Abstract There is disclosed a mechanism for stationarily supporting an operation panel mounted on a steeering wheel of a movable body. This mechanism includes two external gears between which said steering wheel is interposed, and two satellite gears resiliently urged toward the external gears. One of the external gears is stationary and the other has an operation panel secured thereto. Two satellite gears are rotated in the same direction and as a result, the operation panel is rotated in the opposite direction to that of the steering wheel and keeps substantially stationary. Further, there is disclosed a signal transmitting system for a radiotelephone in the movable body. A microphone is provided on the operation panel and a speaker unit is located at any position in the movable body. A duplex signal transmitting path having a howling control function is provided between the microphone and the speaker unit.
A steering apparatus comprising a first external gear fixed on a column cover positioned under the spoke of a steering wheel, the steering shaft of which passes through the first external gear and is freely rotatable therein, a second external gear rotatably supported on the upper end of the steering shaft which extends over the spoke of the steering wheel, an operation panel fixed on the upper surface of said second external gear, a rotating shaft located parallel to the steering shaft, satellite gears secured to the upper and lower ends of said rotating shaft and adapted to engage said first and second external gears, a rod which is pivotably supported at its one end on the spoke of the steering wheel and has at its other end a bearing for rotatably supporting the rotating shaft of the satellite gears, a coil spring which is secured at its one end to the spoke and hooked at its other end to the rod, said coil spring being wound around the rod so that the rod is urged toward the steering shaft, whereby the rotating shaft is resiliently urged to the steering shaft.
