[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention (how to implement the invention) will be briefly described with reference to the drawings, showing the operational effects thereof.

According to the present invention, the base 3 is erected between the opposing measurement surfaces 1 and 2 so that the contact portion 4 is in contact with one of the measurement surfaces 1 and the other is in contact with the other measurement surface 2. When the contact portion 5 is brought into contact, the distance between the measurement surfaces 1 and 2 or the difference between the distance between the measurement surfaces 1 and 2 and the standard distance can be measured by the measurement means 10 provided on the base 3.

According to the present invention, the abutting portions 4 and 5 provided on the base 3 are not formed into a flat surface which comes into contact with the measuring surfaces 1 and 2 but are formed into a curved shape having an outwardly convex contact with a point or a line. Is formed.

This configuration contributes to simple and quick high-precision measurement work when measuring the distance between the opposing measurement surfaces 1 and 2.

More specifically, this measuring operation will be described by taking as an example a case where the distance between the right and left rails of a railway line is measured. First, in this measuring operation, the contact portion 4 is attached to one of the measurement surfaces 1. The contact portion 5 is brought into contact with the other measurement surface 2 by shaking the base 3 several times with the contact portion 4 as a fulcrum (by sliding horizontally), and provided on the base 3. The measuring means 10 measures the distance between the measurement surfaces 1 and 2 or measures the difference between the distance between the measurement surfaces 1 and 2 and the standard distance. The measuring means 10 measures the shortest distance between the measurement surfaces 1 and 2, thereby measuring the distance between the measurement surfaces 1 and 2, or measuring the difference between the distance between the measurement surfaces 1 and 2 and the standard distance. I have.

Therefore, if the contact portions of the contact portions 4 and 5 to be brought into contact with the measurement surfaces 1 and 2 are flat surfaces, the measurement surfaces 1 and 2 and the contact portions 4 and 5 are completely contacted. The shortest distance between the measurement surfaces 1 and 2 can be measured by bringing the substrates 3 into contact (a state in which the base 3 is perpendicular to the measurement surfaces 1 and 2). In this case, the base 3 is shaken. When the contact portion 4 on the fulcrum side is a flat surface, it does not function as a good fulcrum, that is, it comes into contact with the measurement surface 1 at an angle and floats, or , 2 and the contact portions 4, 5 are in surface contact, and are susceptible to the surface condition (subtle irregularities) of the measurement surface 1 due to a large contact area, which causes a problem that a measurement error is slightly generated.

Further, even when the contact portion of the contact portion 5 to be brought into contact with the other measurement surface 2 is a flat surface, the measurement surface 2
And the influence of the surface condition of the measurement surface 2 causes the same problem as described above.
In addition, while high-precision work is required for this measurement work, due to the nature of the work of measuring long rails, quick work is required, and if the work is performed carefully, work efficiency decreases, Nevertheless, this is a vicious cycle, as the quicker the work, the more noticeable this measurement error becomes.

In this respect, according to the present invention, the abutting portions 4 and 5 are not formed into a flat surface in contact with the measuring surfaces 1 and 2, but are formed into an outwardly convex curved shape in contact with a point or a line. Therefore, unlike the case described above, the contact portions 4, 5 are always
Can be brought into good contact with the measurement surfaces 1 and 2,
That is, for example, even in the operation of shaking the base 3 by bringing the contact portion 4 into contact with the one measurement surface 1, since the contact portion 4 comes into contact with the measurement surface 1 at a point or a line, the contact point 4 serves as a fulcrum. It is easy to function satisfactorily, and since the contact area of the contact portions 4 and 5 with the measurement surfaces 1 and 2 is small, it is hard to be affected by the state of the measurement surfaces 1 and 2 and thus a measurement error occurs. Can be prevented as much as possible.

Therefore, a highly accurate measurement operation can be performed, and the operator can perform the measurement operation with ease, and this highly accurate measurement operation can be performed easily and quickly.
