<P>PROBLEM TO BE SOLVED: To provide a washer which materializes the even surface contact in a washer surface and is not deformed because of inclination or deviation of the washer itself thereby exhibiting the even axial force buffering action around the axis. <P>SOLUTION: The axial force buffering washer into which a bolt shaft S is inserted, is sandwiched and fixed between respective opposite surfaces of two screwed bodies O which are screwed with the bolt shaft S, wherein the sandwiched cross-section element 1 of a prescribed shape having a hollow part 2 is annularly connected around the bolt shaft S as an object to be attached to form a tube-like or coil-like ring body as a whole. On any phase around the bolt shaft S, a contour shape of the sandwiched cross-section element 1 and a cross-section area of the hollow part 2 are formed equally. Such an axial force buffering washer is sandwiched such that an equal resilient repulsive force is applied to the bolt shaft S direction in the bolt shaft cross-section because the prescribed shape of the sandwiched cross-section element is crushed and deformed in the fixed state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
