    Abstract: A suspension device for solving problems that occur in a conventional damper and a rubber member is provided. A suspension device 101 is equipped with, for example, a damper 50 including a piston portion 51, a suspension spring 60, an upper seat 70, and a spring 1. The spring 1 is arranged between an upper end portion of the piston portion 51 and a lower surface of the upper seat 70 and is an elastic member for receiving a load from the damper 50. The spring 1 has load characteristics in which hysteresis does not occur, whereby a dynamic spring constant can be small. Therefore, transmission of vibrations in a high-frequency range and an infinitesimal amplitude range is decreased. On the other hand, the spring 1 has a main body 10 that functions as a disc spring portion. Therefore, the spring constant in a direction perpendicular to an axis line of the damper 50 is large, whereby stiffness in the direction perpendicular to the axis line is increased. As a result, ride quality is improved, and stable handling is obtained.

    Abstract: The first corner portion 13, which is formed at the boundary portion between the main body portion 10 and the first cylindrical portion 11 which are positioned to each other as shown in Figs. 2A and 2B , can elastically deform in application of load such that the angle α of the first corner portion 13 changes depending on the pressing force from the first member 101. In this case, the first corner portion 13 can move toward the outside of the inner periphery portion of the main body portion 10 (the left side in the Figure) while the angle α changes. The second corner portion 14, which is formed at the boundary portion between the main body portion 10 and the second cylindrical portion 12 which are positioned to each other as shown in Figs. 2A and 2B , has the same function as that of the first corner portion 13, and it can move toward the outside of the outer periphery portion of the main body portion 10 (the right side in the Figure) while the angle β changes depending on the pressing force from the second member 102 in the elastic deformation of the second corner portion 14. As a result, the spring can prevent generation of hysteresis in load characteristics without increasing the number of parts, and enables height adjustment of the spring.

    Abstract: [Object] To provide an attachment structure for a deformation absorption member that is capable of preventing the proximal end from being lifted up as well as preventing the proximal end from being subjected to excessive plastic deformation, even if a load is applied to a raised piece of the deformation absorption member.
    [Solution] The attachment structure for a deformation absorption member 20 is an attachment structure for a deformation absorption member that is used disposed between an anode side separator 11 and a cathode side separator 12. The deformation absorption member comprises the raised pieces 22 and the joint portions 23. The raised pieces 22 are provided raised from one surface 21a of a base material 21 in a grid pattern, and the extension portions which are extended from the proximal ends are abutted to a cathode side separator 12. The joint portion 23 is formed by partially joining a location between, from among a plurality of raised pieces, the proximal end of one raised piece 22M, and the proximal end of another raised piece 22N which is adjacent in another direction Z that intersects a one direction Y taken along from the proximal end of the one raised piece to the extension portion side, to the anode side separator 11 or the cathode side separator 12.
