Claims

[Scope of utility model registration request]

A pair of bearing parts, in which a pinion shaft integral with a pinion which is disposed in a gear box with a rack in between and engages with the rack, is inserted, can be moved only in the axial direction of the rack through an elongated hole formed in the gear box. A steering torque detecting means measures the amount of movement of the pinion shaft within the range of play of the bearing portion, detects steering wheel steering torque, and generates power assist based on the detected signal. A rack-and-pinion power steering device characterized by:
