PROBLEM TO BE SOLVED: To provide a portable electrical circular saw capable of restraining the generation of noise without deteriorating the cooling performance of a fan. SOLUTION: In this cutting machine, the wall surface on this side, in the rotating direction of the fan 7, of at least a part of a partition wall 5d, is inclined in the radial direction of the fan 7 pivoted at its rotating center axis. Further, the inclination is directed where it proceeds in the counter-rotating direction of the fan 7 toward the outside of the radial direction. COPYRIGHT: (C)2005,JPO&NCIPI
