A variable cutting-angle circular saw device includes a base; a rotary table 2 rotatably disposed in the central portion of the base; a bracket liftably attached to a hinge; a motor, a speed reducer, a circular saw, an outer cover, and a safety cover, all being fixed to the bracket; a fence fixed in a rearward position of the base; a clamp fixed at left- and right-hand positions of the device so as to allow a workpiece to be clamped for cutting the workpiece. A sawdust-guiding frame piece is suspended from a lower end of a rear portion of the cover so as to smoothly block a gap between the lower end of the rear portion of the outer cover and an upper surface of a curved portion in the central portion of the fence, guiding the sawdust blowing up via the blow-up port, to the inner side of the rear end of the outer cover. A sawdust accommodating chamber below the rotary table is closed at the bottom and has a substantially arcuate bag-like shape, and communication with the cover via a port at the rear thereof.
