To improve operability.SOLUTION: In a miter saw 10, a fixing mechanism 50 includes a lever 64 and a bearing 68 that regulates rotation of a support column 42 to one side in a rotating direction at a right-angle position of a support column 42. By rotating the lever 64 about an axis AL1, the fixing mechanism 50 is switched between a fixed state and an unfixed state. Further, by performing a movement operation of moving the lever 64 toward a rear side along the axis AL1, a front-rear position of a lever unit 60 (the bearing 68) is switched from a first position to a second position, so that the restriction of rotation of the support column 42 toward the one side in the rotating direction by the bearing 68 is released. This eliminates the need for an operator to operate separate operating-portions when a head portion 32 is changed from the right-angle position to a position inclined to a right side with respect to a turntable 24. Therefore, it is possible to improve the operability when changing the position of the head portion 32 with respect to the turntable 24.SELECTED DRAWING: Figure 3
