The floor panel 3 is placed and fixed on the upper surface of the upper protrusion 12 of the vehicle, and the load applied downward to the floor panel 3 and the floor support member 4 is supported by the vibration isolator 6, that is, the floor panel 3 is supported by the vibration isolator 6. 3 is vibration-proofed and supported. The vibration isolator 6 is compressed and deformed in proportion to the magnitude of the load applied to the floor panel 3.

る。At this time, since the load applied to the floor panel 3 is small, the distance between the upper surface of the upper protruding portion 12 of the floor receiving member 4 and the upper surface of the flange piece 11 of the frame 8 is larger than that of the vibration insulating material 6. When the amount of compressive deformation is small, the depressed floor panel 3 is positioned above the upper surface of the flange piece 11, and the load applied to the floor panel 3 is supported only by the vibration isolator 6. On the other hand, the load applied to the floor panel 3 is large, and the amount of compressive deformation of the vibration isolator 6 is larger than the distance between the upper surface of the upper projection 12 of the floor receiving member 4 and the upper surface of the flange piece 11 of the frame body 8. If it is large, the submerged floor panel 3 has flange pieces 11
The upper surface of the flange piece 11 bears the load applied to the floor panel 3 (FIG. 4).
As described above, in the support leg 1 of this example, the floor panel 3 is normally supported by the vibration isolator 6, but a load of a predetermined amount or more, that is, the upper surface of the upper protrusion 12 of the floor support 4 and the frame body 8 are supported. When the floor panel 3 is subjected to a load (overload) larger than the distance between the upper surface of the flange piece 11 and the vibration damping material 6, the floor panel 3 is covered by the upper surface of the flange piece 11 of the frame body 8. Are supported. Thus, the upper surface of the flange piece 11 of the frame body 8 constitutes the overload receiving portion 7 that receives the floor panel 3 when the vibration isolator 6 is compressed and deformed by a predetermined amount or more due to the overload applied to the floor panel 3. Of.

った利点もあるのである。As described above, when the floor panel 3 is subjected to an overload that causes the vibration isolator 6 to be compressed and deformed by a predetermined amount or more, the vibration isolator 6 is lowered by a predetermined amount of compressive deformation. If the floor panel 3 is received by the overload receiving portion 7, there is an advantage that the floor panel 3 is prevented from being excessively depressed. At this time, since the floor panel 3 is elastically contacted by the vibration isolator 6 via the floor support member 4, the vibration and soundproof effect of the floor panel 3 by the vibration isolator 6 can be continuously maintained. There is also an advantage. Further, as described above, when the floor panel 3 is overloaded, the floor panel 3 is supported by the overload receiving portion 7, so that the vibration isolator 6 is not compressed and deformed by a predetermined amount or more. That is, there is an advantage that excessive compression deformation is not performed, and the vibration damping material 6 is prevented from settling.

いるといった利点がある。When the vibration-proof material 6 that has been compressed and deformed elastically returns, the floor panel 3 and the floor support material 4 are lifted upward. For example, like the support leg 1 shown in FIG. 5, the support leg 1 in which the cushioning material 14 is not installed between the lower surface of the flange piece 11 of the frame body 8 and the cushioning material mounting portion 13 of the floor receiving material 4 which face each other. In this case, when the vibration-damping material 6 that is compressed and deformed elastically returns, the lower surface of the flange piece 11 and the cushioning material mounting portion 13 of the floor receiving material 4 collide with each other with an impact, and The collision may cause breakage of the support leg 1 or generation of collision noise. However, in the support leg 1 of this example, as described above, the cushioning material 14 is interposed between the lower surface of the flange piece 11 of the frame body 8 and the cushioning material mounting portion 13 of the floor receiving material 4 facing each other. Therefore, the shock-absorbing material 14 softens the collision between the lower surface of the flange piece 11 of the frame 8 and the shock-absorbing material mounting portion 13 of the floor receiving material 4, and the damage of the support leg 1 caused by the collision or There is an advantage that the generation of collision noise is prevented.

This example is an example in which the shape of the upper protrusion 12 of the floor receiving member 4 in the example of the previous embodiment is changed. That is, in the upper protrusion 12 of this example, the flange protrusion 2 that extends horizontally in the upper end portion of the upper protrusion 12 is arranged so as to increase the area of the upper surface portion on which the floor panel 3 is placed and fixed.
2 is formed. By providing the flange protrusions 22 on the upper protrusions 12 in this way, the mounting area of the floor panel 3 can be made wider, and the stability of the mounting and fixing of the floor panel 3 on the support legs 1 can be improved. It is being done.
In addition, in the support leg 1 of the present example in which the flange projection 22 is provided on the upper projection 12 of the floor receiving member 4, the flange projection is formed on the overload receiving portion 7 formed by the upper surface of the flange piece 11 of the frame body 8. The lower surfaces of 22 are opposed to each other. This allows
When the floor panel 3 is overloaded more than a predetermined amount, the overload receiving portion 7 can support the lower surface of the flange protrusion 22 of the floor receiving member 4, and the floor panel 3 can be prevented from sinking more than a certain amount. At the same time, excessive compression deformation of the vibration isolator 6 is prevented to prevent the vibration isolator 6 from settling.

In this example, a plurality of receiving protrusions 15 having different heights are provided on the upper surface of the vibration isolator 6 that receives the floor receiving member 4. That is, in the vibration-proof material 6 provided with the plurality of receiving projections 15 having different heights, the number of the receiving projections 15 that receive the floor receiving material 4 varies depending on the magnitude of the load applied to the floor panel 3. The floor support 4 can be received by changing the contact area. According to this, when the load applied to the floor panel 3 is small, the vibration-proof material 6 supports the floor receiving material 4 with a soft elastic force,
Therefore, it is possible to improve the light impact sound absorbing effect. When the load applied to the floor panel 3 is large,
Since the vibration isolator 6 gradually supports the floor receiving member 4 with a strong elastic force, it is possible to suppress the sinking of the floor panel 3.
