PURPOSE: To provide the frictionless supporting structure of a turning shaft not to be rotated by providing a pair of annular inner side and outer side hubs position-shifted in an axial direction respectively disposed on the inner side and outer side of the deflection element of a deflection structure in a shift supporting structure. CONSTITUTION: The deflection elements 30, 32 and 34 are respectively provided with center openings 36, 38 and 40 for receiving the shaft 12 in a pass-through state. The deflection element is stainless steel whose cross section is relatively thin and is formed by a rigid, elastic, flexible and freely deformable material provided with corrosion resistance for indicating compliance. The elements 30, 32 and 34 are integrated and stipulate a supporting point for making the shaft 12 able to be turned so as not to generate friction, that is a turning center point 14. Through the range of angle movement stipulated beforehand by the elements, side direction rigidity for generating inverse force opposing the turning movement of the shaft 12 is generated. The turning center point 14 is aligned symmetrically to the intermediate deflection element 34. |
