It is possible to detachably attach 1 and 12.

A support arm 21 is fixed to the support frame 5 such that a tip thereof is disposed above the support base 9, and a detection rod 22 a extends downward at the tip of the support arm 21. Push-pull gauge 2 as compression load detector
A glass plate 23 as a contact member is attached to the lower end of the detection rod 22a so as to face the soft object 11 on the support base 9. The push / pull gauge 22 includes the soft material 11 and the glass plate 2.
A linear gauge 24 is attached as a relative movement amount detector for continuously detecting the relative movement amount of the detector 3. A detector 24 a extending downward from the linear gauge 24 is attached to the fixing means 13 on the support 9, for example. It contacts the upper surface of the mounting portion 16.

In response to the close movement of the glass plate 23 and the soft material 11, the lip 11a of the soft material 11 first comes into resilient contact with the side surface of the glass plate 23, and then contacts the end of the glass plate 23. The elastic displacement portion 11b of the soft object 11 comes into contact. In addition, the glass plate 23 and the soft material 1
When the glass plate 23 is fitted to the soft object 12 by bringing the glass plates 23 close to each other, the lips 12a,
12 b comes into elastic contact with both surfaces of the glass plate 23.

Next, the operation of this embodiment will be described. In measuring the compressive load of the soft material 11, the lifting means 6, that is, the support base 9 is lowered and the fixing means 13 is used as shown in FIG. The soft object 11 is mounted on the support 9, and the support 9 is raised by the cylinder 7. Thereby, the soft object 11 mounted on the support 9
Is close to the glass plate 23 at the fixed position,

The movement amount is continuously detected. Therefore, it is possible to easily obtain the relative movement amount of the glass plate 23 and the soft material 11, that is, the bending amount of the soft material 11 and the compression load in a continuous correspondence.

In order to measure the sliding load between the soft object 12 and the glass plate 23, the soft object 11 is removed with the lifting plate 6, that is, the support base 9 being lowered, and then the fixing means as shown in FIG. The soft material 12 is mounted on the support base 9 by 13, and the support base 9 is raised by the cylinder 7.

During this relative sliding, the sliding load acting between the soft material 12 and the glass plate 23 is continuously detected by the load cell 26, and the glass plate 23 and the soft material 1 are detected by the linear gauge 27.
2 is continuously detected, so that the relative movement amount of the glass plate 23 and the soft object 12, that is, the sliding contact amount of the glass plate 23 and the soft object 12 and the sliding load continuously correspond. Can be easily obtained.
