摘要： The present invention is directed to a gearshift unit for a transmission of a vehicle, the gearshift unit comprising a blocking mechanism for blocking a shift lever (2) from being moved to a shifting gate including the reverse gear, said blocking mechanism comprising a hollow shaft (4) mounted to be slidable along a longitudinal direction of the shift lever, wherein an annular protrusion (42) is projecting radially from the upper end of the hollow shaft, which annular protrusion (42) may be grasped to lift the hollow shaft upwards to a release position in which the shift lever is free to be moved to the shifting gate including the reverse gear, wherein a helical spring (20) is disposed within the hollow shaft and biasing it in downward direction to a blocking position in which a stop member of the hollow shaft blocks movement of the shift lever to the shifting gate including the reverse gear, wherein a spring holder (80) fixed with respect to the shift lever supports one end of the spring (20) which acts with its opposite end on the hollow shaft (4) to urge it downwards, characterized in that the spring holder (80) is provided with an elastic end stop (82) projecting radially with respect to the shift lever axis and extending into an opening (48) of the wall of the hollow shaft, which opening (48) is arranged such that a lower edge (50) of the opening contacts the end stop (82) when the hollow shaft approaches the release position to smoothly stop movement of the hollow shaft at the release position.
