On the other hand, when the engagement release member 40 moves in the pushing direction from the initial position, the locking claw 44 can move along the groove portion 18 .

As shown in FIG. 5, the container body 10 has a pair of support walls 60 on both sides of the base 17 in the width direction, which face the support surface 15 with a gap therebetween. In the present embodiment, the pair of support walls 60 are integrally connected to the side surfaces of the pedestal portion 17 . The lower surfaces of the pair of support walls 60 are planes parallel to the support surface 15 . A part of the upper surface of the pair of support walls 60 on the front side forms an inclined surface that continues to the first inclined surface 17a.

One slide wall (first slide wall) 42 of the disengagement member 40 is arranged between the support surface 15 and one support wall 60 and held therebetween. The other slide wall (second slide wall) 42 of the disengagement member 40 is arranged between the support surface 15 and the other support wall 60 and held therebetween. The distance between the support surface 15 and each support wall 60 is slightly larger than the thickness of each slide wall 42 in the vertical direction, and the thickness of the slide wall 42 of the locking claw 44 is greater than the thickness of the slide wall 42 in the vertical direction. It is smaller than the dimension plus the amount of protrusion from the bottom surface. Therefore, the engagement releasing member 40 is configured such that the locking claws 44 are locked to the locking surfaces 18a of the grooves 18 while the respective slide walls 42 are held between the supporting surfaces 15 and 60. , are held against the container body 10 so as not to come off.
