A bladder-inflating structure including a resilient air chamber having a receiving space which can be reciprocally compressed and released. After released, the resilient air chamber itself can resiliently restore to its original state. An inflatable bladder is connected to one side of the resilient air chamber. An intake valve is disposed on the resilient air chamber. When the resilient air chamber is compressed and released, the intake valve only permits external air to one-way flow into the receiving space. A one-way membrane nozzle is disposed on one side of the resilient air chamber between the receiving space and the bladder. The one-way membrane nozzle is composed of two soft thin membranes. The peripheries of the soft thin membranes are partially fused with each other to define a fluid passage. The fluid passage has an inlet end extending into the receiving space and an outlet end extending into the bladder. The one-way membrane nozzle only permits the fluid to one-way flow from the receiving space of the resilient air chamber into the bladder to inflate the bladder.
