摘要： An impact tool includes a hammer that is moved in an axis direction while being rotated by an action of a cam mechanism provided for a spindle and an anvil to which a rotational force and a striking force are applied by the hammer. A rear end surface of a striking part of the hammer is obliquely formed and has two mountain-shaped inclined surfaces. A striking part of the anvil is formed with two mountain-shaped inclined surfaces. By the inclined surfaces, even when the motor is stopped at a state where the hammer gets on the anvil, the hammer is moved forwards in the axis direction by an action of a spring and is then stopped.

摘要： An impact tool includes a housing, a spindle, a bearing, an anvil, and a percussion mechanism. The spindle is accommodated in the housing and is driven to rotate by a drive source. The bearing is accommodated in and engaged with the housing. The bearing is disposed in front of the spindle. The anvil is coaxially and rotatably connected to the spindle and is rotatably supported by the bearing. The anvil is formed with an mounting hole at a front end thereof. The mounting hole allows a tip tool to be mounted therein. The anvil and the bearing define a contact surface on which the anvil and the bearing rotate relative to each other. The percussion mechanism is configured to transmit a rotation movement of the spindle to the anvil as rotary percussive force. The bearing is formed with an oil supply channel allowing oil to be supplied from a rear end side of the bearing to the contact surface.

摘要： In a microcomputer-controlled rechargeable battery accommodating unit, such as battery pack, of the type having only positive and negative terminals, when the battery voltage is lower than the lowest limit level that the battery is usable, the drive voltage to boot and operate the microcomputer is generated based on the voltage supplied from a battery charger, since the battery voltage is not as high as to generate the drive voltage. Such a low-voltage battery is charged in a precharge mode precedent to a regular charge mode.
