In the state where the bent portion 24 is not bent (FIG. 5), the protrusions 28a and 28b are continuous in a straight line, and in the state where the bent portion 24 is bent (FIG. 9), the protrusions 28a and 28b are hinge portions 26. Is a predetermined angle with
[0016]
And in the protrusion 28b of the bending part 24, the protrusion-shaped 1st press part 30 is formed in the side surface by the side of the opening 14 in the vicinity of the hinge part 26, and in the position spaced apart from the 1st press part 30 by predetermined spacing. A projecting second pressing portion 32 is formed on the side surface opposite to the opening 14. Here, the distance H (FIG. 6) between the vertex of the first pressing portion 30 and the vertex of the second pressing portion 32 is set to be slightly larger than the width of the groove 42 provided in the lid body 18. Therefore, when the 1st press part 30 and the 2nd press part 32 are inserted in the groove 42, these will be pressed by the side surface of the groove 42, and the front-end | tip part of the bending part 24 will be pushed up to the obstruction | occlusion surface A side.
[0017]
Further, a grip portion 34 is formed at the distal end portion of the bent portion 24 by increasing the thickness of its side wall, and a plurality of grooves 34 a for hooking fingers are formed on the outer surface of the grip portion 34.
[0018]
In addition, such a box 16 is integrally formed by injection molding of a synthetic resin such as PP (polypropylene).
[0019]
As shown in FIGS. 7 and 8, the lid 18 has a lid plate 36 having a closing surface A that closes the opening 14 of the box 16, and is perpendicular to the closing surface A from both ends in the width direction of the lid plate 36. Are formed by two side plates 38 extending in the vertical direction and a side plate 40 extending perpendicularly to the closing surface A from one longitudinal end of the lid plate 36.
[0020]
However, the side plates 38 and 40 are not formed at the other end in the longitudinal direction of the lid plate 36 in order to secure a space S in which the grip portion 34 of the box 16 is accommodated. Therefore, in the lid 18, the end on the side where the space S is secured becomes an insertion slot E (FIGS. 3 and 7) for inserting the box 16.
[0021]
And the groove | channel 42 which slidably fits with the protrusions 28a and 28b is formed in the mutually opposing surface of each side plate 38, and is extended in the sliding direction of the box body 16, Moreover, on these surfaces, In order to prevent the box body 16 from rattling, a protruding contact portion 44 that contacts the outer surface of the box body 16 is formed.
[0022]
