<p>A lid mounting structure for a pressure vessel for preventing a lid member (2) crimped to a curled portion (6) of an opening (5) of a vessel body (1) from being blown away by an abnormal rise of the internal pressure. A cut-away portion (8) or a through hole is formed in an outside wall of the curled portion (6), thereby locally reducing the elastic deformation resisting strength of the curled portion (6) with respect to expansion of the inside diameter of the opening to a level lower than that of the elastic deformation resisting strength of the lid member (2) in the inward radial direction.</p> |
