The invention relates to a hydraulic steering gear with lateral oil ports and belongs to the technical field of hydraulic transmission. The valve body of the steering gear is provided with two opposite end faces. The two opposite end faces are respectively provided with an oil inlet, an oil return port, a left oil port and a right oil port. The oil inlet, the oil return port, the left oil port and the right oil port are respectively located in positions among corresponding annular grooves and are respectively communicated with the oil inlet annular groove, the oil return groove, the left annular groove and the right annular groove through oblique holes. The oblique hole communicating the oil return port and the oil return annular groove is further communicated with the bottom hole of one of the connecting bolt holes, and the connecting bolt hole is communicated with the oil inlet annular groove through a short oblique hole in the valve body inner hole port. The hydraulic steering gear has the advantage that mounting is facilitated while part number and size are not increased.
