Abstract: A transmission device and a rack corner steering mechanism, the rack corner steering mechanism comprises an input gear (10) and a rack steering assembly (20), the rack steering assembly (20) comprises a plunger (21) and a plurality of rack units (22), the plunger (21) is a straight bar and is moved along a straight trajectory, and the plunger (21) adjacent to the rack unit (22) is obliquely connected to an end of the plunger (21), each of the other rack units (22) is successively connected to the end of the front rack unit (22), when each rack unit (22) is engaged with the input gear (10), the rack unit (22) is rotated and is in line with the plunger (21). The rack unit (22) can be rotated to ensure the flexible steering of the steering mechanism, the reciprocating motion of the input gear (10) is converted into the reciprocating motion of the plunger (21), which has the advantages of smooth operation, good continuity, low noise, high bearing capacity, reliable, compact structure, and small volume.
