Abstract: The cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to drive the motor; a control device configured to control the motor via the motor drive circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed; and an operation member arranged on the cart and configured to receive an operation by a user. The cart may be configured to operate in a manual mode where the motor is driven when the operation member is on and the motor is stopped when the operation member is off, and in an automatic mode were the motor is driven regardless of whether the operation member is on or off. The upper limit travelling speed in the automatic mode may be set lower than the upper limit travelling speed in the manual mode.
