ABSTRACT:
A range switching device is provided that is capable of selecting a running range accurately using a simple configuration and control. The range switching device includes a conversion mechanism which, in turn, includes a ball screw shaft, a ball nut, and other members. The ball nut is connected to a spool through an arm member, a range control shaft, and a detent lever. The spool is moved into a specified selection region among a plurality of selection regions by the conversion mechanism and the arm member. Then, the spool is more precisely moved to a selection position within the specified selection region by the detent mechanism and positioned and held thereat.
