Abstract: The present disclosure provides a cutting device capable of more reliably preventing shavings from entering a gap formed between a dial and a main body. A cutting device according to the present disclosure includes a main body, a fixed blade fixed to the main body, a movable blade capable of reciprocating in a slidable way with respect to the fixed blade, and a dial that is rotatably attached to the main body and is operated when a cutting height is adjusted. A rib which faces a clearance formed between the dial and the main body in a radial direction of the dial is formed in the main body.

Abstract: The present disclosure provides a cutting device capable of more reliably preventing an erroneous operation of a dial during use. The cutting device according to the present disclosure includes: a main body including a grip; and a blade part including a fixed blade fixed to the main body and a movable blade capable of reciprocating in a slidable way with respect to the fixed blade. Furthermore, the cutting device includes a dial that is rotatably attached to the main body and is operated when a cutting height is adjusted, and a cover that covers a part of the dial in a state where rotation of the dial is permitted. The dial is attached between the grip and the blade part to the main body, and the cover covers a grip side of the dial.

Abstract: The present disclosure provides a cutting device capable of further improving operability of a dial. A cutting device according to the present disclosure includes a main body, a fixed blade fixed to the main body, and a movable blade capable of reciprocating in a slidable way with respect to the fixed blade. Furthermore, the cutting device includes a cutting height adjustment mechanism that includes a dial rotatably attached to the main body and is capable of adjusting a cutting height by rotating the dial. The cutting height adjustment mechanism includes a holding mechanism capable of holding the dial in a stepwise manner, and the holding mechanism includes a recess and a protrusion part that are releasably engaged with each other. At least one of the recess and the protrusion part includes an irregularly-shaped engagement part having a different shape on one side and the other side in a rotation direction of the dial.
