The value is determined as shown in equations (1) to (4). Where I
Is the second moment of area, and J is the second moment of area.

Attempts to lower the spring constant of R1 and R2 around the X and Y axes
Then, it is necessary to lengthen the shaft length L. Increase the axial length L
And the torsional rigidity in the torsional direction P around the load transmitting direction Z is low.
Become. On the other hand, the translational spring constant (K X= KY, KZ)
When the axial length L becomes longer than the diameter d, the load transmission direction Z
The spring constant components in the X and Y directions are
It drops sharply. Also, apply a compressive load in the load transmission direction Z.
Buckling load (Euler load) in the case of beam is expressed by equation (5).
It is.

保できる。As described above, when the second fixing member 50 applies a force in the swinging directions R1 and R2 to the first fixing member 40, the first elastic member 60 ensures sufficient elasticity.
At this time, the first fixed base 73 is attached to the second elastic member 70.
External force is transmitted via the second fixing pedestals 75a and 75b. Since the second elastic member 70 has a plate shape,
Out-of-plane bending deformation occurs in the direction in which the surface is bent, so the rigidity is low, the bending can be relatively easily performed, and the elasticity can be secured.

ける変形は容易ではない。On the other hand, when a force in the twisting direction P and the shearing direction Q around the load transmitting direction Z is applied to the first fixing member 40 from the second fixing member 50, the first elastic member 60 is easily deformed. At this time, an external force is transmitted to the second elastic member 70 via the first fixed seats 73a and 73b and the second fixed seats 75a and 75b. Since the second annular member 70 is plate-shaped, the second annular member 70 is deformed in the plane, so that the rigidity is high, and the deformation in the plane is not easy.

方向Ｒ２の剛性は低い状態が維持される。Therefore, according to the combination of the first elastic member 60 and the second elastic member 70, the translational stiffness in the load transmitting direction hardly changes, the translational stiffness in the shearing direction Q in the XY directions increases, and the translational stiffness around the Z axis increases. The rigidity in the torsional direction P increases, and the rigidity in the swing direction R1 around the X axis and the rigidity in the swing direction R2 around the Y axis remains low.
