To travel into a narrow corridor and an elavator by reducing a turning radius of a carrier car and reducing a travel width by bringing a driver's seat into close contact with the patient side, by enabling travel even in a narrow passage by arranging the driver's seat on the side of a patient lying on his back.

A carrier car has a driver's seat on the side of a patient 2, and has a travel driving part and a driving wheel 5 uner a steering wheel 4. The carrier car is advanced and retreated by driving the driving wheel 5 by a battery. The direction of the carrier car is changed by changing the direction of the driving wheel 5. A turning radius is the sum of radiuses R1, R2 with a midpoint of two driven wheels 7 as the center. When traveling in the quiet hospital, travel by the battery is particularly effective from the viewpoint of noise and an offensive smell, and safe travel can be performed by installing an obstacle detector. When pulling out a bed part, the bed part can be easily pulled out of the carrier car since a roller is arranged on a frame 1.
