Abstract:
A shock absorbing device for a rack and pinion type steering device includes a rack shaft, a rack housing, a stopper portion formed in an end part of the rack shaft, a stopper engaging portion provided on the rack housing to define a stroke end position for the rack shaft by engaging the stopper portion, a stepped portion formed on the rack shaft, a shoulder portion formed in an enlarged diameter portion of the rack housing, and a cylindrical elastic member fitted on the rack shaft such that the elastic member is pressed in the axial direction of the rack shaft by the stepped portion and the shoulder portion. The elastic member is formed with grooves on each of an outer circumferential surface and an inner circumferential surface thereof. Such shock absorbing device for a rack and pinion type steering device has a high shock absorbing capability.
