To provide a rack guide which can stably support a rack bar over a long time while preventing occurrence of striking sound, and to provide a gear mechanism using the rack guide.SOLUTION: A rack guide 30 slidably supports a rack bar 20 formed with a rack gear 21 which engages with a pinion gear 11 and guides the rack bar 20 which moves in response to rotation of the pinion gear 11 in an axis O2 direction of the rack bar. The rack guide 30 includes at least three projection parts 33a to 33c which protrude from an outer peripheral surface 314 along an axis O3 direction of the rack guide and slidably contact with an inner wall surface 78 of a housing 70. These projection parts 33a to 33c are disposed at positions which are asymmetrical with respect to the axis O3 of the rack guide 30.SELECTED DRAWING: Figure 4

    【課題】打音の発生を防止しつつ、長期に亘ってラックバーを安定的に支持することができるラックガイド、および、これを用いたギア機構を提供する。【解決手段】ラックガイド30は、ピニオンギア11と噛み合うラックギア21が形成されたラックバー20を摺動可能に支持して、ピニオンギア11の回転に応じて移動するラックバー20をその軸O2方向にガイドする。ラックガイド30は、その軸O3方向に沿って外周面314から突出してハウジング70の内壁面78と摺接する、少なくとも3つの突起部33a~33cを備えている。これらの突起部33a~33cは、ラックガイド30の軸O3に非対称となる位置に配置されている。【選択図】図4
