Claim 9:
10. The cart according to claim 1, further comprising:
a second driving wheel;
a second motor configured to rotate the second driving wheel;
a second motor drive circuit configured to drive the second motor;
a second motor brake electronic circuit configured to electrically brake the second motor; and
a second temperature sensor configured to detect a temperature of the second motor brake electronic circuit,
wherein
the control device is configured to control the second motor via the second motor drive circuit and the second motor brake electronic circuit so that a travelling speed of the cart becomes equal to or lower than the upper limit travelling speed, and
when the upper limit travelling speed is the first upper limit travelling speed and the temperature detected by the second temperature sensor exceeds the first predetermined temperature, the control device is configured to change the upper limit travelling speed to the second upper limit travelling speed.
