Claims

[Claims for Utility Model Registration] Consisting of a shell having an approximately spherical hollow chamber, and a diaphragm fixed to the shell and partitioning the hollow chamber of the shell into a gas chamber and a liquid chamber, the diaphragm having an elastic layer. and a plurality of metal thin films disposed on the exposed surface or inside of the elastic layer at intervals of 1 mm or more, the hard-to-deform part having the metal thin films, and the part on which the metal thin films are not disposed. 1. A bladder type accumulator comprising an easily deformable portion consisting only of an elastic layer.
