Abstract:
A rack shaft supporting device includes a support yoke, a plug that closes the other opening of an accommodation chamber, a ball screw mechanism between the support yoke and the plug, and a torsion urging member between the ball screw mechanism and the plug. The ball screw mechanism includes: a first threaded portion in which a first thread groove is formed; a second threaded portion in which a second thread groove is formed; and balls arranged in a rolling path formed of the first thread groove and the second thread groove. The torsion urging member rotates the second threaded portion relative to the plug and moves the second threaded portion toward the support yoke.
