<p>A shaft coupling includes a shaft (1) with a circumferential groove (2) near one end, a shaft receiving member (3) and a resiliently loaded shaft retention member (4) in the shaft receiving member (3). The shaft retention member (4) can be reciprocated in an elongate slot with or against the resilient bias so that upon insertion of the shaft in the shaft receiving member the shaft retention member (4) snaps into engagement with the groove (2) in the shaft (1). Any tendency to draw the shaft out of the shaft receiving member causes the shaft retention member to bed more firmly in the groove (2). In an alternative arrangement, the shaft retention member can be a torsion spring (9) fitted about a clamping bold (4), with one end (9A) of the spring engaging in the groove (2) of the shaft. The shaft (1) can be a vehicle steering column shaft and the shaft receiving member (3) can be a yoke of a universal joint.</p> |
