摘要： (1) Various gear states are selected by movement of a shift lever 2 in a longitudinal shift path 13 and the gear stage is automatically shifted from starting to the maximum gear stage in an automatic speed change position D, so that an operator can run a vehicle with increased safety and easy operation without operation of the shift lever 2. (2) When a push button switch 3 provided in the shift lever 1 is pressed during the automatic speed change running, the gear stage during the running is fixed, so that inadvertent automatic shift is prevented and an optimum speed stage is maintained when the work load on the vehicle's engine changes, for example when the vehicle encounters a slope or a change in load during in operation. (3) When the gear stage is fixed in the automatic speed change position D and the shift lever 2 is transversely moved in the transverse shift path 14, the operator can vary the stages while varying one stage a time with the operator's will. That is, the manual speed change or transmission can be selected regardless of the automatic speed change state. The operator can switch the transmission state to the automatic transmission state or the manual transmission state in accordance with various running states and operation states to thereby improve the operation efficiency of the operation vehicle.

摘要翻译： （1）通过变速杆2在纵向移动路径13中的移动来选择各种齿轮状态，并且齿轮级在自动变速位置D中自动从开始变速到最大档位，使得操作者可以运行 增加安全性且操作简单，无需换档杆2的操作。（2）当在自动变速运行期间按下设置在变速杆1中的按钮开关3时，在行驶期间的档位被固定，使得 当车辆的发动机的工作负荷变化时，例如当车辆在操作期间遇到斜坡或负载变化时，防止意外的自动变速，并且保持最佳的速度级。 （3）当齿轮级固定在自动变速位置D中并且换档杆2在横向移动路径14中横向移动时，操作者可以根据操作人员的意愿改变一个时间段的阶段。 也就是说，无论自动变速状态如何，都可以选择手动变速或变速。 操作员可以根据各种运行状态和操作状态将传动状态切换到自动变速器状态或手动变速器状态，从而提高操作车辆的运转效率。
