Abstract: Disclosed is a back-lash eliminating mechanism in a screw-type driving device, in which a nut member is made flexible so that a screw member and the nut member can be disposed close to each other to thereby eliminate back-lash at the thread-engagement portion between the screw member and the nut member.

Abstract: A telescopic assembly includes a yoke supported for rotation on a stationary member, a shaft fitted in telescoping relation inside the yoke, rotatably supported by a movable bracket and capable of being reciprocated together with the movable bracket relative to the yoke, a screw rotatably retained by a stationary bracket, and a nut threadedly engaged with the screw and fixed to the movable bracket. When the screw is rotated, the nut provided on the movable bracket moves axially along the screw so that the movable bracket is moved toward or away from the stationary bracket. Hence, the shaft supported by the movable bracket is displaced axially forward or backward, depending upon the direction of screw rotation, relative to the yoke, thereby enabling the portion of the shaft projecting from the yoke to be adjusted in length.

Abstract: A safety system in an apparatus for adjusting attitudes of a tilt mechanism and a telescopic mechanism of a steering wheel by means of an electric motor. A change speed of attitude is monitored and, when the monitored result becomes less than a predetermined value, this is judged as the presence of overload, whereupon the direction of driving of the electric motor is reversed. When a time of the reverse operation or the number of strokes during the reverse operation reaches a predetermined value, the electric motor is set to stop. Attitude information is sampled with intervals of a predetermined time and, when a change amount of the attitude information is less than a predetermined value, this is judged as the presence of overload.

Abstract: In a tilt steering equipment including a main bracket mounted to a vehicle body; an upper bracket with a steering wheel, which is pivoted at the main bracket around a tilt center; and a driving means supported by the main bracket to tilt the upper bracket against the main bracket, the driving means in fixed to the main bracket and has a drive center spaced from the tilt center and an engaging pin which rotates around the drive center. The upper bracket has an engaging slotted hole in which the engaging pin is inserted. According to the tilt steering equipment of this invention, the drive center of the driving means is spaced from the tilt center. Therefore, it is easy to assemble the equipment with high accuracy and a smaller torque is enough to tilt the upper bracket to the main bracket.
