In this state, the upper shoulder belts 24, 25 can be detachably attached to the lower shoulder belts 27, 28.
The upper shoulder belt 24 and the lower shoulder belt 27 constitute a shoulder belt 21, and the upper shoulder belt 25 and the lower shoulder belt 28 constitute a shoulder belt 22.

  If you want to prevent your child from sweating and sweating between the backpack 20 and the back during summer schooling, remove the upper shoulder belts 24 and 25 from the lower shoulder belts 27 and 28. The upper shoulder belts 24 and 25 are respectively passed from the tips to the belt through holes 8 and 9 of the back strap 10 and the back strap 10 is moved to the vicinity of the upper ends of the upper shoulder straps 24 and 25, It abuts on the back support surface 23. Then, the upper shoulder belts 24 and 25 are attached to the lower shoulder belts 27 and 28 (see FIG. 6), and the shoulder belts 21 and 22 are hung on the left and right shoulders to carry the school bag 20 on the back. The bag back support 10 is mounted so that the air outlet side of the ventilation fan 4 faces the back side of the child. And the power switch of power supply BOX5 is turned ON, and it adjusts to favorite wind force with a ventilation capability adjustment part.

The ventilation fan 4 is operated by the supply of power from the power source BOX 5, and the air sucked into the space of the three-dimensional spring structure forming the backrest body 1 from the outside blows out from the ventilation fan 4 toward the back of the child ( (See arrows a and b, c and d in FIG. 7). Therefore, the child feels cool and feels comfortable on the back, and even if the child's back side sweats while walking, it evaporates by the air blown from the ventilation fan 4 and quickly passes through the gap in the back support body 1 of the bag. Since the moisture of sweat is released to the outside, sweating and stickiness due to sweat do not occur. Moreover, since the back support body 1 of a heel is comparatively lightweight and has cushioning properties, the back does not hurt and the school bag 20 does not become heavy. Further, the belt through holes 8 and 9 opened in the back rest body 1 made of a rectangular plate-shaped three-dimensional spring structure are inserted near the upper ends of the shoulder belts 21 and 22, so that they can be attached to and detached from the school bag 20.

  According to this embodiment, since the wind is forcibly sent to the back of the sweated child, the sweat is evaporated, and the moisture of the sweat is rapidly released to the outside through the gap of the back pad main body 1 of the heel. It is possible to realize the heel back support device 10 having extremely high divergence, and it does not cause sweating and sticky discomfort due to sweat. Moreover, since the back support 10 of a heel is comparatively lightweight and has cushioning properties, the back does not hurt and the school bag 20 does not become heavy. Further, the belt through holes 8 and 9 opened in the back rest body 1 made of a rectangular plate-shaped three-dimensional spring structure are inserted near the upper ends of the shoulder belts 21 and 22, so that they can be attached to and detached from the school bag 20. In addition to being easy, it is difficult for the back support body 1 of the bag to slip laterally from the back support surface 23 of the school bag 20 during use, and it is difficult to walk. The wind force can be adjusted according to the amount of sweating.

In the above-described embodiment, the pair of band-passing holes 8 and 9 are provided on the left and right sides of the upper end portion of the back rest body 1, but as shown in FIG. One band-passing long hole 31 extending in the left-right direction may be provided at the upper end of the tool body 1A. In the case of this band-passing long hole 31, the shoulder belts 21, 22 of the school bag 20 are also provided. By inserting the vicinity of the upper end of each into the both end portions of the long hole 31, it becomes difficult for the back support device 10A of the bag to be laterally displaced from the back support surface of the school bag during use.

According to this reference example, the wind is forcibly sent to the sweated child's back, the sweat is evaporated, and the moisture of the sweat is quickly released to the outside through the gap of the back support body 1 of the heel. It is possible to realize the heel back support device 10 having extremely high divergence, and it does not cause sweating and sticky discomfort due to sweat. Moreover, since the back support 10 of a heel is comparatively lightweight and has cushioning properties, the back does not hurt and the school bag 20 does not become heavy. Further, the belt through holes 8 and 9 opened in the back rest body 1 made of a rectangular plate-shaped three-dimensional spring structure are inserted near the upper ends of the shoulder belts 21 and 22, so that they can be attached to and detached from the school bag 20. In addition to being easy, it is difficult for the back support body 1 of the bag to slip laterally from the back support surface 23 of the school bag 20 during use, and it is difficult to walk. The wind force can be adjusted according to the amount of sweating.
