The present invention relates to an electric power steering apparatus. The electric power steering apparatus includes: a rack housing including a sliding recess that is formed between a motor coupling hole in which a motor pulley is mounted and a ball nut coupling hole in which a nut pulley is mounted, the sliding recess being formed to extend in a direction perpendicular to a longitudinal direction where a belt is mounted; and a tension adjusting member including a central shaft one end of which is inserted into the sliding recess, a connection member coupled to another end of the central shaft, a pair of rollers coupled to opposite ends of the connection member to tighten opposite sides of an outer peripheral face of the belt, the central shaft being slid along the sliding recess to adjust the tension of the belt.

A system and method capable of detecting damage in a belt before catastrophic failure of the belt occurs. The system includes a belt having at least a first conductive component and/or at least a first dielectric component, and one or more pulleys to which the belt is mounted. At least a first of the pulleys has at least one conductive component that, in combination with the first conductive component or the first dielectric component of the belt, defines an electrical element. At least a portion of the electrical element is located within the belt so as to be physically responsive to transitory and permanent distortions of the belt resulting from extrinsic and/or intrinsic sources. Electrical potential is applied through the electrical element so as to generate an electrical signal from the electrical element corresponding to a physical response of the belt to a transitory and/or permanent distortion.

An auto tensioner is mounted on a rotating shaft of an engine auxiliary device rotating about the rotating shaft by a power transmitted through a power transmission belt. The auto tensioner pivots about a pivot shaft. The auto tensioner has one side rotatably fastened to the pivot shaft and another side fastened to a driving member, and pivots about the pivot shaft in accordance with an operation of the driving member
