Abstract
A column shift lever device operatively connected to an automatic transmission of a motor vehicle and supported by a steering column which has a tiltable upper portion supporting a steering wheel. The column shift lever device includes a shift lever; a tubular control shaft having at least one axially extending elongate hole formed therethrough; an inner shaft accomodated within the tubular control shaft, which has a fastener member protruding therefrom through the above-indicated at least one elongate hole, so that the inner shaft is axially movable relative to and rotatable with the control shaft; a stationary cylindrical outer casing for rotatably supporting the control shaft at a portion thereof below the tiltable upper portion; a detent device having a detent pin for locking the shift lever in one of a plurality of shift positions corresponding to a plurality of operating positions of the automatic transmission. The detent means includes a detent support sleeve which supports the detent pin and which is connected to the inner shaft through the fastener member. The column shift lever further includes a splined engaging device provided between an outer circumference of the control shaft and an inner circumference of the detent support sleeve, for permitting a relative axial movement and a concurrent rotation of the control shaft and the detent support sleeve.
