Substrate storage container

A substrate storage container comprising:

• a lid that is fitted to an opening of a container body capable of storing a substrate;
• and
• a locking mechanism that locks the fitted lid,
• wherein:
• the lid comprises:
• a lid housing that is removably fitted to an open front face of the container body;
• and
• a front plate that covers a front face of the lid housing,
• wherein:
• the locking mechanism is disposed between the lid housing and the front plate, and
• a passage opening for the locking mechanism is disposed on a periphery of the lid housing so as to be opposite to a locking pocket on a front inner circumference of the container body,
• the locking mechanism comprises:
• an operating member that is supported on the lid and turned by an external operation;
• a slide member that slides as the operating member turns;
• and
• a bent locking member that is projected from the passage opening of the lid as the slide member slides and is configured to be engaged with the locking pocket on the front inner circumference of the container body,
• wherein:
• the bent locking member is rotatably connected to a distal part of the slide member by a resin shaft having a diameter of 1.5 mm or greater, and
• the bent locking member of the locking mechanism is configured to rotate in a thickness direction of the lid while a center of rotation of the bent locking member is arranged at a forepart on a front side of the bent locking member,
• the locking mechanism comprises a holder member that is fitted and assembled with the slide member and the bent locking member,
• the forepart on the front side of the bent locking member is rotatably supported on both sides of the holder member by means of a resin fulcrum shaft having a diameter of 1.5 mm or greater,
• the bent locking member and the holder member are formed to separate into respective two parts with respect to a width direction of the slide member, and
• the resin fulcrum shafts to be supported respectively by both side parts of the holder member are formed protruding from respective sides of the forepart on the front side of the bent locking member while resin shafts to be penetrated through the distal part of the slide member are supported on a rear side of the bent locking member.

• resin fulcrum shafts to be supported respectively by both side parts of the holder member are formed protruding from respective sides of the forepart on the front side of the bent locking member, and
• a plurality of joint pipes are formed near a bent portion on a rear side of the bent locking member while the resin shaft that penetrates through the distal part of the slide member is inserted into each of the joint pipe, whereby the holder member is configured to be separated with respect to a width direction of the slide member.
