    • PROBLEM TO BE SOLVED: To make a transmission ratio steplessly variable without moving an endless flexible body itself in the transverse direction as well as to aim at a low-unit cost of production. SOLUTION: Plural pieces of arm pins 31 freely slidden in the radial direction each are installed in both driving and driven rotators 1 and 2. A tip of this arm pin 31 is inserted into a guide groove 16 formed on the surface of a cone 15. When this cone 15 is slidden in the axial direction, the arm pin 31 slides outward or inward. The cone 15 of the driven rotator 2 simultaneously slides in reverse to the sliding direction of the cone 15 of the driving rotator 1. Each bearing 34 rotating in only one direction is attached to these arm pins 31, and torque in the driving rotator 1 is transmitted to the driven rotator 2 by a timing belt 3. The arm pins 31 are slidden in the radial direction by both the cones 15 sliding in reverse with each other, and one side expands its diameter but the other side contracts respectively, whereby a transmission ratio is made variable in a stepless manner.
