Title:
伸縮自在シャフトおよび車両操舵用伸縮自在シャフト
Document Type and Number:
Japanese Patent JP4930756
Kind Code:
B2
Abstract:
A telescopic shaft (5) has an inner shaft (12) and a 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 plurality of balls (14) are aligned between respective raceway grooves (15; 16) of the inner shaft (12) and the outer shaft (13). Limiting mechanisms (20A; 20B) are provided that limit the amount of relative rotation to not more than a predetermined amount 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) engageable 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) that are adjacent to the raceway grooves (15; 16) of the inner shaft (12) and the outer shaft (13), respectively.
