PURPOSE:To arrange so as to obtain a compact but powerful transmission by changing a speed change gear ratio through changing the contact point of two rotational bodies which contact each other. CONSTITUTION:A motor 2 put in a case 1 is equipped at the lower part with a wheel which is designed to be movable on a lower-part guide rail 8. The motor 2 is equipped with shafts for guiding on both sides of an output shaft side and moves on an upper-part guide rail 7 and also is guided by the long hole of the center portion of a speed change lever 4. A first-moving wheel 3 is fitted to the output shaft of the motor 2 and rotates. The output shaft 5 is made to be cylindrical at the lower part and has a follower 6 made of hard rubber at the tip thereof. The follower wheel 6 comes into contact with the first-moving wheel 3 and rotates and the output shaft 5 rotates. A speed change lever 4 has the lower end supported by the case 1, and by moving this, the motor 2 is moved forward and backward, and a predetermined speed change gear ratio is obtained.
