携帯用丸鋸
Document Type and Number:
Japanese Patent JP4119601
Kind Code:
B2
Abstract:
A portable circular saw includes a base. A saw blade has a portion projecting downward from the base. A saw-blade cover conceals at least a part of the saw blade. A projection provided on the saw-blade cover protrudes in a direction away from the saw blade. The projection has a lower surface extending across a first plane which is parallel to an axis of rotation of the saw blade, and which contains a tangent to an outer circumference of the saw-blade at a point of intersection with a second plane including a lower surface of the base. Chips fly from the point of intersection along a direction in the first plane. The lower surface of the projection inclines relative to a line perpendicular to the tangent so as to change a path of a portion of flow of the chips toward a forward side as viewed in a cutting direction.
