• a front wheel supporting member configured to rotatably support the front wheel;
• a rear wheel supporting member configured to rotatably support the rear wheel;
• an adjusting mechanism configured to adjust a wheel base length between the front wheel and the rear wheel by changing a relative position of the front wheel supporting member and the rear wheel supporting member;
• and
• a driving unit configured to drive at least one of the front wheel and rear wheel, wherein the wheel base length adjusted by the adjusting mechanism is associated with a speed of the traveling apparatus achieved by driving the driving unit in such a way that the longer the wheel base length, the greater the speed becomes, and when one of values of the wheel base length and the speed is changed by an operation of the user, the other one of the values is controlled to be a value associated with the changed one of the values.
