摘要： An impact drill minimizing transmission of vibration to a handle gripped by a user's hand. A spindle extends through a main frame and is movable in its axial direction and rotatable about its axis. A first ratchet is rotatable and axially movable together with the spindle. A second ratchet is axially movable but unortatable. The first ratchet has a first serrated surface and the second ratchet has a second serrated surface in confrontation with the first serrated surface. In an impact drilling mode, the first serrated surfaces is brought into abutment with the second serrated surface so that the spindle is reciprocally moved in the axial direction. A first spring is interposed between the main frame and the second ratchet to urge the second ratchet toward the first ratchet. A second spring is interposed between the main frame and the second ratchet to urge the second ratchet away from the first ratchet. In the impact drilling mode, the second ratchet is always out of contact from the main frame and is floatingly maintained within the main frame.

摘要： A power tool providing a smooth cooling air flow discharging through discharge windows formed in a housing. In the housing a radial fan is rotatably provided for cooling a heated motor. A cooling air generated by the radial fan is discharged through the discharge windows. Each discharge window has a rectangular shape having an upstream side and a downstream side in the rotating direction of the cooling fan. A chamfered portion is provided at least at the upstream side and in an inner peripheral surface of the housing, so that a thickness of the housing wall is gradually small in the rotating direction. The chamfered portion increases an effective area of the window for discharging air.

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, which can realize the reduction of noise without inviting the reduction of a fastening ability and which can improve the durability of a damper while preventing its damage. The impact tool includes a rotary impact mechanism mounted on a spindle to be rotationally driven by a motor, so that rotary impact is applied to a tip tool by transmitting the rotary impact intermittently from a hammer through an anvil to the tip tool. A plurality of pawls are formed on two half members of the anvil in the axial direction. A rubber damper is disposed in a space between the pawls arranged alternately in the circumferential direction of the two half members. The minimum sectional area of the space formed between the pawls is set larger than the sectional area of the rubber damper.
