Abstract
A detent structure for a hydraulic automatic transmission system, in which a control shaft rotatably supported by a casing of the automatic transmission system carries a detent cam plate integrally attached thereto and radially extending therefrom. The free end of the detent cam plate is provided with a cam profile defining a plurality of depressions corresponding to different shift positions of the automatic transmission system in cooperation with a cam follower urged against the cam profile by a tension coil spring extending across the control shaft and a detent arm carrying the cam follower. Therefore, no extra radial load is applied to the opening of the transmission casing rotatably supporting the control shaft, and, therefore, the force required to rotate the control shaft is not affected by the force urging the cam follower against the cam profile of the detent cam plate securely attached to the control shaft.
