Cutting apparatus for concrete or the like

A cutting apparatus for concrete or the like, comprising:

• a main body;
• a blade cover;
• and
• a slide guide,
• wherein:
• the main body includes a body frame, wheels, a motor, and a blade, and is configured so that a cutting depth of the blade during a cutting operation is adjustable by changing a tilting angle of the body frame in a front-rear direction and a height of a front portion of the body frame;
• the blade cover includes a box-shaped casing having a size such that the blade can be entirely covered, and a slider attached to a rear surface of the casing;
• the casing is open at a bottom surface side, and has a notch for receiving a rotating shaft of the blade formed in the rear surface of the casing from a lower edge upward to a predetermined height position;
• the slider has left and right linear portions of a predetermined length and is attached so that both of the linear portions are oriented to be on an inner side and parallel to each other and also so that a predetermined gap is formed between a portion of a predetermined range including at least the linear portions and the rear surface of the casing;
• the slide guide includes left and right circular-arc portions and flaps for sandwiching the linear portions of the slider;
• the left and right circular-arc portions are disposed at a side surface of the body frame in a mutual arrangement so as to face one another in a front-rear direction of the body frame, with a rotating shaft that supports the blade being inserted therebetween;
• each flap is attached so that a predetermined gap is formed between said flap and the side surface of the body frame;
• and
• by sandwiching the linear portions of the slider between the flaps of the slide guide and the body frame and sandwiching the circular-arc portions between the left and right linear portions, the blade cover is held in a state in which the blade cover can slide in the up-down direction with respect to the slide guide and the body frame and can rotate about the circular-arc portions.
