Abstract:

A rack shaft support device includes: a rack shaft support member that is accommodated inside a retention hole formed in a housing so as to slide in an axial direction of the retention hole, and slidably supports a rack shaft; a sealing member fixed to an inlet port of the retention hole; an intermediate member that is interposed between the rack shaft support member and the sealing member; a torsion spring that couples the sealing member and the intermediate member; a cam mechanism that converts a rotational force of the intermediate member induced by untwisting of the torsion spring to a force by which the intermediate member pushes the rack shaft support member; an opposing portion that opposes a rear surface of the rack shaft support member; and an annular elastic member that is interposed between the rear surface of the rack shaft support member and the opposing portion.
