摘要： A rack-pinion type steering apparatus is disclosed wherein a damper (51, 52) of a synthetic resin having at least a column-shaped member or pillar-shaped member (51) is disposed, of which the one end and the other end come in contact with a support yoke (35) and a yoke plug (36), respectively. Such a damper (51, 52) restrains a teeth beating noise generated by a rack (4a) and a pinion (8a), from being propagated from the support yoke (35) to the yoke plug (36), lowers its noise pressure level or changes its noise quality.
