The inner frame receiving springs 12 and 12 are formed by bending the front edge of the lower drainer 3 obliquely rearward to form the inner frame receiving springs 12 and 12 so that the inner frame 8 is always resiliently upwardly sewn and both sides of the lower end of the inner frame 8 are The engaging projections 14, 14 that are engaged with the engaging recesses 13, 13 are provided on both inner walls of the inner frame fitting recessed portion 6, and the engaging recesses 13,
The engagement between 13 and the engagement protrusions 14 and 14 is used to prevent the retainer from slipping forward and backward.

Further, in the second embodiment as the engagement / disengagement mechanism 11, a spring type slide lock 15 is provided on the lower back surface of the middle frame 8 so as to be slidable up and down as shown in FIGS. 3, 4 and 5. I am supposed to. The slide lock 1 shown in this embodiment
5 is a sliding frame 17 that can slide along the inside of the outer frame 16 on the lower rear surface of the middle frame 8 and has a locking leg portion 20 with a tapered surface 19 that is always formed at the lower end under the spring of the spring 18. Box body 1
It is mounted so as to reach a position where it engages along the stopper piece 21 provided on the lower edge of the upper side. Reference numeral 22 is a slide stopper for preventing the sliding frame 17 from coming out from below the outer frame 17 by the spring 18. When the lower end of the middle frame 8 is pushed from the front side of the box body 1 toward the middle frame fitting concave portion 6, the taper surface 19 guides the taper surface 19 against the elastic force of the spring 18. Then, the sliding frame 17 automatically rises, and the stopper piece 2
This is for allowing the sliding frame 17 to automatically descend by the elastic force of the spring 18 when the vehicle tops the upper end of 1, and to be restored to the position where it is engaged along the stopper piece 21.
