An automobile front wheel transmission steering device comprises an outer ring seat, an inner ring seat, a retainer and a plurality of balls. The outer ring base is provided with a plurality of outergrooves, and the number of the outer grooves is an even number larger than or equal to six. The inner ring base is provided with a plurality of inner grooves, and the number of the inner grooves is afactor of the number of the outer grooves and is larger than or equal to three. The retainer is arranged on the outer ring base and the inner ring base and comprises a plurality of through holes, andthe number of the through holes is larger than or equal to three. The balls are installed on the retainer in a rolling mode, the number of the balls is a factor of the number of the outer grooves, andthe number of the balls is larger than or equal to three and not equal to the number of the outer grooves. The number of the outer grooves is larger than that of the balls, so that the outer groovescan be used successively, the service life is prolonged, and the maintenance cost is reduced.
