TRAVELING CAR

A traveling car includes a car body and a driver. The driver has a motor that is attached to the car body, a drive wheel, a support that supports the drive wheel, and a transmission that transmits rotary drive force to the drive wheel. The support has a holder that rotatably supports the drive wheel and is attached to the car body so as to rotate about a rotation axis M extending in the horizontal direction. The transmission has an output pulley that is coupled to the motor and is located on the car body, an input pulley that is coupled to the drive wheel and is located on the holder, and a belt wound around the output pulley and the input pulley. The rotation axis M is located coaxial with the output pulley.
