For example, there is one disclosed in JP-A-6-71603. In this conventional stopper device, as shown in FIG. 9, which employs FIG. 11 of the publication, an arm 85 is turned on side surfaces of a base end portion 68 of a circular saw main body 4 via support portions 80, 80 and a support shaft. The adjusting bolt 84 is mounted movably on the tip end of the rotation of the arm 85, and the adjusting bolt 84 is brought into contact with the bracket 71 that tilts and supports the circular saw body 4 via the support shaft 69. The configuration was such that a projection 87 was provided.

制されない。According to this configuration, if the arm 85 is rotated to the first position where the adjustment bolt 84 is located on the tilting fulcrum side (the support shaft 69 side) of the circular saw main body 4, the circular saw main body 4 is lowered. When tilted, the tip of the adjustment bolt 84 is
, Thereby restricting the lower limit position of the circular saw main body 4. This lower limit position corresponds to the arm 8 of the adjustment bolt 84.
It can be set arbitrarily by adjusting the screwing amount with respect to 5. Conversely, the arm 85 is
When the circular saw body 4 is rotated to the position, when the circular saw body 4 is tilted downward, the adjustment bolt 84 does not come into contact with the locking projection 87, so that the lower limit of the circular saw body 4 is not restricted by the stopper device. .

いる。Aside from the stopper device, a stopper bolt 78 is attached to the base end 68 of the circular saw main body 4, and a stopper 79 to which the stopper bolt 78 abuts is provided on the bracket 71. This also limits the lowering limit of the circular saw body 4,
The lowering limit regulated by the stopper bolt 78 is a fixed one determined by the positional relationship between the saw blade and the blade plate (hereinafter, referred to as the lowest lowering limit), and the stopper device is provided separately from the stopper mechanism. Thus, the lowering limit is set above the lowermost lowering limit, so that various forms of cutting operations such as grooving can be conveniently performed.

In addition, a positioning protrusion 25b for holding the lower limit switching member 25 at the lower limit releasing position or the lower limit regulating position is formed.
The relief concave portion 25a is formed to have a diameter (width) into which the protruding portion 24b can be inserted by being cut from the upper end edge in the drawing. The positioning projection 25b is formed by denting the upper surface of the lower limit switching member 25 and locally deforming in the thickness direction, and slightly protrudes toward the pedestal portion 24 (lower surface side).

下降限に規制される。According to the stopper device 20 of this embodiment configured as described above, when the lower limit switching member 25 is located at the lower limit release position as shown in FIG. 24c, whereby the lower limit switching member 25 is held at the lower limit release position. In a state where the lower limit switching member 25 is held at the lower limit releasing position, the lower limit switching member 25 is not located below the lower limit regulating bolt 22, so that when the circular saw main body 4 is moved downward as shown in FIG. The lower limit regulating bolt 22 passes by the side without contacting the lower limit switching member 25. In this case, since the fixing bolt 23 abuts on the projection 24b as shown in the figure, the lower limit of the circular saw main body 4 is restricted to the lowermost limit.

The restriction position is maintained.
In the state where the lower limit switching member 25 is located at the lower limit regulating position, the lower limit switching member 25 is located below the lower limit regulating bolt 22, so that the circular saw main body 4 is moved down to a certain position as shown in FIG. Then, the lower limit regulating bolt 22 abuts against the lower limit switching member 25, whereby the lower limit of the circular saw body 4 is restricted to be higher than the lowermost limit. In this case, as shown in the figure, the fixing bolt 23 floats from the upper surface of the projection 24b and thus from the upper surface of the lower limit switching member 25.

What is necessary is just to push the front-end | tip with a finger | toe and to rotate only a fixed angle. Due to the turning operation force, the lower limit switching member 25 can be turned by the positioning projection 25b coming out of the first concave portion 24c or the second concave portion 24d while slightly bending in the direction of floating from the pedestal portion 24. After the position change, the positioning protrusion 25b is again moved to the first or second concave portion 24c, 24.
By fitting into d, the lower limit switching member 25 is held in position.

According to 0, instead of moving the lower limit regulating bolt 22 provided on the circular saw main body 4, the lower limit switching member 25 provided on the table side (arm 8) supporting the circular saw main body 4 is moved. Since the configuration is such that the stopper device 20 is switched between valid and invalid, it is not necessary to secure a space for moving the arm 85 at the base end portion 4a of the circular saw main body 4 as in the related art. Even if there is, the stopper device 20 can be easily applied.

る。FIG. 6 is a partially cutaway side view of the stopper device. This figure shows that as a result of lowering the circular saw main body in a state where the lower limit switching member is located at the lower limit releasing position (the state of FIG. 4A), the lower limit regulating member passes without contacting the lower limit switching member. And the state in which the fixing bolt 23 is in contact with the projection 24b, that is, the state in which the circular saw main body is lowered to the lowermost limit.
