A four-joint link mechanism type continuously variable transmission equipped with a rotation radius adjustment mechanism capable of adjusting the radius of the rotary motion of the cam, wherein the rotation radius adjustment mechanism includes a cam disk eccentrically provided on the input shaft, Rotation provided eccentrically with respect to the cam disk. Comprising a disc and a plurality of gears rotatably disposed against the input shaft at the radially outer side of said input shaft, said a rotating disk, receiving hole for receiving the input shaft and the cam disc is provided is, the plurality of gears are arranged so as to sandwich the cam disc, two of said gears adjacent to each other across the cam disk, a pair of teeth on the rotating disk is formed at intervals in the axial direction by meshing parts and each rotation of one gear of the two said pinions adjacent across the cam disc, through the rotary disk, characterized in that it is transmitted to the other gear.
Moreover, the gear of both aspects of this invention can be comprised with the pinion rotatably supported by the input shaft, and a tooth | gear part can be comprised with the internal tooth formed in the receiving hole of the rotating disk.

本発明によれば、ギヤを入力軸の径方向外方で入力軸に対して回転自在に配置させているため、入力軸やカムディスクに切欠孔を設けることなく、当該ギヤと回転ディスクの内歯とを噛み合わせることができる。また、当該ギヤは、隣接する２つの回転ディスクの歯部に夫々噛合しているため、回転ディスクがカムディスクに対して回転することにより一方の回転半径調節機構の入力軸側の回転運動の半径が変化すると、カムディスクの間に位置するギヤを介して隣接する回転半径調節機構も同様に入力軸側の回転運動の半径が変化する。従って、本発明によれば、上記のギヤ同士が連結されていなくても、各ギヤを回転させて回転半径調節機構の入力軸側の回転運動の半径を調節することができる。そして、従来のように入力軸とカムディスクとで構成される中空のカムシャフトにピニオンシャフトを挿入すると共に、カムシャフトに切欠孔を形成する必要がなく、カムシャフトの剛性を向上させることができる。 According to the present invention, since the gear is disposed so as to be rotatable with respect to the input shaft radially outward of the input shaft, the inner shaft of the gear and the rotating disc can be formed without providing a notch hole in the input shaft or the cam disk. Teeth can be engaged with each other. Further, since the gears are respectively meshed with the teeth of two adjacent rotating disks, the rotating disk rotates with respect to the cam disk, so that the radius of rotational motion on the input shaft side of one of the rotating radius adjusting mechanisms is increased. Changes, the radius of rotational motion on the input shaft side also changes in the adjacent turning radius adjusting mechanism via the gear located between the cam disks. Therefore, according to the present invention, even if the gears are not connected to each other, it is possible to adjust the radius of the rotational motion on the input shaft side of the rotational radius adjusting mechanism by rotating each gear . In addition, the pinion shaft is inserted into the hollow camshaft constituted by the input shaft and the cam disk as in the prior art, and it is not necessary to form a notch hole in the camshaft, thereby improving the rigidity of the camshaft. .
