Claims

[Scope of Claim for Utility Model Registration] A housing that houses a motor, a gear cover that covers a saw blade driven by the motor, and a gear cover that guides the saw blade during cutting and is movable to adjust the depth of cut. A base attached to the gear cover, a link attached to the base and formed with a guide groove corresponding to the adjustment range of the cut amount, and the link is fixed to the gear cover and the base is adjusted to a predetermined position as appropriate. the link is included in the gear cover, the bolt passes through the guide groove, and the link is held between the bolt head bearing surface and the gear cover. The notch of the electric circular saw is configured such that the bolt is inclined in a direction away from both the base and the housing when viewed from the fixation surface with the link. Volume adjustment mechanism.
