PURPOSE:To increase the capacity by drive coupling between input cone discs and between output cone discs of respective transmission units each other thereby enabling relative displacement in the axial direction and performing synchronous displacement of respective transmission units. CONSTITUTION:An input shaft 1 is coupled coaxially with a drive shaft 5, and a drive plate 6 and thrust plate 7 are coupled to the opposite ends thereof. Transmission units 3, 4 are provided between them. One input cone disc 9 is secured to a hollow coupling shaft 8 provided rotatably on the drive shaft 5 while the other input cone disc 10 is spline coupled to the hollow coupling shaft 8. Output discs 11, 12 of both units are coupled to a hollow output shaft 16 which is coaxial with the hollow coupling shaft 8. When a loading cam function to separate the drive plate 6 and the input cone disc 10, the disc 10 is spline coupled while the disc 9 is pushed by the thrust plate thereby the input discs 9, 10 approaches closely each other.
