Abstract
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.
Claims15
A miter saw comprising:
- a base means for placing a work thereon;
- a miter saw unit having a saw blade mounted thereon;
- a slide support mechanism for slidably supporting said miter saw unit relative to said base means;
- said slide support mechanism including a slide shaft and a sleeve member, said slide shaft being mounted on one of said base means and said miter saw unit, and said sleeve member mounted on the other of said base means and said miter saw unit;
- said slide shaft and said sleeve member being slidably movable relative to each other in an axial direction of said slide shaft;
- deformable first and second covers disposed on opposite sides of said sleeve member in said axial direction to surround said slide shaft;
- said first and second covers forming, around said slide shaft, a first air chamber and a second air chamber closed from the outside;
- and
- communication means for communication between said first air chamber and said second air chamber.
A miter saw comprising:
- a base means for placing a work thereon;
- a miter saw unit having a saw blade mounted thereon;
- a slide support mechanism for slidably supporting said miter saw unit relative to said base means;
- said support mechanism including a bracket, a slide shaft slidably supported in a first and a second sleeve member, said first and second sleeve member being fitted within a cylindrical support portion formed integrally with said bracket, the miter saw unit mounted on one end of said slide shaft;
- said slide shaft being slidably movable relative to said sleeve members in an axial direction of said slide shaft;
- deformable first and second covers disposed on opposing sides of said first and second sleeve member in the axial direction to surround said slide shaft;
- said first and second covers forming, around said slide shaft, a first air chamber and a second air chamber closed from the outside;
- and
- means for communication between said first air chamber and said second air chamber to enable equalization of pressure with the first and second air chamber.
