<p>PURPOSE:To make a relative angle displacement detector and an actuator protectable from an obstruction, by setting them in the more upper part than linkage, altering rotation of a steering shaft, to which a handle bar is locked, to each steering angle of running wheels and in a position to be surrounded by a body frame. CONSTITUTION:A steering bracket 64 is tightly attached to the lower part of a steering shaft 60 where a handle bar 62 is locked to the upper end, and this bracket is connected by a steering knuckle arm and a tie rod unitized with a steering knuckle 28. Steering linkage 70 is constituted of the steering bracket 64, the steering knuckle arm, the tie rod, etc. In this case, a power asisting unit 72 is installed interposingly in the point midway in the steering shaft 60. This unit 72 is constituted of assembling a control valve 82 or a device detecting each relative angle displacement of both upper and lower steering shafts 60a and 60b and a power cylinder 84 as an actuator as one body, and thus unit 72 is set up in the more upper part than the linkage 70 and in a position being surrounded at the front and both sides by a body frame.</p> |
