The vertical dimension of the engaging recess 13 is larger than that of the locking claw 18 so that the locking claw 18 can be fitted into the engaging recess 13 with a margin.

As shown in FIG. 10, attachment holes 19, 19 having a tapered rear half are formed in the upper and lower ends of the right half of the attachment member 14.
As shown in FIGS. 5 and 6, the countersunk screw 20 inserted from the rear of the upper and lower mounting holes 19 is screwed into two upper and lower female screw holes 21 drilled on both lower sides of the backboard 4. The left and right attachment members 14 are fixed to both lower sides of the backboard 4.

After fixing the attachment member 14, the left and right side bag-like portions 8a in the bag stitching portion 8 of the pocket body 5 after the vertical core member 6 is inserted between the opposing surfaces of the concave portion 17 and the rear surface of the backboard 4. , 8a is detachably fitted, and a fitting groove 22 that opens outward is formed (see FIGS. 3 to 5).
The other connecting piece 12b of the hook-and-loop fastener 11 fixed to the lower portion of the backboard 4 is positioned between the lower end portions of the left and right mounting members 14, as shown in FIG.

  In order to attach the pocket main body 5 to the rear surface of the backboard 4, first, the left and right side bags of the pocket main body 5 are arranged with the left and right vertical core members 6, 6 facing the front with the engaging recesses 13 formed on the left and right vertical core members 6, 6. The lateral core material 7 is inserted into the lower bag-shaped portion 8 b of the bag stitching portion 8 from either the left or right opening 9 while being inserted into the shaped portions 8 a, 8 a from the left and right openings 9, 9. After the horizontal core member 7 is inserted, it is positioned between the opposing surfaces of the lower end portions of the left and right vertical core members 6.

  Next, as shown by a two-dot chain line in FIG. 6, the left and right side bag-like portions 8 a and 8 a into which the vertical core member 6 is inserted are folded forward and inward, and then the folded side bag-like portions. As shown in FIGS. 3 to 5, 8 a is formed in the recesses 17 of the left and right mounting members 14, 14 fixed to the rear surface of the backboard 4, that is, between the opposing surfaces of the recess 17 and the backboard 4. The fitting groove 22 is fitted from the outside. At this time, either one of the side bag-like portions 8a is first fitted into either one of the right and left fitting grooves 22, and then the other side bag-like portion 8a is pulled outward of the pocket body 5. The other fitting groove 22 is preferably fitted while being extended.

  When the folded left and right side bag-like portions 8a are fitted into the fitting groove 22 together with the longitudinal core member 6, the upper and lower locking claws formed on the mounting member 14 as shown in FIG. 18, the upper and lower engaging recesses 13 of the vertical core member 6 that are reversed in the front-rear direction and opened rearward are fitted, and the front end of the locking claw 18 is inward of the engaging recess 13 together with the net of the bag stitching portion 8.
