<P>PROBLEM TO BE SOLVED: To provide a power tool miniaturized in constitution while stabilizing supply voltage and prevented from the situation of thermally damaging a control circuit. <P>SOLUTION: This power tool 11 is provided with a grip part 14 gripped by an operator and having a built-in battery 19; a motor 15 integrally provided near one end part of the grip part 14 and rotationally driven with the battery 19 as a power supply; and a body part 12 with a built-in control circuit 18 for controlling the rotating state of the motor 15. A capacitor 20 of comparatively large capacity connected in parallel to the battery 19 is built in the grip part 14. <P>COPYRIGHT: (C)2004,JPO |
