To make a rotation operation easy by preventing the incidental rotation of a table.

As regards a flip-over saw 1, a motor 13, at the table position of a miter saw where a main body 11 is an upper side, while the main body 11 is at a top dead-center, is arranged to be positioned in the upper vicinity of the rotary shafts 5 and 5 of a table 3. Concretely, as the upper vicinity, at the position of the top dead-center of the main body 11, the center O1 of the motor 13 is set to be positioned slightly in front of a perpendicular plane S passing through the axial center O of the rotary shafts 5 and 5 to be the rotational center of the table 3, and the horizontal distance H between the center O1 and the perpendicular plane S is shortened.
