Next, with reference to FIG. 5 and FIG. 6, the effect of this Embodiment is demonstrated.
As shown in FIG. 5, for example, when a small object such as a security buzzer, a food bag, or a regular bag hung on the hanging member 100 is pulled by a person or the like, a tensile force is applied from the hanging member 100 to cause the hook portion 30 to move. It rotates in the circumferential direction of the shaft body 20a. In this state, the gap 32c between the proximal end 32a and the distal end 32b of the bending portion 32 is not expanded. That is, the gap 32c between the proximal end 32a and the distal end 32b of the bending portion 32 is smaller than the diameter of the shaft body 20a. For this reason, the hook part 30 does not come off from the shaft body 20a.

  Subsequently, as shown in FIG. 6, for example, when an accessory such as a security buzzer, a food bag, or a regular bag hung on the hanging member 100 is caught by an automobile or the like, a tensile force is applied from the hanging member 100. The curved portion 32 of the hook portion 30 is deformed. That is, when a large tensile force is applied from the hanging member 100, the bending portion 32 comes into contact with the shaft body 20a, so that the gap 32c between the proximal end 32a and the distal end 32b of the bending portion 32 is expanded. Specifically, the bending portion 32 is deformed so that the gap 32c between the proximal end 32a and the distal end 32b is larger than the diameter of the shaft body 20a. In this manner, in the hanging member 10 according to the embodiment of the present invention, the hook portion 30 can be removed from the main body portion 20. Thereby, when the tensile force acts from the hanging member 100, the breakage of the hanging member 10 can be suppressed.

  In addition, when the hook part 30 is removed from the main body part 20, the hanging member 10 can be used again by attaching the removed hook part 30 to the main body part 20 again.

  If the main body 20 is removed from the hook 30 and lost, the hanging member 10 can be used again by replacing only the hook 30. For this reason, a repair period can be shortened. Furthermore, repair costs can be reduced.

  According to the suspension member 10 of the embodiment of the present invention, the folded portion 31b is folded back to the opposite side of the gap 32c with respect to the flat plate portion 31a, so that a tensile force is applied from the hanging member 100 to the folded portion 31b. At this time, the shaft body 20a is easily removed from the gap 32c. For this reason, it is easy to remove the hook part 30 from the main body part 20.

  A school bag according to an embodiment of the present invention includes the suspension member 10 described above. For this reason, the school bag provided with the suspension member 10 which can suppress a failure | damage when tensile force acts from the hanging member 100 can be provided.

  In the above description, the school bag has been described as an example of the shoulder bag of the embodiment of the present invention. However, the hanging member 10 of the embodiment of the present invention may be used for a shoulder bag other than the school bag. Moreover, although the case where the suspending member 10 was attached to the gusset belt 4 was demonstrated above, the suspending member 10 of one embodiment of this invention may be attached to the shoulder belt (shoulder belt) 2.
