A miter saw having a bevel angle fine adjustment mechanism capable of easily providing an intended bevel angle. A clamp shaft is threadingly engaged with a tilt support. An adjustment knob and a planetary gear mechanism are concentrically and rotatably disposed over the clamp shaft. The planetary gear mechanism includes a sun gear integral with the adjustment knob, a pair of planetary gears meshedly engaged with the sun gear and orbitally moved about the sun gear, and a ring gear meshedly engaged with the pair of planetary gears. A planetary gear support member rotatably supports the planetary gears. By the orbital motion of the planetary gears, the gear support member is rotated about an axis to rotate an output gear. An arcuate gear meshed with the output gear is fixed to the support portion. By the rotation of the adjustment knob, the output gear is deceleratingly rotated to laterally tiltably move the support portion.
