Abstract
A portable electric circular saw which operates on a rechargeable battery is disclosed. The circular saw comprises a housing for accommodating a motor driving a circular saw blade operatively connected thereto, the rechargeable battery supplying electricity to the motor, and a handle projecting atop the housing, the motor having an output shaft arranged transversely of the housing and connected to a drive spindle carrying the saw blade and arranged in parallel relationship with the output shaft. The motor and the battery are disposed within the housing, to be arranged along the cutting direction of the saw blade, so as to properly distribute the weight of the saw in the longitudinal direction, which is the cutting direction of the saw blade. The handle is of generally U-shaped configuration, having an elongated top grip and legs at opposed ends, which join the top of the housing at respective portions upwardly of the motor and the battery, with the top grip extended longitudinally along the cutting direction of the saw blade, such as to provide a properly balanced saw structure, which effectuates easy hand operation to advance the saw.
