Patent ID: 8443689

Claim:
A rack shaft support device comprising: a rack shaft support member that is accommodated inside a retention hole formed in a housing so as to be able 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 and can rotate about a central axial line of the retention hole; a torsion spring that couples the intermediate member so that torque is transmitted to the intermediate member; a torsion amount adjusting member that is attached to the sealing member in such a manner that a position of the torsion amount adjusting member with respect to the sealing member is adjustable and adjusts a torsion amount of the torsion spring; and a cam mechanism that converts a rotation force of the intermediate member induced by untwisting of the torsion spring into a force by which the intermediate member pushes the rack shaft support member, wherein a threaded hole is provided in the intermediate member, a fixing jig insertion hole is provided in the sealing member, the threaded hole and the fixing jig insertion hole are provided to be in a row on the same axial line when the intermediate member is in a predetermined rotation position, and the sealing member and the intermediate member can be fixed to each other by using a fixing jig screwed in the threaded hole through the fixing jig insertion hole.
