• a lock mechanism for allowing locking and unlocking, provided on the other side of both the storage device body and the opening and closing member;
• wherein the lock mechanism comprises
• a lock member having an engaging surface at which the lock member can engage with or disengage from an accepting portion provided to the opening and closing member,
• an unlocking button capable of being pushed against the storage device body,
• a cam mechanism adapted to disengage the lock member from the accepting portion by a push of the unlocking button 17,
• a biasing member for constantly biasing the lock member toward a locking direction,
• wherein the lock member behaves as a pivotable member pivotable about a lock pivot shaft, and
• wherein the engaging surface of the lock member and the accepting portion of the opening and closing member form a plane perpendicular to an opening direction toward which the opening and closing member under a closed state can open about the opening/closing center axis portion.
