Abstract
In a shift mechanism for a change-speed gearing in a power transmission unit, a spring loaded movable element in the form of a piston is slidably disposed within a reverse shift head member to be pushed inwardly by engagement with a shift-and-select lever, and a stopper pin is integral with the movable element and movable between a first position in which the movable element is apart from the lever and a second position in which the movable element is engaged with the lever, the stopper pin being arranged to be located at its outer end adjacent to a stationary member to restrict unexpected forward movement of a reverse fork shaft in its first position and to be aligned with a recessed portion of the stationary member to permit the forward movement of the reverse fork shaft in its second position for establishment of a reverse gear train.
