Abstract
In an electric saw includes a circular saw blade, a guard cover is arranged to surround an upper portion of the circular saw blade and a dust collecting case is arranged at the rear of the guard cover for collecting chips generated during a cutting operation performed by the circular saw blade. An openable lid unit is arranged in a position along a passage through which the chips pass. The guard cover is formed into a curved shape along the circular saw blade and the passage is defined by the guard cover to extend along a peripheral edge of the circular saw blade. The lid unit includes an opening portion formed in the passage and a lid member for closing the opening portion. The lid unit is opened toward the front of the guard cover as the lid member is rotated along a rotating plane of the circular saw blade.
