An inflation pump including a body having a cylinder and a head integrally formed with the cylinder. The cylinder includes a pressurizing space. The head includes a through-hole extending along a longitudinal axis. An intercommunication passage is disposed between and intercommunicates with the through-hole and the pressurizing space. A pressurizing unit is slidably received in the pressurizing space and is reciprocally slidable relative to the body. A nozzle unit includes a pressing device disposed in the through-hole. The pressing device includes a push seat having a check ring. The check ring includes an inner side abutting against the push seat and an outer side abutting against a portion of an inner periphery of the through-hole. The portion of the inner periphery of the through-hole is located between the intercommunication passage and the coupling end. The check ring permits air to flow only from the intercommunication passage towards the coupling end.
