Selector device for an automatic transmission system provided with

Abstract

In a selector device for an automatic transmission system, a rotatable member is supported by a first pivot shaft, and a selector lever is tiltably supported by the rotatable member by a second pivot shaft extending substantially perpendicularly to the first pivot shaft. A base end of the selector lever is bifurcated into a pair of engagement claws, and a checker cam is positioned in a gap defined between the engagement claws. A slide member can be slid into between the checker cam and the associated engagement claw to prevent the tilting movement of the selector lever. Thus, the slide member which is typically associated with a shift lock mechanism can prevent the tilting movement of the selector lever and, hence, the shifting of the selector lever from the P range position. Because the force applied to the selector lever is supported by the slide member as a compressive load, no substantial stress is applied to the actuator or the linkage provided between the actuator and the slide member. Therefore, various component parts forming the shift lock mechanism or otherwise associated with the movement of the slide member are not subjected to any large stress, and may consist of relatively small members.
