- a part having a wide shape and widened in a right-left direction of the mesh net 10 is contacted with an upper lumber, and the mesh net 10 curves around and contacts with the upper lumber to disperse a load come from the storage part 2. This prevents the supporter 4 from being uneven load and reduces a physical burden of the wearer P.
- An outline of the annular frame 11 is larger than that of the storage part 2. This allows an area of the mesh net 10 contacted firmly with the body of the wearer P to expand regardless of a size of the storage part 2, thereby dispersing a weight of the backpack 1 to wear.
- a distance is formed between the ball members 13, 13 of the backpack 1 and storage part 2 to have a three-layer structure.
- This structure allows the back-side surface BP of the back plate 24 of the storage part 2 not to contact with the back PB directly, thereby passing air through mesh net 10 and dissipating heat.
- the back plate 24 of the storage part 2 facing to the wearer P see FIG. 2
- the ball members 13, 13 placed between the back plate 24 and the mesh net 10 contacts with the back-side surface BP, thus the distance is maintained, and a ventilation improves.
- the back plate 24 is apart from the curving back PB and even if the back PB bends, the storage part 2 is hard to be deformed.
- the storage part 2 therefore, efficiently receives electric devices such as a tablet or a laptop computer, which might be damaged.
- Receiving objects having appropriate weight of 1 to 5 kilograms, preferably 2.5 kilograms in the storage part 2 appropriately adjusts a force where the ball members 13, 13 press a part between the eighth thoracic spine F8 and the tenth thoracic spine F10 of the wearer P.
- the storage part 2 as shown in FIG. 2 , pulls shoulders PS of the wearer P in a behind direction of B1 with a position of the ball members 13, 13 as a fulcrum to be better for a round back.
- the supporter 4 having a better holding property is hard to be shifted. As shown in Fig. 5 , this allows the storage part 2 to move relatively in a swing direction of U where swing center is the ribbon ring 9a hanged on the belt insertion part 17 while the ball members 13, 13 still contact with a desired point. A movement of the storage part 2 in a swing direction of U whose swing center is the hanging ribbon 9 may be measured with a measuring instrument such as an angle sensor and a measured data may be transferred to the wearer P's smart phone.
- a measuring instrument such as an angle sensor
- the backpack 1 of the present embodiment easily and removably attaches the storage part 2 to the supporter 4. It is easy to determine a position between the storage part 2 and the supporter 4.
- the ball members 13, 13 is arranged at the same position.
- a knapsack or a backpack having a different shape from the storage part 2 can be attached to the supporter 4 according to a purpose of use.
- the wearer P wears the backpack 1 again after putting it off, the ball members 13, 13 are arranged at the same position and the wearer P obtains the same massaging effect.
- the locknut 11a and the screw part 11b are fastened together after a pair of the upper ends 11h, 11h is inserted into the hanging ribbon 9 attached to an upper part of the storage part 2.
- the belt insertion part 17 is larger than the ribbon ring 9a. This allows the hanging ribbon 9 to be hard to come off from the belt insertion part 17 and further to support the storage part 2 stably.
