Patent ID: 8631733

Claim:
A miter saw, comprising: a base unit on top of which target material is placed; a table unit provided on the base unit so as to be capable of rotating about a first axis; a swing unit which is provided on the table unit so as to be capable of rotating about a second axis substantially orthogonal to the first axis, and which swings up and down above the table unit; and a cutting unit provided on the swing unit and having a flat motor provided with a stator and a rotor, the rotor having an output shaft, with one of the rotor and the stator having a coil disc provided with a plurality of coil pieces arranged in the circumferential direction about the output shaft when seen in the axial direction of the output shaft and the other of the rotor and the stator having a magnetic flux generation unit for generating magnetic flux that passes through the coil disc in the axial direction of the output shaft, a rotating blade rotation shaft on which a rotating blade can be mounted and an axial direction of the rotating blade rotation shaft is arranged so as to be substantially parallel to the axial direction of the output shaft of the flat motor and the axial direction of the second axis, and a power transfer unit for transferring the power of the flat motor to the rotating blade rotation shaft, wherein the power transfer unit comprises a first gear provided on the output shaft of the flat motor, a rotating blade gear anchored to the rotating blade rotation shaft, and an intermediate gear engaging with the first gear and the rotating blade gear and anchored to an intermediate shaft rotatably supported on the cutting unit, the flat motor and the intermediate gear are positioned such that in the state in which the swing unit is fully swung in the direction approaching the cutting unit on the table unit, the outer edge of the flat motor and the outer edge of the intermediate gear are farther from the table unit in the axial direction of the first axis than the rotating blade rotation shaft, when seen in the axial direction of the rotating blade rotation shaft, and the cutting unit has an interlocking unit that can interlock directly with the intermediate shaft.
