ストを低減させることができる。For example, as shown in FIG. 4, a groove 16 formed in the large diameter portion 13 of the fixed shaft 2 described above is provided with a guide portion 16a extending in the thrust direction of the large diameter portion 13 and a screw measuring tool. The guide portion 16a located on the other end side has a locking portion 16b which is formed continuously and bends in the radial direction, and the locking portion 16b has a small screw protruding into the holder 17. By locking the locking convex portion 18 of 18, the movement of the holder 17 at the reference position toward the one end side of the screw measuring tool may be restricted. In such a configuration, the holder 1 is rotated by screwing the screw gauge 14 into the screw hole H and then rotating the holder 17.
7 can be moved to the work W side. Moreover, since the operation can be performed with one hand, the same effect as that described above can be obtained. Further, since the coil spring 20 can be eliminated, the number of parts of the screw measuring tool can be reduced and the manufacturing cost can be reduced.

While the permanent magnet 25 is externally fitted to the end portion of the operating portion 3 of the housing 1, the holder 17 is made of a material that can be magnetically attached in advance, and the permanent magnet 25 is magnetically attached to the holder 17 to form a reference. It may be configured to restrict the movement of the holder 17 in the position to one end side of the screw measuring tool.
Even in such a configuration, the holder 17 can be moved to the work W side with one hand by the same operation as that shown in FIGS. In that case, in addition to the coil spring 20,
As shown in FIG. 5, the small screw 18 can be omitted, and it is not necessary to form the groove 16 shown in FIGS. 1 and 4 in the large diameter portion 13 of the fixed shaft 2. Therefore, the same effect as that shown in FIGS. 1 to 3 can be obtained, and the manufacturing cost can be reduced more than that shown in FIG.
