  • the ball members 13, 13 press a desired part of the wearer P almost equally from right and left to stimulate the desired point, thus the wearer P expects a health-promoting effect.
  • the ball members 13, 13 contact with the back PB in a condition where the mesh net 10 intervenes as a cushion to reduce an impact relative to contacting with the backbones F directly.
  • the first spring 12a and the second spring 12b expand and absorb the force to prevent the ball members 13, 13 from separating each other. This reduces a position shift of the ball members 13, 13 in a right-left direction X, and the ball members 13, 13 contact accurately with the point having a better massaging effect.
  • the ball members 13, 13 With adjusting a force of sliding and contacting between the ball members 13, 13 and the mesh net 10, the ball members 13, 13 contact with the mesh net 10 along the backbones F having a roughness in a top-bottom direction Z (see FIG. 5 ). This rotates the ball members 13, 13 in a vertical direction and gives a better stimulation to nerves between the eighth thoracic spine F8 and the tenth thoracic spine F10.

  • the supporter 4 fits various body shapes to bring a better holding property.
  • the ribbon 9 hanged on the belt insertion part 17 brings a weight of the backpack 1 to the frame 11 formed by a spring member, and the upper frame 11g and the lower frame 11e curves in B1 and B2 directions toward behind the wearer P, respectively.
  • the frame members 11f, 11f further come closer to the right and left body sides PW (see FIG. 5 ) and are curved around in directions of A1 and A2 toward in front of the wearer P to improve sense of fit.
  • the supporter 4 is curved in B1 and B2 directions being close to the storage part 2 at the upper side 2a and the lower side 2b of the storage part 2.

  • 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.
