[0031] Case 12a includes a groove G. The groove G is located on the upper side of the shoulder pad 10 in the longitudinal direction. The groove G is located on one end side in the longitudinal direction of the shoulder pad 10. The groove G extends in the longitudinal direction of the shoulder pad 10. The groove G is configured to be recessed from the surface of case 12a. The groove G is located between the first mounting portion 11a and the third mounting portion 11c in the longitudinal direction of the shoulder pad 10. The groove G extends along the shape of case 12a. In this embodiment, the groove G is curved along the shape of case 12a. The groove G is located outside the center in the width direction of the shoulder pad 10. In this embodiment, the width of the groove G is greater than the depth of the groove G.

[0032] As shown in Figures 4 and 5, the bead cushion 12b includes a first partition P1. The first partition P1 is located on the upper side in the longitudinal direction of the shoulder pad 10. The first partition P1 is located on one end side in the longitudinal direction of the shoulder pad 10. The first partition P1 extends in the longitudinal direction of the shoulder pad 10. The first partition P1 is configured to divide the bead cushion 12b into multiple regions. In this embodiment, the first partition P1 is configured to divide the bead cushion 12b into two regions in the width direction of the shoulder pad 10. In this embodiment, the first partition P1 is constructed by sewing the front and back surfaces of the bead cushion 12b. The groove G is configured to overlap the first partition P1. The groove G is configured to fit into a recess formed when the bead cushion 12b is partitioned by the first partition P1.

[0033] The bead cushion 12b includes a second partition P2. The second partition P2 is located on the underside of the shoulder pad 10. The second partition P2 is located on the other end side in the longitudinal direction of the shoulder pad 10. The second partition P2 extends in the longitudinal direction of the shoulder pad 10. The second partition P2 is configured to divide the bead cushion 12b into multiple regions. In this embodiment, the second partition P2 is configured to divide the bead cushion 12b into two regions in the width direction of the shoulder pad 10. In this embodiment, the second partition P2 is constructed by sewing the front and back surfaces of the bead cushion 12b.

[0034] In this embodiment, the outer periphery of the outer material 12b1 of the bead cushion 12b is sewn all the way around. The outer material 12b1 includes an overhang that extends outward from the sewn portion.

[0035] The bead cushion 12b includes a connecting section C between the first partition section P1 and the second partition section P2. The connecting section C is configured such that beads 12b2 move through the connecting section C within the bead cushion 12b.

[0036] Case 12a includes an outer member 12a1 and an inner member 12a2. The outer member 12a1 is positioned facing the shoulder strap 3. The inner member 12a2 is positioned on the opposite side of the shoulder strap 3 from the outer member 12a1. The inner member 12a2 is positioned facing the user's shoulder. The inner member 12a2 is constructed of a stretchable mesh. In this embodiment, the longitudinal and transverse stretch ratio of the mesh material of the inner member 12a2 is 110% or more and 140% or less.

[0037] A modified example of the shoulder pad 10 in the embodiment will be described with reference to Figure 6. In the above example, the inner member 12a2 of case 12a is made of mesh material, but in a modified example of the shoulder pad 10 in the embodiment, the inner member 12a2 of case 12a is made of synthetic leather material.

[0038] Next, the effects and advantages of the embodiment will be described. In the embodiment of the shoulder pad 10, the main body 12 of the shoulder pad 10 includes a bead cushion 12b inserted into a case 12a. Because the bead cushion 12b conforms well to the shape of the user's shoulder, it can improve the fit to the user's shoulder. Therefore, a shoulder pad 10 with a high degree of fit can be provided.

[0039] In the embodiment of the shoulder pad 10, the case 12a is positioned above the shoulder pad 10 in the longitudinal direction and includes a groove G that extends in the longitudinal direction of the shoulder pad 10. As a result, the mountain-shaped inner surface of the shoulder belt 3 fits into the groove G, allowing the shoulder belt 3 and the shoulder pad 10 to be more closely fitted together.

[0040] In the shoulder pad 10 of this embodiment, the bead cushion 12b is positioned above the shoulder pad 10 in the longitudinal direction and includes a first partition P1 that extends in the longitudinal direction of the shoulder pad 10. Therefore, by dividing the bead cushion 12b into multiple regions with the first partition P1, it is possible to suppress the flow of the beads 12b2 within the bead cushion 12b while ensuring the fluidity of the beads 12b2.

[0041] Furthermore, the groove G is configured to overlap the first partition P1. As a result, the groove G fits into the recess formed when the bead cushion 12b is partitioned by the first partition P1, allowing the case 12a and the bead cushion 12b to be more closely fitted together.

[0042] In the shoulder pad 10 of this embodiment, the bead cushion 12b is positioned below the shoulder pad 10 and includes a second partition P2 that extends in the longitudinal direction of the shoulder pad 10. Therefore, by dividing the bead cushion 12b into multiple regions with the second partition P2, it is possible to suppress the flow of the beads 12b2 within the bead cushion 12b while ensuring the fluidity of the beads 12b2.

[0043] In the shoulder pad 10 of this embodiment, the bead cushion 12b includes a communication section C between the first partition section P1 and the second partition section P2. The communication section C is configured such that beads 12b2 move through the communication section C within the bead cushion 12b. Therefore, beads 12b2 can be enclosed in the area separated by the first partition section P1 and the area separated by the second partition section P2 of the bead cushion 12b through the communication section C.

[0044] In the shoulder pad 10 of this embodiment, the inner member 12a2 is configured as a stretchable mesh. Therefore, the fluidity of the beads 12b2 can be ensured so that the beads 12b2 inside the bead cushion 12b move according to the shape of the user's shoulder.

[0045] Furthermore, in the mounting member 11, the first mounting portion 11a, the second mounting portion 11b, and the third mounting portion 11c are spaced apart from each other in the longitudinal direction of the shoulder pad 10. This makes it easy to bend the shoulder pad 10 along its longitudinal direction when it is attached to the shoulder belt 3. Thus, flexibility in the longitudinal direction of the shoulder pad 10 can be ensured.

[0046] Furthermore, the third mounting portion 11c forms a loop with the main body portion 12. Therefore, because the shoulder strap 3 is inserted through the third mounting portion 11c, even if the first mounting portion 11a and the second mounting portion 11b detach from the shoulder strap 3, the shoulder pad 10 is prevented from detaching from the shoulder strap 3.

[0047] Furthermore, the groove G is positioned outside the center in the width direction of the shoulder pad 10. A gap is more likely to occur between the shoulder pad 10 and the shoulder strap 3 on the user's shoulder side than on the user's neck side. Because the groove G is positioned outside the center in the width direction of the shoulder pad 10, the shoulder pad 10 and the shoulder strap 3 can be effectively brought into close contact on the user's shoulder side.

[0048] Furthermore, the outer material 12b1 of the bead cushion 12b includes an overhang that extends outward from the sewn portion. If the outer material 12b1 includes an overhang inside the sewn portion, the overhang is located inside the outer material 12b1, and the amount of beads 12b2 enclosed inside the outer material 12b1 is affected by the overhang. By positioning the overhang of the outer material 12b1 outside the sewn portion, the amount of beads 12b2 enclosed inside the outer material 12b1 is not affected by the overhang, and the amount of beads 12b2 can be stabilized.

[0049] The backpack bag 100 in this embodiment is equipped with shoulder straps 3 to which shoulder pads 10 are attached. Therefore, it is possible to provide a backpack bag 100 equipped with shoulder pads 10 that offer a high level of fit.

[0050] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description and is intended to include all modifications in the sense and scope equivalent to the claims.
