According to the present invention, a multistage transmission comprises: a drive shaft rotating as rotational force is applied thereto; a plurality of drive gears coupled to the drive shaft and rotated by rotation of the drive shaft; a plurality of transmission gears meshed with the drive gears; a gear-shifting shaft including a plurality of pawl assemblies at least partially protruding on the outer circumferential surface thereof, and coupled to the transmission gears and selectively coupled to at least some of the transmission gears according to the appearance and disappearance of at least some of the pawl assemblies; a gear-shifting control means for selectively controlling the appearance and disappearance of at least some of the pawl assemblies; a plurality of driven gears meshed with at least some of the transmission gears; and a driven shaft coupled to the plurality of driven gears to transmit rotational force to an object to be driven. Therefore, all the transmission gears can be coupled to one shaft, and the drive shaft and the driven shaft can be coaxially located, so that space efficiency is increased.
