On the bag body 20. Each of the slots 304 is located between the two ends of the perforations 302 to prevent the first segment 402 or the second segment 404 from coming out of the corresponding slot 304.

In this embodiment, the back shell 30 has an upper section 322, a middle section 324 and a lower section 326 from top to bottom. The upper section 322 corresponds to the top of the bag body 20, and the lower section 326 corresponds to the bottom of the bag body 20, and is cut. The slot 304 and the through hole 302 are located in the middle section 324, and the upper section 322 and the lower section 326 are respectively inclined by the middle section 324 toward the outer side surface 20b of the bag body 20. Thereby, the upper section 322 and the lower section 326 can be used to attach the top and bottom of the backrest bag 1 without excessive protrusion and affecting the activities of the personnel.

The back shell 30 has two side portions 342 in the lateral direction and an intermediate portion 344 between the two side portions 342. The side portions 342 are inclined by the intermediate portion 344 toward the side edge 30c. The slots 304 and the through holes 302 are located at the side portions 342. The intermediate portion 344 has a receiving groove 344a facing the outer side surface 20b of the bag body 20. In the embodiment, the receiving portion 344a extends from the upper portion 322 to the lower portion 326. 4, after the back shell 30 is coupled to the bag body 20, an accommodating space is formed between the pocket 344a and the outer side surface 20b of the bag body 20 for vacant objects.

With the backpack 1 of the present embodiment, after the back shell 30 is coupled to the bag body 20, not only the articles in the bag body 20 but also the back of the user can be protected. When the back shell 30 is not needed, the user can also remove the back shell 30 from the bag body. Other objects such as raincoats, sleeping mats, and the like may be placed between the back shell 30 and the bag body 20.

In addition to the first and second fasteners 42, 44 as the first and second bonding members, the first and second bonding members may also be affixed to the male and female adhesives of the felt, and may be engaged with each other. Female snap button. Of course, the first segment 402 and the second segment 404 of the strap 40 can also be combined in a manner of tying. In this way, the purpose of combining the first segment 402 and the second segment 404 in a detachable manner is also achieved.

In practice, there may be only one set of fixing straps 40, and the purpose of fixing the back shell 30 to the bag body 20 is also achieved.
