Abstract
A portable circular saw has a main body (8) accommodating a motor therein, a sawing blade (4) rotated by the motor, a dust casing (3) covering the upper part of sawing blade (4), and a base (9) mounting main body (8). A plurality of partition plates (12a-12e) and a step-up portion (13) are arranged in a hollow space of dust casing (3). These plates (12a) to (12e) and step-up portion (13) have a surface perpendicular to a plane of sawing blade (4). A side wall (17) of dust casing (3) is recessed inward. Base (9) is an aluminum casting product. A link portion (11), provided on base (9), is rotatable about a pivot (18) so as to allow an angular adjustment between base (9) and sawing blade (4).
