Abstract:
PROBLEM TO BE SOLVED: To provide a portable cutting machine of which a protective cover can be easily fixed at a desired position.SOLUTION: A cutting blade 3 cuts an object to be cut by rotational action around a central axis thereof. A cutting machine body 2 rotatably supports the cutting blade 3. A protective cover 4, which partially covers the cutting blade 3, is so provided as to be rotatable around the central axis of the cutting blade 3. A pressing body 5 is moved to the protective cover 4 side so as to press a guide plate 44 onto a support plate 26, and maintains a state such that rotation of the protective cover 4 is regulated. A torsion coil spring 7 energizes the pressing body 5 to the protective cover 4 side. When the pressing body 5 is moved to an opposite side of the protective cover 4 against an energization force of the torsion coil spring 7, a rotation regulation state of the protective cover 4 is released.SELECTED DRAWING: Figure 7
