The present invention relates to a pumping device for a seat cushion of a vehicle, in which a brake assembly 40 is disposed outside a clutch assembly 30 and parts are arranged in a line, such that it is possible to reduce the entire size, volume, and weight, thereby reducing cost. Further, because it is possible to prevent pollution of parts, it is possible to improve the durability, performance, and quality. Furthermore, it is possible to reduce operational noise and improve operational sensitivity.
