ABSTRACT:
A shift lever control device is disclosed. A cranked guide slot is defined along which a shift lever is slidably moved. The guide slot includes at least one elongate part and a shorter terminal part which extends in a given direction perpendicular to the elongate part. The shift lever is pivotal in a universal direction and biased in a direction opposite to the given direction. A pivot latch member is located near a joint portion between the elongate part and the shorter terminal part of the guide slot. The pivot latch member has a guide recess formed therein and is pivotal between a first given position wherein an enclosed space is defined by the shorter terminal part of the cranked guide slot and the guide recess of the pivot latch member and a second given position wherein the guide recess of the latch member is open to the elongate part of the cranked guide slot. A check mechanism is employed for making the pivotal movement of the latch member to the first and second given positions in a snap action manner. The check mechanism includes a cam member secured to the latch member and having a cam surface with rounded depressions, elastomeric members respectively disposed in the rounded depressions, and a detent member held by a stationary member and resiliently pressed against the cam surface of the cam member.
