る。In other words, when the driver and passenger are on board on the left and right sides, the center of gravity of the vehicle is approximately balanced in the center, but when only the driver and passenger are on board, the center of gravity is shifted to one side. As a result, driving stability deteriorates. In order to solve this problem, the steering handle is made swingable around the lower end of the steering shaft, and is placed on the side when two people are riding.
-Some devices are designed to be set at the center position when a passenger is on board. (Special Publication No. 37-8904, Special Publication No. 50-11
(Refer to Publication No. 661) However, since the above-mentioned conventional left-right movement structure of the steering handle is configured to swing around the lower end of the steering shaft, it can be set at the side position or at the center position. The orientation of the steering handle with respect to the direction of travel is different depending on when the vehicle is in use, resulting in a problem in that the steering feel is different when one person is on board and when two people are on board.
