Abstract: A cam follower includes an oval rotational body which is rotationally supported on a fixed pin, and in which an outer circumferential shape thereof is an oval, a long axis of the oval is longer than a width of the cam groove, and a short axis of the oval is shorter than the width of the cam groove, the oval rotational body being biased and being rotated by a biasing spring in one direction about the fixed pin. As a consequence, when a steering wheel is in a neutral position, the outer circumferential surface of the cam follower comes into contact with both side surfaces of the cam groove in the width direction of the cam groove and gaps therebetween can be eliminated. As a result, neutral stability of the steering wheel and steering feeling during straightforward traveling are improved.

When the steering gear box has reached a stroke end, and the assist current or the steering torque is smaller than a predetermined threshold value, the overload preventing control is conducted using a threshold value that is less than the predetermined threshold value.

Abstract: Attachments for a manual wheelchair are provided for navigating a wheelchair over obstacles and uneven terrain, such as a typical curb on a street. The attachments provide for regulating the movement of the wheelchair as the wheelchair descends the curb and to prevent the wheelchair from flipping over during such movement. The attachments include a front caster wheel slider assembly on each side of the wheelchair, a follower wheel assembly and a track belt damping bar. The front caster wheel slider assembly includes a piston that will quickly push the front caster wheels down after they roll over the top edge of the curb. The follower wheel assembly acts as a sensor that will release the piston in the assembly after the front caster wheels roll over the top edge of the curb. As the back wheels of the wheelchair roll over and down the curb, the track belt damping bar slows the descent of the wheelchair.
