The present invention relates to a pumping device of a seat for a vehicle, including: an input member rotated by the input of a torque from a handle lever; a clutch portion for transmitting the input torque to a link means of a seat cushion; a brake portion for blocking the torque reversely input from the link means; a housing accommodating the clutch portion therein; and a fixing member coupled to a rear end of the housing to be fastened to one side of the seat. The input member includes: a first input member provided outside the front of the housing; and a second input member forcibly connected to the first input member and accommodated inside the housing. The clutch portion includes: a torque transmitting member disposed on an outer circumferential surface of the second input member; and an annular control member having a clutch friction surface frictionally engaged with the torque transmitting member on an inner circumferential surface thereof and having annular front and rear shapes that are opened. As such, the present invention can significantly reduce the weight thereof,easily manage a tolerance when being manufactured through a simple structure, and remarkably reduce manufacturing cost.
