    Abstract: An elliptical coned disc spring can be accommodated in a rectangular installation space, can yield non-linear load characteristics, and can reduce stress differences between a bending part at a long radial part side and a bending part at a short radial part side. An elliptical coned disc spring has a body in which an outer circumference is an ellipse in a disc shape. A hole is formed at the center of the body. The hole may have various shapes such as a circle, an ellipse, etc. The body has a long radial part 111 and a short radial part. A plate width of the long radial part is set to be greater than a plate width of the short radial part (that is, a>b).

    Abstract: A pressing structure is arranged between a first pressed body and a second pressed body opposite to the first pressed body and presses the first pressed body and second pressed body. The pressing structure includes a spring member including: a base portion formed of a single strip-like member and having a curved principal surface; two extended portions extending respectively from end portions of the base portion and curved in a form inverse of a curving form of the base portion; and two bent portions extending respectively from end portions of the two extended portions, the end portions being at sides opposite to sides connected to the base portion, the two bent portions being curved in a form inverse of the curving form of the extended portions; and the maximum thickness of the extended portions and bent portions is smaller than the maximum thickness of the base portion.

    Abstract: A deformation absorption member for a fuel-cell-stack disposed between an anode side separator and a cathode side separator. The deformation absorption member includes a thin-board-like base material, and a plurality of raised pieces in which extension portions extended from proximal ends are arranged in a grid pattern. Each raised piece of the plurality of raised pieces is formed in a non-rectangular shape in which the width of the extension portion is shorter than the width of the proximal end, and plurality of raised pieces are configured so that the directions of the extension portions of mutually adjacent raised pieces are alternately arranged, and positions of the proximal ends of the mutually adjacent raised pieces are arranged in at least overlapping positions.
