TELESCOPABLE SHAFT AND STEERING DEVICE FOR VEHICLE

Title:

TELESCOPABLE SHAFT AND STEERING DEVICE FOR VEHICLE

Document Type and Number:

WIPO Patent Application WO/2007/040083

Kind Code:

A1

Abstract:

A telescopable shaft (5) has an inner shaft (12) and a tubular shaft (13) that are fitted to each other so as to be relatively movable in an axis direction (X1) and to be able to transmit torque between each other. A row of rolling bodies (14) is interposed between corresponding axial grooves (15, 16) of the inner shaft (12) and the outer shaft (13). A retaining member (17) moving together with the rolling balls (14) while retaining the balls (14) has a facing section (33) facing an end surface (121) of the inner shaft (12). As the telescopable shaft (5) telescopes in and out, the facing section (33) comes into contact with the end surface (121) of the inner shaft (12), and this limits the movement of the rolling bodies (14) in the axial direction (X1).
