摘要： A steering shaft support structure for an all terrain vehicle in which both forces of push and pull applied to an EPS unit are reduced when a load is applied to handlebars. The structure includes a steering shaft rotatably supported by a body frame and handlebars attached to the steering shaft. The EPS unit is also supported by the body frame. Two sets of adjustable joints are interposed between the steering shaft and the EPS unit in such a manner that their axes are shiftable. With this, if a load is applied to the handlebars, the adjustable joint associated with the steering shaft follows the inclination of the steering shaft, so that the connection point (swing point) of the adjustable joint associated with the EPS unit does not shift. This reduces both forces of push and pull applied to the EPS unit.
摘要翻译：一种用于全地形车辆的转向轴支撑结构，其中当将负载施加到车把时，其中施加到EPS单元的推力和牵引力都减小。该结构包括由主体框架可旋转地支撑的转向轴和附接到转向轴的车把。 EPS单元也由车身框架支撑。两组可调接头插入转向轴和EPS单元之间，使其轴线是可移动的。由此，如果向车把施加负载，则与转向轴相关联的可调接头跟随转向轴的倾斜，使得与EPS单元相关联的可调节接头的连接点（摆动点）不移动。这减少了施加到EPS单元的推拉力和拉力。

摘要： A structure for attaching an electrically-operated power steering apparatus for a vehicle. The structure includes a body frame, more specifically, sub slant frames having respective motor brackets for supporting an actuator unit. The motor brackets have bolts that fasten the actuator unit, and the bolts extend perpendicularly to a steering shaft. With this configuration, the structure is not affected by a manufacturing error of a body frame and other parts of the vehicle. Further, the structure takes account of a direction in which fastening means is tightened.
