An automobile seat leg support driving device comprises a power device, a transmission mechanism, an output screw rod, a sliding block nut and an outer shell, the output screw rod is in transmission connection with the power device through the transmission mechanism, the sliding block nut is connected with the output screw rod, and the outer shell is arranged outside the sliding block nut in a sleeving mode and can move up and down and/or back and forth. And a connecting structure connected with the leg support is arranged on the outer shell. The outer shell of the automobile seat leg support driving device can move up and down and back and forth by a certain distance so as to adapt to movement or distortion of the output screw rod in the two directions, it is ensured that the leg support can be installed at the preset position without the phenomena of rotation blocking or clamping and the like, and meanwhile bending deformation of the output screw rod can be prevented.
