A miter saw including a base portion and a main body portion laterally tiltable and vertically pivotable. The main body portion includes a circular saw blade whose one side is provided with a power transmission mechanism. The mechanism includes a motor shaft pulley fixed to a motor shaft of a motor, a saw blade shaft extending in parallel with the motor shaft and an intermediate shaft extending in parallel with the saw blade shaft and positioned between the motor shaft and the saw blade shaft. On the saw blade shaft, a first saw blade shaft bearing, a flanged abutment portion, a gear and a second saw blade shaft bearing are arrayed in an order from the circular saw blade. On the intermediate shaft, a pinion meshedly engaged with the gear, a first intermediate shaft bearing in alignment with the second saw blade shaft bearing, an intermediate shaft pulley in alignment with the motor shaft pulley and a second intermediate shaft bearing are arrayed in this order from the circular saw blade. The gear and the pinion are positioned closest to the circular saw blade, which permits an axial thickness of the abutment portion to be reduced for reducing entire axial thickness of the power transmission mechanism.
