ABSTRACT:
A circular saw (1) includes a base (2) and a main body (3) mounted on the base and provided with an upper blade guard (7). Disposed behind the upper blade guard (7) is a stopper (22) which includes an upper curved portion (23) and an lower portion (24) coupled to the curved portion (23). One end of the lower portion (24) is attached to the main body (3) with a pivot screw (25) behind the blade guard (7) so as to permit the stopper to pivot on the screw (25) in parallel with a circular blade (5). Additionally, the curved portion (23) includes an arcuate guide slot (26). The stopper (22) further includes a fixing bolt (27) screwed in a boss (29) formed on the rear surface of the blade guard. The bolt (27) includes a lever (30) to be manually operated to selectively secure the curved portion to the bolt and release the curved portion therefrom. When the curved portion (23) is released, its pivotal position relative to the main body towards the base can be manually changed. Provided on the base is a projection (32) which is abutted by the stopper (22) when the main body (3) is lowered toward the base (2). When the curved portion (23) abuts the projection's upper surface (33), the amount of the blade (5) projecting below the base (i.e., the depth of cut) corresponds to the aforementioned relative position of the curved portion (23) with respect to the base (2).
