<P>PROBLEM TO BE SOLVED: To provide a locking mechanism for bending structures which can firmly engage two members with each other, and also, can disengage the engagement with a little force. <P>SOLUTION: For an internal box 10, a lock panel 16 is continuously connected with one end of the left side surface section 15. The lock panel 16 is bent at the boundary position (main folding line) between the left side surface section 15 and the lock panel 16. The main folding line is not placed at the central section in the front and rear direction (height direction) of the internal box 10, and a protrusion section 21 sandwiched by openings 16A and 16B from the top and the bottom is located at an area where the main folding line is not placed. When the lock panel 16 is bent at the main folding line, the protrusion section 21 protrudes outward and stands up. <P>COPYRIGHT: (C)2012,JPO&INPIT |
