Abstract
A gear shift device for motor vehicles in which a fluid pressure production unit is arranged between a gear shift mechanism and a damper device and is connected directly with a drive input member. In the damper device for the gear shift device, the gear shift mechanism is connected through a first output member to the drive input member. The fluid pressure production unit is simultaneously connected to the input member through a second output member. Therefore, the torsional rigidity of the damper device can be set small enough to restrain the neutral noise associated with gear shift devices.
