The invention relates to the field of automobile steering systems, in particular to a supporting seat clearance automatic compensation structure for a rack-and-pinion steering gear. Comprising a gear seat and a gear shaft rotationally connected with the gear seat, and further comprises a bearing base fixedly arranged on the side of the gear seat; the tight supporting mechanism is arranged on the side, close to the gear seat, of the bearing base and comprises a tight supporting spring, a tight abutting short shaft, a tensioning short shaft and two fastening tension springs, one end of the tensioning short shaft is fixedly connected with the gear seat, the tight abutting short shaft is arranged on the side, away from the gear seat, of the tensioning short shaft, the tight supporting spring is arranged outside the tight abutting short shaft in a sleeving mode, and the two fastening tension springs are arranged on the two sides of the tensioning short shaft. The two fastening tension springs are arranged on the two sides of the tensioning short shaft respectively. The calibration mechanism is connected with the bearing base and comprises a traction rope capable of driving the abutting short shaft to move; the metering mechanism is arranged on the side, away from the abutting short shaft, of the bearing base and comprises a dial capable of mapping the moving degree of the abutting short shaft. According to the structure, the gap of the gear shaft can be automatically adjusted, and an operator can conveniently check the intermittent adjustment degree.
