Abstract
A portable cutting device capable of changing and adjusting a cutting depth of a circular saw blade relative to a base with lesser labor. A saw cover is pivoted on the base to change the cutting depth. An adjustment guide extends from the base in a pivotally moving direction of the saw cover in a superposed relation to the saw cover. A tightening unit is disposed to the saw cover at a position superposed with the adjustment guide and the saw cover for providing a selective tightening between the saw cover and the adjustment guide. The tightening unit includes a shaft part extending through the saw cover and the adjustment guide, a pivot operation part pivotally movable about an axis of the shaft part, and an urging part disposed over the shaft part and movable by the pivot operation part in the axial direction of the shaft part.
