Abstract
Disclosed is a seat pumping device for a vehicle. The seat pumping device includes: a housing; a return spring guide which is fixedly coupled to the housing and has an embedded return spring; a clutch cam which is rotatably accommodated in the housing; and a lever bracket which is partially accommodated in the return spring guide and coupled to the clutch cam so as to be rotated integrally with the clutch cam, in which the lever bracket is maintained spaced apart from the return spring guide by a separation support means, thereby improving operating characteristics of a lever handle.
