Claims

[Scope of Claim for Utility Model Registration] (1) A cover that closes an opening through which another component is inserted into the case when no other component is inserted, including a closing portion that closes the opening and both ends of this closing portion. The bearings are rotatably fixed to shafts protruding from opposing inner wall surfaces inside the case, so that the opening is closed and the inner wall surface of the case is fixed. The housing is rotated inward to the inside of the case until it comes into contact with a rotation stopper formed in the case, and while the rotation stopper is rotated to the rotation stop position, another member is inserted through the opening through the space surrounded by the closing part and the bearing part. A cover structure characterized by: (2) Utility model registration claim 1, which comprises a return means for rotating and biasing the opening so as to close it.
Cover structure as described in section.
