PROBLEM TO BE SOLVED: To constantly keep the inside shape of a backpack in both cases where a space is formed between the carrying face of the backpack and the back of a user and where the carrying face of the backpack is closely stuck to the back of the user, to improve the air permeability when forming the space and to effectively use all components. SOLUTION: Spacers 3 and 4 are attached to left/right lower parts of the carrying face of the backpack 1 movably between the carrying face and the side faces of the backpack, when the spacers are moved to the carrying face of the backpack, the space is formed between the carrying face of the backpack and the back of the user, and when the spacers are moved to the side faces of the backpack, the carrying face of the backpack is closely stuck to the back of the user. The use of the spacers can constantly keep the inside shape of the backpack to improve the air permeability when the space is formed and to effectively use all the components.
