To inhibit a hole cover fitted in a housing from being fallen by external force in a rack-and-pinion mechanism.SOLUTION: A rack-and-pinion mechanism includes: a housing 10; a hole cover 13 which is fitted on the housing 10 and covers a part of a pinion shaft 107; and a seal member 20 which is an annular O ring or an irregular-shaped ring sandwiched between an outer peripheral surface of the housing 10 and an inner peripheral surface of the hole cover 13. The hole cover 13 has a cylindrical female fitting part 13a. The housing 10 has a cylindrical male fitting part 10b into which the pinion shaft 107 is inserted and which is press-fitted in the female fitting part 13a.SELECTED DRAWING: Figure 3

    【課題】ラックアンドピニオン機構において、ハウジングに対して嵌合されたホールカバーが外力によって倒れるのを抑制する。【解決手段】ラックアンドピニオン機構は、ハウジング10と、ハウジング10に外嵌されてピニオン軸107の一部を覆うホールカバー13と、ハウジング10の外周面とホールカバー13の内周面との間に挟持される環状のOリング又は異形リングであるシール部材20と、を備える。ホールカバー13は、円筒状の雌嵌合部13aを有し、ハウジング10は、ピニオン軸107が挿入されるとともに雌嵌合部13aに圧入嵌めされる円筒状の雄嵌合部10bを有する。【選択図】図3
