NOVELTY - The support structure includes a housing (2); a circular opening (61) formed in the housing in which the electroosmotic member (3) is disposed; a space formed in the housing around the opening; and an elastic piece (63) to separate the opening and the space from each other, and to support the electroosmotic member. A cushion is filled in a gap between a wall of the opening and an edge of the electroosmotic member.    USE - Support structure of a thin plate-like electroosmotic member of an electroosmosis pump used for an electric power generation apparatus for electronic equipment (all claimed).    ADVANTAGE - The attenuation chamber functions as a damper which releases a stress of the elastic piece, therefore, impact and vibration can be absorbed, and the electroosmotic member can be prevented from being damaged. A load is equally dispersed and absorbed by the elastic pieces and the attenuation chamber; therefore, shock absorption effect can be enhanced. The electroosmotic member is supported by the cushioning, therefore, when the electroosmotic member receives vibration or impact in the circumferential direction or radial direction, the cushioning is deformed and thus, a large load is not applied to the electroosmotic member. The elastic projections are deformed in the gap between the edge of the electroosmotic member and the wall of the opening when impact or vibration are applied, reducing a load to be applied to the electroosmotic member. Electric energy is stably supplied to the electronic equipment body.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) an electroosmosis pump mounted in an electric power generation apparatus having a fuel cell;    (2) an electric power generation apparatus; and    (3) an electronic equipment    DESCRIPTION OF DRAWING(S) - The drawing shows the exploded perspective view of an electroosmosis pump.
