<p>PURPOSE:To maintain good running feeling by providing a flat characteristics part at a part of shaft output characteristics to the rotational speed of a vehicle driving. CONSTITUTION:A flat characteristics part is formed at a part of shaft output characteristics to the rotational speed of a vehicle driving motor 18. Even if the frictional force of the belt 46 of a belt type non-stage transmission 53 changes with the passage of time or the like, a vehicle (rear wheel WR) is driven by a certain shaft output in the rotational speed of the vehicle driving motor 18 to the flat characteristics part. If the frictional force of the belt 46 of the belt type non-stage transmission 53 changes with the passage of time or the like, the rotational speed of the vehicle driving motor 18 whose rotational speed is changed steplessly changes, however, the vehicle (rear wheel WR) is driven by a certain shaft output in the rotational speed range of the vehicle driving motor 18 whose rotational speed is changed steplessly regardless of a change in rotational speed of the vehicle driving motor. It is thus possible to maintain good riding feeling during driving.</p> |
