い。In order to attach the lid to the box body via the connecting member, first, for example, the third hinge forming portion of the connecting member is inserted into the recess of the first hinge forming portion on the box body side from one end of the connecting member. It may be fitted while sliding, and then the fourth hinge forming part of the connecting member may be inserted into the concave part of the second hinge forming part on the lid side while sliding the lid side. Of course, the third hinge constituent part and the fourth hinge constituent part of the connecting member are provided in the concave part of the first hinge forming part on the box body side and the concave part of the second hinge forming part on the lid side. It may be fitted at the same time while sliding it from one end of the above. Alternatively, first, the fourth hinge forming part of the connecting member may be slid on the connecting member side in the recess of the second hinge forming part on the lid side. After the insertion, the third hinge forming part of the connecting member may be fitted into the recess of the first hinge forming part on the box body side while sliding the connecting member side.

合わせられる。In the first step, the lid swings around the connecting member about the center point (B) of the head having a substantially circular cross section at the tip of the fourth engaging portion of the fourth hinge forming portion of the connecting member. Then, in a state where the lid is opened approximately 100 ° with respect to the connecting member, the tip end portion of the second overhanging portion of the second hinge forming portion is housed in the concave portion of the fourth hinge forming portion, and the fourth hinge forming portion is formed. The fourth engaging portion of the portion and the tip of the second overhanging portion of the second hinge forming portion are engaged with each other.

開かれるようなことがあっても、何ら差支えない。Due to the resistance of the hinge portion when the lid is opened and closed, etc., for example, in the first step, the connecting member is opened together with the lid by about 100 ° with respect to the upper edge of the box body opening, and then the In two steps, only the lid further opens about 100 ° with respect to the connecting member after opening about 100 °, and as a result, the lid opens about 200 ° via the connecting member to the upper edge of the box body opening.
Even if it is opened, there is no problem.
【００１３】このように、この発明によれば、工具箱等

の製作時、蓋の取付工数を大幅に削減することができ、
しかも取付精度を確実に出すことができる。In a box such as the tool box described above, the box body, the lid and the connecting member may be simply combined, so that the number of man-hours for attaching the lid can be significantly reduced when the box is manufactured.
Moreover, the mounting accuracy can be reliably achieved.
