Abstract: Disclosed herein is a bag configured such that the length of a bag strap used to hold the bag on a user's body is easily adjustable and an adjusted region is not exposed to the outside, thus enabling a neat appearance to be reliably maintained and allowing the bag to be safely used. The bag includes a sack-shaped main body configured to receive objects and a bag strap normally connected to the main body and used to hold the bag on a user's shoulder, waist or the like. One end of the bag strap is coupled to one end of the main body, a wire of a predetermined length is connected to the other end of the bag strap, and the main body includes an adjusting means that adjusts the length of the wire by winding or unwinding, in the state where an end of the wire is fixed.
