<p>PROBLEM TO BE SOLVED: To provide a lighting system hardly sticking chips and capable of maintaining excellent illuminating efficiency for many hours by solving the difficulty of maintaining the illuminating efficiency for many hours due to easily sticking the chips generated by cutting work to an electric lamp of the lighting system in a conventional lighting system provided with a lighting system for illuminating a cutting part, for example, in a cutter such as a portable circular saw. SOLUTION: The electric lamp 31 for illuminating the cutting part X is arranged in a position dislocated in the direction perpendicular to a surface from a cutting surface in a back face part of a blade case 10 for covering the side of a cutting blade 5. This constitution can maintain the illuminating efficiency for many hours by relatively minimizing the chips by dislocating the cutting blade 5 in the direction perpendicular to the surface even in a part close to the cutting part X.</p> |
