PURPOSE:To give sufficient supporting strength and positioning accuracy to a belt strip anchor so that the anchor can be stably installed to the mounting part by forming the guide rail parts of curved adjuster rails integrally with rack teeth, and holding a screw slider in a slide anchor and keeping it on a drive shaft. CONSTITUTION:Adjuster rails 11 of U-shaped cross section are formed in a shape curved along the mounting part of a vehicle body, and external flange- shaped guide rail parts 15 and a pair of rack teeth 16 are formed respectively integrally with the U-shaped open sides and both side walls of the adjuster rails. A slide anchor 18 is installed so that it holds and strides over the guide rail parts 15 of the adjuster rails 11, further holds a screw slider 30 provided with a worm 42 mating with the rack teeth 16 of the adjuster rails 11 rotatably in the slide anchor 18, and keeps the screw slider 30 on a flexible, motor-driven drive shaft 40 so that it can rotate integrally with the drive shaft and is slidable in the axial direction. |
