<p>A cutting machine comprising a motor (6) having a motor shaft (6a), a circular saw blade (1) having a saw blade shaft (1a) parallel with the motor shaft (6a), a housing (2) storing the motor (6) and the circular saw blade (1) and having a handle (14) at its rear side (R1), a surface plate (4) connected to the housing (2), a start end gear (7a) fixed to the motor shaft (6a), a terminal end gear (7b) fixed to the saw blade shaft (1a), counter gears (7c, 7d) disposed between the start end gear (7a) and the terminal end gear (7b). The start end gear (7a), the terminal end gear (7b), and the counter gears (7c, 7d) are meshed with each other to transmit the rotation of the motor (6) to the circular saw blade (1) in the same rotating direction after its speed is reduced. The counter gears (7c, 7d) are positioned at the rear (R1) with respect to a plane including the motor shaft (6a) and the saw blade shaft (1a).</p> |
