First, the total length "A" of the screw plug gauge 4 having the passing screw 41 and the blind screw 42 is measured with a caliper or the like, and the female screw 51 of the product 5 is fitted with the passing screw 41 of the screw plug gauge 4. After the insertion, the length "B" of the protruding portion of the screw plug gauge 4 was measured with a caliper or the like, and the depth of the effective diameter was calculated from the difference "AB". Further, it may be calculated by the rotation speed of the screw plug gauge 4. Such a method is troublesome and sometimes makes a mistake in calculation. Further, in the case of calculating the number of rotations, the error due to the individual was also large.

FIG. 2 is a diagram for explaining the operation of the apparatus shown in FIG. In the figure, 30 is a product, and 31 is a female screw of the product 30.
If the blind side screw 22 is inserted into the female screw 31 to be inspected while rotating and does not enter the female screw 31, the female screw 31 is within the allowable range of the effective diameter. It is bad. Then, with respect to the female screw 31 within the allowable range, the passage side screw 21 is inserted into the female screw 31 while rotating, and when it is inserted, the insertion is continued as it is within the allowable range. During this time, the gauge member 2 is in the through hole 1 of the case 1.
It moves through the inside of 1 in the direction of the side screw 21. Street side screw 2
When 1 does not fit into the female screw 31, the scale of the scale portion 23 located at the end of the case 1 is read. This allows
The depth "H" of the effective diameter of the female screw 31 is known. When the passing side screw 21 does not enter the female screw 31, the female screw 31 is regarded as too small and is regarded as defective.

構成も本発明に含まれる。FIG. 4 shows a case where the position where the female screw 36 is applied in the product 35 is higher than the other surface and the circumference of the female screw 36 is surrounded. Of the effective diameter from the normal surface is measured. In this case, the numerical value of the scale of the scale portion 23 is different from that of the device of FIG. In this way, the depth of the effective diameter of the female screw of various objects can be measured by changing the probe. The present invention also includes a configuration that does not include the tracing stylus 14 to 16.

With the through hole 24 and the straight pin 25, the case 1
The gauge member 2 is prevented from coming off from the casing and the gauge member 2 is prevented from rotating with respect to the case 1. However, a configuration may be adopted in which the gauge member 2 is provided with a convex portion, a groove portion is provided in a part of the through hole 11 of the case 1 in the longitudinal direction, and the convex portion of the gauge member 2 is movably positioned in this groove portion. In this case, the case 1 can be realized by forming the case 1 from plastic or the like and providing the convex portion of the gauge member 2 with a spring inside so that the convex portion can be retracted into the gauge member 2.

However, with the gauge member 2 alone, the effective diameter of the female screw is within an allowable range. It may be configured such that the case 1 is fitted to the gauge member 2 and the scale of the scale portion 23 is read when the passage side screw 21 is rotated by inserting into the female screw and stopped.
