Abstract
A shifting apparatus for a transmission of a vehicle comprising a shift lever operable left and right for travel to selection positions and front and rear for shifting gears, the shift lever being shiftable in one of the selection positions between a forward gear position and a reverse gear position. A projection is movable with the shift lever vertically in the selection operation and horizontally in the shift operation. A pivotable lock member is positioned in the vertical path of travel of the projection and the lock member and projection are provided with cam surfaces such that the lock member is pivoted, when the projection is moved, from a neutral position to an inoperative position. The lock member is held in its neutral position by a spring and in the inoperative position the shift lever is movable to the forward gear position and to the reverse gear position. When the projection is moved to the selection position, the cam surfaces are cooperatively engaged to pivotably move the lock member to its inoperative position and if the shift lever should then be moved to the forward gear position, the lock member is then pivotably moved by the spring to its neutral position at whi…
