Claim Text:
1. A hinge structure of a storage container comprising: a storage box having an opening for putting goods in said storage box and taking goods out of said storage box; a lid adapted to close at least a part of said opening; a hinge shaft rotatably connecting said lid to said storage box so that said lid can open and close at least a part of said opening; a brake shaft having a rotational axis that is coaxial with said hinge shaft, and said brake shaft being adapted to rotate about said rotational axis together with said lid; a braking device comprising a brake plate to generate a stable friction force in cooperation with an end face of said brake shaft, so that said stable friction force provides said brake shaft with rotational resistance to retain said lid at any position where said lid stops rotating around said hinge shaft; wherein said storage box and said lid each have a bearing member that comprises a bearing portion to support said hinge shaft rotatably, a side surface of said bearing member of said lid being arranged to abut on a side surface of said bearing member of said storage box so as to open and close said lid smoothly, said lid having a connecting member with which said brake shaft is engaged so that said lid and said brake shaft integrally rotate around said rotational axis when said lid rotates around said hinge shaft, said storage box having another bearing member, a side surface of said connecting member of said lid being arranged to abut on a side surface of said another bearing member so as to open and close said lid smoothly; and wherein said braking device is arranged beside said end face of said brake shaft, said brake plate extending in a direction intersecting said rotational axis, said brake plate being arranged along said end face of said brake shaft and secured with respect to said storage box, said braking device further comprising a friction plate disposed between said brake plate and said end face of said brake plate, a support shaft integrally formed on said end face of said brake shaft projecting along said rotational axis with said friction plate and said brake plate engaged with said support shaft, a swaged portion formed at the end of said support shaft with a spring plate and a washer pressed between said swaged portion and said brake plate so that said friction plate is pressed against said end face and said brake plate.
