Abstract
A shifter is equipped with a rack and a stopper. A transmission gear transmits power from an electric motor to the rack. A retention pin extends vertically downward from the transmission gear. When the shifter slides to an origin, the retention pin locks the stopper, which causes the electric motor to step out. On detecting the step-out of the electric motor, the position control device recognizes that the shifter has reached the origin (the reference position) and has been fixed at the position, thus setting the shifter position.
Claims17
A position control device for a slidably supported moving member, which controls a slide position of the moving member by powering the moving member,
- said position control device comprising:
- a first power transmission element provided at the moving member;
- a second power transmission element for transmitting power from a drive source to the first power transmission element;
- and
- a stopper provided at the moving member,
- wherein the second power transmission element is integrally equipped with a transmission part and a projection,
- the transmission part being directly connected with the first power transmission element and transmitting power from the drive source to the first power transmission element, and
- the projection locking the stopper and limiting a position of the stopper, and thus fixing the moving member at a predetermined slide position when the moving member slides closer to the second power transmission element and reaches the predetermined position.
