Abstract
In a battery-driven tool, comprising a motor equipped with a fan and air windows arranged on the casing where the motor is positioned and for sending cooling air generated by rotation of the fan to outside, the object of the present invention is to send hydrogen gas generated by overdischarge to outside so that hydrogen gas is not accumulated in the battery chamber, and to exclude undesirable effect on the designing of the battery-driven tool. To attain the object, the motor chamber to accommodate the motor equipped with the fan is communicated with the battery chamber where the battery is accommodated.
