For example, the vehicle weight of the truck is directly transmitted from the upper surface plate 4 to the pressure receiving portion 2 via the rod-shaped projection 5. On the other hand, for example, with respect to the relative horizontal movement between the upper plate 4 and the pressure receiving portion 2 due to an external force in the horizontal direction on the upper plate 4, the rod-shaped protrusion 5 when the bar-shaped protrusion 5 horizontally moves relative to the external force. Is effectively absorbed by the expansion and compression deformation of the elastic body 6 surrounding the. Therefore, the horizontal external force generated by the loading of the truck on the upper surface plate 4, the stop of the braking of the truck on the upper surface plate, etc. is effectively absorbed without breaking the beam portion 3 which constitutes the flexure element of the device. To be done. Further, relative tilting of the upper surface plate 4 and the pressure receiving portion 2 is effectively absorbed by the shearing, stretching and compressive deformation of the elastic body 6.

Since the relative movement of 5 is restricted in the recess 8, the tip end portion of the rod-shaped projection 5 abuts against the inner peripheral surface of the recess 8 and is stopped, and the top plate 4 and the pressure receiving portion 2 are separated. Can be prevented. As described above, in the load measuring device configured as described above, since the vertical load is supported by bringing the tip of the rod-shaped projection 5 into contact with the bottom surface of the concave portion 8, the elastic body 6 can be set to a relatively small spring constant and a large spring constant can be obtained. Even if vertical load is allowed, it is possible to secure a sufficient amount of deformation in the horizontal direction and tilting direction. Further, as in the conventional example of FIG. 8, when the load measuring devices are arranged at the four corners of the load receiving plate, the rod-shaped projections 5
The height error due to the load measuring device at the four corners can be increased by opening a gap without contacting the tip of the base and the bottom surface of the concave portion 8 or by allowing a slight displacement in the vertical direction through a rubber in the gap. Can also be absorbed.

The cylindrical elastic body 6a sandwiched between the inner peripheral surface of the above and the side surface of the rod-shaped projection 5 has a cylinder length in which it contacts the lower surface of the upper surface plate 4 from the bottom surface of the concave portion 8. Therefore, in this configuration,
Among the relative horizontal movements and relative tilts of the upper surface plate 4 and the pressure receiving portion 2, especially for the input in the relative tilting direction, the buffering effect by the deformation of the elastic body 6a becomes higher.

Therefore, with respect to the input of the relative horizontal movement and the relative tilting direction, the cushioning effect by the deformation of the elastic body is further enhanced.

In the example shown in FIG. 5, the pressure receiving portion 2 has a through hole 10 penetrating from the upper surface plate 4 side to the installation surface 9 side.
However, the small diameter portion 10a is on the top plate side and the large diameter portion 10b is on the installation surface side.
It is formed so that it becomes. A rod-shaped projection 11 is inserted into the through hole 10, and a pressing member 12 having an outer diameter larger than the inner diameter of the small diameter portion 10a of the through hole 10 and smaller than that of the large diameter portion 10b is screwed to the tip portion thereof. . Further, the tip of the pressing member 12 has a spherical shape. An internal thread is formed on the inner peripheral surface of the opening of the through hole 10 on the installation surface side, and the upper surface of the bottom lid 13 is screwed and closed so as to come into contact with the tip of the pressing member 12. Therefore,
In this configuration, relative horizontal movement and relative tilting of the top plate 4 and the pressure receiving portion 2 are allowed. Also, the load applied to the top plate 4 can be detected with a strain gauge without loss,
The movement of the upper plate 4 in the axial direction of the rod-shaped projection 11 in the direction of separating from the pressure receiving portion 2 is prevented by the pressing member 12 hitting the step portion of the inner peripheral surface of the through hole.

In a load measuring device for detecting a load applied to a pressure receiving portion by a gauge as a strain amount at a portion of a beam portion, an upper surface plate is opposed to the pressure receiving portion at a distance, and the upper surface plate faces the pressure receiving portion. A bar-shaped projection is formed on the surface toward the pressure-receiving portion, and a recess for accommodating the tip of the bar-shaped projection is formed in the pressure-receiving portion, and the rod-shaped projection and the pressure-receiving portion are supported by an elastic body packed in the recess. Load measuring device characterized by being connected.
