摘要： A telescopic shaft (5) has an inner shaft (12) and tubular outer shaft (13) that are fitted to each other so that they can move relative to each other in the axial direction and that they can transmit torque to each other. A row of balls (14) is placed in respective raceway grooves (15; 16) of the inner shaft (12) and the outer shaft (13). Limiting mechanisms (20A; 20B) are provided in the telescopic shaft (5), and the mechanisms limit the amount of relative rotation of the inner shaft (12) and the outer shaft (13) when a ball (14) comes off the raceway grooves (15; 16). The limiting mechanisms (20A; 20B) include a pair of engagement sections (21, 22; 23, 24) engaging with each other in a circumferential direction (C1). The engagement sections (21, 22; 23, 24) are provided at ridges (25, 26) and recesses (27, 28), and the ridges (25, 26) and recesses (27, 28) are adjacent to the raceway grooves (15; 16) of the inner shaft (12) and the outer shaft (13), respectively.

摘要： An extendable shaft (5), comprising an inner shaft (12) and a tubular outer shaft (13) fitted axially relatively movable so that a torque can be transmitted to each other. A plurality of balls (14) aligned are interposed between the corresponding raceway grooves (15, 16) of the inner shaft (12) and the outer shaft (13). Each of the raceway grooves (15, 16) has a predetermined cross section. As a result, the contact angle (A1) of the balls (14) to the raceway grooves (15, 16) is zero at no-load and can be gradually increased according to an increase in load torque.

摘要： There is provided a collapsible steering apparatus, which includes a steering column having a movable part capable of moving upon collision of a vehicle. The main part of a bracket is fixed to the movable part. Extended pieces are extended from the main part, and each extended piece is folded back into a U shape to superimpose the extension end of the bent extended piece on the main part. A fixing member is inserted into each insertion hole of the main part and of the extension end of the extended piece, and is fixed to a vehicle body member. As a result, the extension end is fixed to the vehicle body member. The insertion hole of the main part includes an open part for allowing the fixing member to come off upon collision. Upon collision, the main part of the bracket and the base end of the extended piece move along with the movable part. As a result, the base end and the extension end of the extended piece move relative to each other to deform the extended piece to absorb the impact of the collision.
