面アール部の曲率半径を測定している。(Prior Art) For example, when manufacturing a mold, a radius measuring tool is used to measure the radius of curvature of the cross-sectional radius of the mold. As shown in Fig. 9, the conventional radius measurement tool is constructed of a plurality of measuring plates 5 each having a plurality of rounded shapes cut out with different radii of curvature. From among the plurality of measurement plates 5, select a measurement plate 5 that seems to have a radius-shaped notch 5a of a size commensurate with the cross-sectional radius of the mold to be measured, and The radius of curvature of the rounded section is measured by pressing the section 5a against the rounded section and repeating this operation several times.

の選択が一層面倒なものとなる。(Problem to be solved by the invention) However, since the conventional radius measurement tool described above has a large number of measurement plates, it takes a long time to select a measurement plate that matches the cross-sectional radius of the target mold. This requires a lot of effort and time, making it a very troublesome task. In addition, since the above-mentioned radius measurement tool can only perform intermittent measurement, the radius of curvature is 5.5 which cannot be covered by a measurement plate with a radius of curvature of 5.0 mm and a measurement plate with a radius of curvature of 6.0 mm. It is not possible to accurately measure the subtle differences in size for a cross-sectional radius of mm. In order to cover this as much as possible, the number of rounded notches of different sizes may be increased, but this increases the number of measurement plates and makes selection of the measurement plates even more troublesome.

対応している。(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. In Figs. 1 to 4, 1 is a measuring instrument main body formed in a disk shape, and the thickness dimension T of the measuring instrument main body 1 is , is set to gradually increase in the upward direction in FIG. A groove 2 is formed on the entire circumferential side surface of the measurement tool main body 1, and the inner surface of the groove 2 is formed in the cross-sectional rounded part (fifth
The cross section is formed into an arc shape so that the radius of curvature indicated by reference numeral 4) in the figure can be measured. The radius of curvature of the arc-shaped cross section increases as it goes in the circumferential direction of the measuring instrument main body 1.
The size is set to vary continuously. A scale 3 is provided along the outer peripheral edge of the measuring tool main body 1. The numerical value displayed on this scale 3 corresponds to the size of the radius of curvature of the arcuate cross section.

部４の曲率半径の大きさを正確に測定できる。 To explain the case of using the radius measurement tool having the above configuration, first, as shown in FIG. If there is a gap t (see Fig. 6) between the arcuate surface and the rounded section 4, by rotating the measuring instrument main body 1, the arcuate cross-sectional surface of the groove 2 in contact with the rounded section 4 can be adjusted. Change continuously. As a result, the cross-sectional rounded portion 4
The size of the radius of curvature of the cross-sectional arcuate surface that contacts the groove 2 matches that of the cross-sectional rounded portion 4, and as shown in FIGS. When the gap becomes zero, the measuring tool main body 7 is stopped. Next, by reading the numerical value on the scale 3 corresponding to the cross-sectional arcuate surface that contacts the cross-sectional radius portion 4 in this state, the size of the radius of curvature of the cross-sectional radius portion 4 can be accurately measured.
