ABSTRACT:
A circular saw includes a worktable, a mounting seat extending upwardly from the worktable for mounting a motor thereon, a blade supporting unit pivotally mounted on the mounting seat at a pivot end so that an opposite free end is turnable to be close to and away from the worktable, and a saw blade shaft mounted rotatably on the blade supporting unit about a blade axis parallel to an output shaft axis of an output shaft of the motor and having a saw blade mounted thereon. The saw blade shaft is coupled to the output shaft by a drive transmitting unit which transmits driving force of the output shaft to the saw blade shaft so as to rotate the saw blade.
