ABSTRACT:
A speed changing apparatus usable for a small car of the type including a bar-shaped steering handle and a speed changing gear mechanism having plural forward movement stages and a single backward movement stage is disclosed which is characterized in that shifting of speed changing gears to any one of the forward and backward movement stages is controlled by rotational displacement of a rotary type change cam and the apparatus is provided with a stopper mechanism adapted to limit rotation of the change cam within the range of an angle of rotation which is determined by the forward movement stages, wherein the stopper mechanism is released from the operative state by use of an actuating lever which is disposed on the handle, thereby assuring inhibition of an occurrence of damage or injury of gears due to incorrect handling by virtue of arrangement which is so made that shifting to the backward movement is achieved by very simple operation but shifting of any gear cannot be achieved unless handling is performed in the presence of a distinct intention for backward movement.
