The invention discloses a pressure generating device for a vehicle braking system. The pressure generating device comprises a motor, a hydraulic control valve block, a cylinder body, a piston, an anti-rotation sleeve, a nut, a lead screw, a motor rotor, a sliding block and a hydraulic cavity. Wherein the motor rotor is fixedly connected with one end of the lead screw through a nut; the motor is fixedly connected with the hydraulic control valve block through bolts; the cylinder body is axially inserted into a cylindrical hole of the hydraulic control valve block and is fixed; the piston is axially inserted into the cylinder body; one end of the piston is fixedly connected with the nut; a mounting hole is formed in the radial direction of the nut, and the sliding block is mounted in the mounting hole of the nut; a convex rib is arranged on the anti-rotation sleeve, a groove is formed in the sliding block, the convex rib is in matched contact with the groove, and the sliding block can slide linearly in the axial direction of the convex rib; one end of the anti-rotation sleeve is fixedly connected with the cylinder body. Coaxiality deviation of the anti-rotation sleeve, the cylinder body and the piston can be reduced, the problem caused by welding of a flat key and a nut is solved, and the lubricating effect between the sliding block and a friction pair of the anti-rotation sleeve is improved.
