とする卓上切断機のロアーガード。 A safety guard 4 is supported on a hinge member 3 of the surface plate 1 by a fulcrum shaft 5 fixed to its base end so as to be movable up and down and held in an upwardly movable position by an interposed spring 7. A lower guard 16 rotatably attached to the bearing portion 12a of the circular saw drive shaft 11, which is integrally provided, rotates in conjunction with the vertical movement of the safety guard to shield and expose the exposed portion 14b of the saw blade 14a of the circular saw 14. The vicinity of the base end of the arm 18 to which the lower guard is freely connected via the link 20 is placed in the hinge member, and is rotatably supported by the fulcrum shaft 22 at the eccentric position of the fulcrum O of the safety guard. An eccentric part 5b is formed on the fulcrum shaft of the safety guard, and the proximal end part 18a of the arm is brought into contact with the eccentric part so that the arm rotates in conjunction with the vertical movement of the safety guard. Lower guard for tabletop cutting machine.
