A table saw has a height and inclination adjustable saw blade which is mounted on and rotatable with a blade shaft that is driven by a motor. A support seat is movable relative to a mounting frame, and supports the blade shaft. A shaving collecting member is disposed in the vicinity of the saw blade to collect wood shavings. A casing is secured to the support seat, and is communicated with the shaving collecting member. An impeller is disposed rotatably in the casing, and is mounted on a driven shaft that is coupled to the blade shaft so as to permit rotation of the impeller when the motor is in operation, thereby drawing wood shavings from the shaving collecting member to the casing and out of a discharge port in the casing.
