ABSTRACT:
An improved manually operable gearshift mechanism includes a support of sheet metal construction and a gearshift selector mounted on the support by a ball and socket arrangement for pivotal movement about first and second orthogonal axes. The gearshift selector is pivotal to a plurality of positions relative to the support to position a pair of gearshifting cables in positions corresponding to selectable transmission gears. The positioning of one of the gearshifting cables is achieved by a bellcrank pivotally mounted on the support and displaceable by a pin extending from the ball and displaceable about the second axis with the gearshift selector. Positioning of the other gearshifting cable is achieved by a link forming an extension of the gearshift selector below the first and second axes and which link is pivotal with the gearshift selector about the first axis. The link is pivotally interconnected with the gearshift selector so that the cable attached to the link is maintained substantially against lateral displacement during pivotal movement of the gearshift selector about the second axis.
