Miter saw
 A miter saw includes a base for placing a work thereon, a miter saw unit having a saw blade mounted thereon, and a slide support mechanism comprising a slide mechanism having a slide shaft mounted on one of the miter saw unit and the base, and a sleeve member mounted on the other of the miter saw unit and the base. The sleeve member is slidably movable relative to the spline shaft in an axial direction of the slide shaft, and the rotational position of the sleeve member is fixed relative to the slide shaft around an axis of the spline shaft. First and second covers are disposed around the slide shaft on opposite sides of the sleeve member forming first and second air chambers in communication with each other.
