The invention discloses a device capable of achieving transverse shifting of a vehicle in a short distance, and particularly relates to a vehicle shifter in a ship cabin. The vehicle shifter in the ship cabin comprises a base and walking wheels arranged on the lower portion of the base, and further comprises a rail which is arranged on a deck and can allow the walking wheels to walk along the rail. A lifting jack used for supporting a vehicle chassis and a stepping motor which can drive the walking wheels to move are arranged on the base. Compared with the prior art, the vehicle shifter in the ship cabin has the advantages that the structural design is scientific and reasonable, good operability is achieved, the vehicle shifter is arranged at the corresponding position under the vehicle in use, the vehicle is jacked up under the function of the lifting jack, the walking wheels are driven by the stepping motor to roll on the linear rail, finally the vehicle is driven to transversely move, the short-distance transverse shifting of the vehicle in limited space is achieved, and the vehicle shifter is convenient to operate and especially suitable for being used on vehicle ferries and roll-on-roll-off ships.
