Claims

[Claims for Utility Model Registration] (1) In the transmission system from the input shaft to the output shaft, a plurality of conical rotors are frictionally engaged with a small diameter transmission wheel, a large transmission wheel, and a speed change ring in a balanced manner, The rotation of the input shaft is transmitted to the small-diameter transmission wheel, and the rotation of the large-diameter transmission wheel or the speed change ring is transmitted to the output shaft, and the speed change is performed by moving the speed change ring in the axial direction, and the speed change range is 0 rotations. A friction continuously variable transmission that includes a forward rotation range and a reverse rotation range across the position, and a transmission that generates thrust according to the load torque of the output shaft to shift the gear ring to the low speed side in the forward rotation range and reverse rotation range. a first spring that receives the thrust of the thrust generating means during forward rotation; a second spring that receives the thrust of the thrust generating means during reverse rotation; and a first spring that receives the thrust of the thrust generating means during forward rotation; and a speed change operating means that urges each of the speed change rings toward a higher speed side through a second spring during rotation, wherein the speed change operation means biases the speed change ring from the 0 rotation position via the first spring during forward rotation. A first speed change operation means that biases the speed change ring toward the high speed side, and a second spring that biases the speed change ring from the 0 rotation position toward the high speed side during reverse rotation, and an interlock mechanism that biases the speed change ring from the 0 rotation position to the high speed side. 1. An automatic transmission device for a vehicle, characterized in that the automatic transmission device comprises a second speed change operation means associated with the second speed change operation means. (2) A first stopping means that prohibits the first spring from moving to the anti-high speed side beyond the initial position at no-load zero rotation during forward rotation, and a second spring that prohibits the second spring from moving to the opposite high-speed side during no-load zero rotation during forward rotation. 2. The automatic transmission for a vehicle according to claim 1, further comprising a second stopping means for prohibiting movement beyond the initial position during rotation to the opposite high speed side.
