Document Type and Number:
WIPO Patent Application WO/2005/070744
Kind Code:
A1
Abstract:
A collapsible column for the steering of a vehicle installed in the steering column of the vehicle and having a male shaft and a female shaft non-rotatably and slidably fitted to each other, comprising torque transmission parts formed in the outer peripheral part of the male shaft and the inner peripheral part of the female shaft and coming into contact with each other in rotating for transmitting a torque and preload parts having rolling elements installed at positions different front those of the torque transmission parts between the outer peripheral part of the male shaft and the inner peripheral part of the female part and rolling when the male shaft and the female shaft are axially moved relative to each other and elastic bodies radially disposed adjacent to the rolling elements and providing preloads to the male shaft and the female shaft through the rolling elements. Where a rotating angle obtained by converting a clearance at the torque transmission part is A and a rotating angle obtained by converting the deformable amount of the elastic body at the preload part is B, these angles are set to the rotating angle A < rotating angle B when the torque is not transmitted.
