摘要： An electrical power tool (1) includes a housing (10,20,30), an electrical motor (21), a motion conversion mechanism (36), a counterweight holding member (73), a counterweight (74), and support members (71,72). The electrical motor (21) is accommodated in the housing (10,20,30). The motion conversion mechanism (36) is configured to convert a rotary motion of the electrical motor (21) into a reciprocation motion. The counterweight holding member (73) extends in a direction perpendicular to directions of the reciprocation motion and is capable of being elastically deformed in the directions of the reciprocation motion. The counterweight (74) is supported by the counterweight holding member (73) and is capable of reciprocating in the directions of reciprocation motion together with the counterweight holding member (73). The support members (71,72) are positioned away from the counterweight (74) by a predetermined distance for supporting the counterweight holding member (73) to the housing (10,20,30). The counterweight (74) is interposed between or among the support members (71,72).

摘要： An impact tool is provided that can efficiently reduce the vibration resulting from the striker and that does not lead to a larger design even with the use of a counterweight mechanism. A counterweight mechanism is provided in a motion converter housing, facing the handle. The counterweight mechanism is positioned between a center of gravity of the impact tool and the grip of the handle and is positioned above the control substrate. The counterweight mechanism is equipped with a first support, a second support, a weight support member, and a counterweight.

摘要： A screw driver capable of avoiding co-rotation of an end bit and a motor in case of sharp shooting the end bit with a groove in a head of a screw. A co-rotation preventing mechanism is engageable with an end bit mounting portion when the end bit mounting portion is at a frontward position to prevent the end bit mounting portion from being rotated in the forward direction and to allow the end bit mounting portion to rotate in the reverse direction. The preventing mechanism is disengageable from the end bit mounting portion when the end bit mounting portion is at the rearward position to allow the end bit mounting portion to rotate in both forward and reverse directions.

摘要： A spring clutch mechanism for transmitting a driving force of a driving part to a driven part, including a first part, a second part, and a spring disposed between the first part and the second part. The first part is connected to the driven part. The second part is connected to the driving part and is rotatable relative to the first part coaxially therewith. The first part has a first end provided with a frusto-conical portion having a first tapered surface, and the second part has a second end formed with a recess provided with a second tapered surface in contact with the first tapered surface. the first part and the second part are aligned linearly and coaxially in a state that the first end is inserted into the second end maintaining contact of the first tapered surface with the second tapered surface.

摘要： A first switching member, having a claw portion engageable with a claw portion of a first gear, is slidably mounted on a crank shaft without causing any relative rotation therebetween. A first urging member resiliently urges the first switching member so that the claw portion of the first switching member is engaged with the claw portion of the first gear. A second switching member, having a claw portion engageable with a claw portion of a second gear, is slidably mounted on an intermediate shaft without causing any relative rotation therebetween. A second urging member resiliently urges the second switching member so that the claw portion of the second switching member is engaged with the claw portion of the second gear.
