In this embodiment, the first partition P1 is formed 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 by dividing the bead cushion 12b by the first partition P1.

[0033] The bead cushion 12b includes a second partition P2. The second partition P2 is disposed below the shoulder pad 10. The second partition P2 is disposed 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 formed by sewing the front and back surfaces of the bead cushion 12b.

[0034] In this embodiment, the outer periphery of the exterior member 12b1 of the bead cushion 12b is sewn around the entire periphery, and the exterior member 12b1 includes a protruding portion that protrudes outward from the sewn portion.

[0035] The bead cushion 12b includes a communication portion C between the first partition portion P1 and the second partition portion P2. The communication portion C is configured so that the beads 12b2 move through the communication portion C inside the bead cushion 12b.

[0036] The case 12a includes an outer member 12a1 and an inner member 12a2. The outer member 12a1 is disposed so as to face the shoulder belt 3. The inner member 12a2 is disposed on the opposite side of the outer member 12a1 from the shoulder belt 3. The inner member 12a2 is disposed so as to face the user's shoulder. The inner member 12a2 is formed in a stretchable mesh shape. In this embodiment, the stretch ratio of the mesh material of the inner member 12a2 in the vertical and horizontal directions is 110% or more and 140% or less.

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

[0038] Next, the effects of the embodiment will be described. According to the shoulder pad 10 of this embodiment, the main body 12 of the shoulder pad 10 includes a bead cushion 12b inserted into a case 12a. The bead cushion 12b has a high degree of conformability to the shape of the user's shoulder, improving the fit to the user's shoulder. Therefore, a shoulder pad 10 with a high fit can be provided.

[0039] According to the shoulder pad 10 of this embodiment, the case 12a is disposed on the upper side of the shoulder pad 10 in the longitudinal direction and includes a groove G extending in the longitudinal direction of the shoulder pad 10. Therefore, 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 attached to each other.

[0040] According to the shoulder pad 10 of this embodiment, the bead cushion 12b is disposed on the upper side of the shoulder pad 10 in the longitudinal direction and includes a first partition P1 extending in the longitudinal direction of the shoulder pad 10. Therefore, by dividing the inside of the bead cushion 12b into multiple regions by the first partition P1, it is possible to prevent the beads 12b2 from flowing down inside 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. Therefore, the groove G fits into a recess formed by partitioning the bead cushion 12b with the first partition P1, thereby enabling the case 12a and the bead cushion 12b to be more closely attached to each other.

[0042] According to the shoulder pad 10 of this embodiment, the bead cushion 12b is disposed below the shoulder pad 10 and includes a second partition P2 extending in the longitudinal direction of the shoulder pad 10. Therefore, by dividing the inside of the bead cushion 12b into multiple regions by the second partition P2, it is possible to prevent the beads 12b2 from flowing down inside the bead cushion 12b while ensuring the fluidity of the beads 12b2.

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

[0044] According to the shoulder pad 10 of this embodiment, the inner member 12a2 is made of a stretchable mesh, which ensures the fluidity of the beads 12b2 so that the beads 12b2 in the bead cushion 12b can move in accordance with the shape of the user's shoulder.

[0045] Furthermore, in the attachment member 11, the first attachment portion 11a, the second attachment portion 11b, and the third attachment portion 11c are arranged at intervals in the longitudinal direction of the shoulder pad 10. This makes it easy to bend the shoulder pad 10 along the longitudinal direction of the shoulder pad 10 when the shoulder pad 10 is attached to the shoulder belt 3. This ensures flexibility of the shoulder pad 10 in the longitudinal direction.

[0046] Additionally, the third attachment portion 11c forms a loop with the main body portion 12. Therefore, by inserting the shoulder belt 3 into the third attachment portion 11c, even if the first attachment portion 11a and the second attachment portion 11b fall off the shoulder belt 3, the shoulder pad 10 can be prevented from falling off the shoulder belt 3.

[0047] Furthermore, groove G is located outside the center in the width direction of shoulder pad 10. A gap is more likely to form between shoulder pad 10 and shoulder belt 3 on the shoulder side of the user than on the neck side. Because groove G is located outside the center in the width direction of shoulder pad 10, shoulder pad 10 and shoulder belt 3 can be effectively brought into close contact with each other on the shoulder side of the user.

[0048] Additionally, exterior member 12b1 of bead cushion 12b includes a protruding portion that protrudes outward from the sewn portion. If exterior member 12b1 includes a protruding portion inside the sewn portion, the protruding portion is positioned inside exterior member 12b1, and the protruding portion affects the amount of beads 12b2 enclosed in exterior member 12b1. However, since the protruding portion of exterior member 12b1 is positioned outside the sewn portion, the protruding portion does not affect the amount of beads 12b2 enclosed in exterior member 12b1, and the amount of beads 12b2 enclosed can be stabilized.

[0049] Backpack 100 in this embodiment is equipped with shoulder straps 3 equipped with shoulder pads 10. Therefore, it is possible to provide backpack 100 equipped with shoulder pads 10 that provide a comfortable fit.

[0050] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
