor and a grip protruding downward from the motor compartment, an output unit located frontward from the motor and operable with a rotational force from the motor, a substrate extending above, on a left, and on a right of the output unit, and a plurality of light emitters mounted on a front surface of the substrate at intervals in a circumferential direction of the output unit. A light emitter of the plurality of light emitters nearest an apex of the substrate immediately above the output unit is at a position shifted circumferentially by a predetermined angle from the apex.

Abstract: A power tool includes a motor, an output shaft that is rotated by a rotational force of the motor, a chip-on-board light emitting diode disposed around the output shaft, and a white translucent optical member including a light refraction portion that refracts light emitted from the chip-on-board light emitting diode. In at least one cross section parallel to and passing through a rotation axis of the output shaft, a shape of the light refraction portion is line-symmetric with respect to the rotation axis.

Abstract: A rebar tying tool includes: a twisting motor, which actuates a twisting member that twists a wire, which has been wound around rebars; a main-body housing, which houses the twisting motor; and a first illumination member, which is held on the main-body housing and shines light toward the rebar. A method for tying the rebars using the wire includes first shining light emitted from the rebar tying tool toward the rebars and then twisting the wire, which has been wound around the rebars.

Abstract: An electric work machine avoids lowering the visibility of a workpiece by an operator. An electric work machine includes a motor, an output unit operable with a rotational force from the motor, a light emitter at least partially surrounding the output unit, an optical member including an outer cylinder located radially outward from the light emitter, and a light transmitter located frontward from the light emitter to allow light emitted from the light emitter to pass through, and a light shield located radially outward from the outer cylinder.
