A hole cover includes a tubular fitting member (31) to be fitted to a tubular portion (12) of a rack housing (5), which houses a pinion shaft (9) such that the pinion shaft (9) partially protrudes from the tubular portion (12), and an annular seal member (32) disposed radially inward of the tubular fitting member (31). The tubular fitting member (31) includes a cover-side fitting portion (54), a cover-side interposing portion (55), and a covering portion (56). The covering portion (56) is provided with an opening (61). The opening (61) is provided so that the annular seal member (32) is exposed to an outside in a state in which the fitting of the tubular fitting member (31) to the tubular portion (12) is completed when a fitting length, which is a length of a part of the cover-side fittingportion (54) that is fitted to a housing-side fitting portion (21), is a predetermined fitting length and in a state in which the rack housing (5) is not mounted on a vehicle.

    本发明涉及孔覆盖件,包括:管状配装构件(31),其待配装至齿条壳体(5)的管状部分(12),管状部分(12)将小齿轮轴(9)容纳成使得小齿轮轴(9)从管状部分(12)部分地突出;和环形密封构件(32),其布置在管状配装构件(31)的径向内侧。管状配装构件(31)包括覆盖件侧配装部分(54)、覆盖件侧夹持部分(55)以及覆盖部分(56)。覆盖部分(56)设置有开口(61)。开口(61)设置成使得环形密封构件(32)在以下状态下暴露于外部:在配装长度为预定长度时管状配装构件(31)与管状部分(12)的配装完成的状态且齿条壳体(5)未安装在车辆上的状态,配装长度为覆盖件侧配装部分(54)的配装至壳体侧配装部分(21)的那部分的长度。
