Claim 7:
8. A pressure control valve structure used for a power storage module having a plurality of internal spaces, the pressure control valve structure comprising:
a bottom wall portion having a plurality of communication holes communicating with their associated internal spaces;
a plurality of projections, each in a circular shape, protruding outwardly from an inner wall surface of the bottom wall portion so as to surround their associated communication holes;
a plurality of elastic valve bodies, each of the elastic valve bodies closing their associated communication holes and in contact with the plurality of projections;
an outer peripheral wall portion protruding from the inner wall surface so as to surround the plurality of projections collectively;
a plurality of connecting projections each having a lattice-frame shape are formed in an outer wall surface of the bottom wall portion, and are spaced apart from each other in a direction in which the valve bodies are arranged so that a spaced portion is provided between connecting projections in the direction in which the valve bodies are arranged; and
a cover made of a resin and fixed to the outer peripheral wall portion, the cover having a flat inner surface that presses the elastic valve bodies so as to compress the elastic valve bodies towards their associated projections,
wherein the cover has a discharge port through which gas in the pressure control valve structure is discharged to an outside of the pressure control valve structure, the discharge port being formed in an outer surface of the cover so as to face a location where the spaced portion is provided.
