The present invention relates to a support bag for a knapsack. The support bag for a knapsack may be connected or fixed to shoulder straps thereof using two rings which are disposed at upper and lower ends of a rear side thereof to locate the support bag on a position corresponding to the chest. Thus, valuables such as a tablet PC may be securely stored. In particular, the ring disposed at a rear upper portion of the support bag may be disposed at a position leaning toward a rear side from a vertical center line of an upper end of an inner surface facing the chest of the user to prevent the support bag from being shaken in left and right directions when the user moves. The support bag for a knapsack according to an embodiment of the present invention includes: a bag body having a receiving space therein, the bag body including a ?-shaped zipper member, which opens and closes the receiving space according to whether the user moves, on an edge thereof; a first ring disposed on a rear lower end of the bag body; and a second ring disposed on a rear upper end of the bag body, the second ring being disposed leaning toward a rear side from a vertical center line of an upper end of an inner surface facing the chest of the user to prevent the support bag from being shaken in left and right directions. |
