12) The spherical center (14) of the spherical surface (3) contacts orthogonally at one point with a perfect circle (13) located above.
There are three requirements for looking up with the upper line as the supporting axis line (15). In addition, the perfect circle (16) of O in the example is the one shown in FIGS. The one shown in FIGS. 4 and 5 is located on the top surface (17).
), but the lower surface (18),
Furthermore, the passive rotating body (1) may be formed into a cavity and positioned on the inner peripheral surface of the cavity.
また、前記○の曲線（１０）が俯仰する機構は、第１〜

及びモータ（７）とから構成されている。In addition, the mechanism by which the ○ curve (10) looks upward is the first to
As shown in Fig. 3, a fixed arm (19) is fixed to a support stand (not shown), and a fixed arm (19) extends from the fixed arm (19) toward the passive rotating body (1) while being biased by a spring (20). A support arm (21) and a supporting arm (21) having the support axis (1)
5) a swinging arm (22) pivotally supported on the top and extending from the joint (5), and the pivoting shaft (6);
and a motor (7).

によりその曲線（１０）が俯仰するようにしである。By raising and lowering the motor (7), the rotating shaft (6) is connected to the pivot support (23) of the support arm (21).
The driving body (2) is lifted up and down as a fulcrum, and the curve (10) is made to go up and down as the driving body (2) is lifted up and down accordingly.

よシ受動回転体（１）や駆動体（２）が磨り減った場合
にも、両者が適確に接触するようにした為である。Further, the curve (10) of the driving body (2) is always pressed and brought into contact with the perfect circle (13) of the passive rotating body (1) due to the biasing force of the support arm (21). This is to ensure that even if the passive rotating body (1) and the driving body (2) are worn out due to contact rotation, they will come into proper contact with each other.
次にこの発明に係る無段変速装置の作用効果について説
明する。Next, the effects of the continuously variable transmission according to the present invention will be explained.
第１〜２図において駆動体（２）の球面（６）を前記中
心線を中心軸線（４）として一定速度で回動させると、
受動回転体（１）は一定速度で回転する。In FIGS. 1 and 2, when the spherical surface (6) of the driving body (2) is rotated at a constant speed with the center line as the center axis (4),
The passive rotating body (1) rotates at a constant speed.
この受動回転体（１）の回転速度は前記一点を通る駆動
体（２）の小円周の距離（２４）に対応する。The rotation speed of this passive rotating body (1) corresponds to the distance (24) of the small circumference of the driving body (2) passing through the one point.
そして、第３図に示すように駆動体（２）の曲線（１０
）を俯仰して前記小円よシ径の大きい小円（２５）が受
動回転体（１）の正円（１３）に接触するようにすれば
、この径の大きい小円周の距離（２６）に対応して受動
回転体（１）は回転し回転速度が増す。Then, as shown in FIG. 3, the curve (10
) so that the small circle (25) with a larger diameter than the small circle contacts the perfect circle (13) of the passive rotating body (1), the distance of the small circle with a large diameter (26 ), the passive rotating body (1) rotates and its rotational speed increases.
また、駆動体（２）の曲線（１０）を前述とは逆に俯仰
させれば受動回転体（１）の回転速度は減する。Furthermore, if the curve (10) of the driving body (2) is raised or lowered in the opposite manner to the above, the rotational speed of the passive rotating body (1) is reduced.
この受動回転体（１）の変速の際、駆動体（２）の曲線
（１０）は、前記第一の点（８）と第二の点（９）とを

俯仰に限らず常に同一距離（２７）を保つことになり、
受動回転体（１）の変速は駆動体（２）の曲線（１０）
の俯仰によシ滑らかに連続的に行われる。When changing the speed of this passive rotating body (1), the curve (10) of the driving body (2) is a line connecting the first point (8) and the second point (9) on the spherical surface (3). , contact orthogonally at one point with the perfect circle (13) of the passive rotating body (1), and look up with a line on the spherical center (14) of the spherical surface (3) as the supporting axis (15). Therefore, the same distance (27) is always maintained between the point where the curve (10) touches the perfect circle (13) and the center of the ball (14), regardless of the elevation of the curve (10).
The speed change of the passive rotating body (1) follows the curve (10) of the driving body (2).
This is done smoothly and continuously as the person looks up and down.

きるものである。Therefore, according to the continuously variable transmission according to the present invention, it is possible to continuously change gears by a movement different from that of conventional friction wheel type transmissions, that is, movement of the driving body (2) by raising and lowering the curve (10). Therefore, it can be optimally used in cases where it would be difficult to move a conventional transmission of this type due to space constraints.
