Abstract

An electrically operated power steering apparatus has an electric motor (10) disposed parallel to a rack shaft (3). The system is designed such that the motor can be installed in any angle around a rack housing (1) of small diameter. This permits easy installation and flexibility of design. The apparatus is also designed to accommodate off-the-shelf electric motors that are already commercially available so as to eliminate the need to customize an electric motor for each application.
