Rack and pinion steering device

摘要

A rack and pinion steering device which reduces the generation of unusual sounds or vibrations. An auxiliary shaft (36) is slidably supported by a pair of bearings (32) and (34). The pair of bearings are arranged parallel to a rack shaft (10) at a predetermined interval on a device unit (1) which supports the rack shaft (10) in such a manner that the rack shaft (10) can reciprocate. A spherical portion (60) is formed on the end of the rack shaft (10) and swingably engaged in a connecting member (58) to interconnect the end of the rack shaft (10) and the connecting member (58). The end of the auxiliary shaft (36) is also fixed to the connecting member (58), and opposite tie rods (38) and (40) are connected to the auxiliary shaft (36) between a pair of bearings (32) and (34) via ball joints (42) and (44).
