    Abstract: A clutch apparatus is equipped with two clutch structures having a clutch drum therein. A driven plate and a piston are provided in the clutch drum of each clutch structure, and a primary coned disc spring and a secondary coned disc spring, which are ring-shaped, are provided between the driven plate and the piston. A flat portion 12 is formed on an inner peripheral portion of a convex surface of the primary coned disc spring 1, and the flat portion 12 can come into contact with a counter member first when a load is applied. A load in a flat condition due to elastic deformation is adjusted by the flat portion so as to be a desirable value. Blanks 1A and 2A of the primary coned disc spring and the secondary coned disc spring can be obtained from one sheet of material having the same thickness. In this case, the flat portion 12A is formed by press forming on an inner peripheral portion of the blank 1A in view of the shape thereof after bending forming is performed.

    Abstract: [Problem] To provide a fuel-cell-stack manufacturing method capable of increasing the load that a raised piece of a deformation absorption member can receive from the separator unit.
    [Solution] The deformation absorption member 20 used in the fuel-cell-stack 1 manufacturing method is disposed between an anode side separator 11 and a cathode side separator 12, and comprises a thin-board-like base material 21, and a plurality of raised pieces 22 that are provided raised from one surface 21a of the base material in a grid pattern. In the arrangement step, an extension portion (the free end portion 22b) extended from the proximal end (the fixed end portion 22a) of the raised piece provided on one surface of the base material is disposed so as to be abutted to the cathode side separator or the anode side separator. The setting step sets the interval between the anode side separator and the cathode side separator along the lamination direction X so that the deformation of the raised piece exceeds an elastic deformation region and enters a plastic deformation region, and is also in a region in which the proximal end that is moved due to the deformation will not come in contact with the cathode side separator or the anode side separator.

    [Solution] The deformation absorption member 20 is used disposed between an anode side separator 11 and a cathode side separator 12. The deformation absorption member is made of a thin-board-like base material 21, and comprises a plurality of raised pieces 22 in which the extension portions extended from the proximal ends are arranged in a grid pattern. The raised piece 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 is configured so that the directions of the extension portions of mutually adjacent raised pieces are alternately arranged, and the positions of the proximal ends of the mutually adjacent raised pieces are arranged in at least overlapping positions.
