Abstract

A rack-and-pinion steering device (1) is provided with: a pinion (2) rotatable in an R-direction; a rack bar (4) that includes rack teeth (3) engaging the pinion (2) and that is linearly movable in a slide direction (A); a gear box (5) that supports the pinion (2) rotatably in the R-direction; a rack guide (6) that slidably supports the rack bar (4); and an elastic means (7) pushing the rack guide (6) toward the pinion (2).

Description

technical field [0001] The present invention relates to a rack guide for slidingly supporting a rack of a steering mechanism of a vehicle and a rack and pinion type steering device having the rack guide. Background technique [0002] As the steering gear device in the vehicle steering system, there is known a rack and pinion type steering device, in which the rack teeth of the rack mesh with the pinion at the distal end of the steering gear shaft in the gearbox, through Pinion and rack teeth, the rack is adapted to move in its axial direction by means of the rotation of the steering pinion shaft, and wherein, in the cylindrical part of the gearbox, a rack guide is provided on the tooth meshing with the pinion The rack portion opposed to the rack portion, thus, comes into slidable contact with the inner peripheral surface of the cylindrical portion, and a compression coil spring is inserted between the rack guide and the closing member to close the opening of the cylindrical ...
