Title: Parking lock mechanism for gate type automatic transmission shift control device

Abstract: A parking lock mechanism for a gate type automatic transmission shift control device is provided. In the mechanism, a pair of upper and lower projections are formed the inner surface of a side wall of a housing at a location adjacent a portion of a gate opening corresponding to a parking position of a shift lever. A radial projection is formed on the shift lever in such a manner as to be capable of passing through an interval between the upper and lower projections on the side wall. A lock lever is swingably mounted on the inner surface of the side wall so as to be capable of abutting upon the projections on the side wall when the shift lever is in the parking position, for thereby preventing further movement of the shift lever. By an actuator which is energized in response to depression of a brake pedal, the lock lever is moved away from the projections on the side wall into a position for allowing the projection of the shift lever to pass through the projections on the side wall and thereby allowing the shift lever to be shifted from the parking position to a park lock released position.
