Then, a centrifugal weight that pushes the movable sheave toward the fixed sheave by centrifugal force, a shift mechanism that is provided separately from the centrifugal weight and controls the axial movement of the movable sheave, the shift mechanism and the movable sheave, And a bearing that allows rotation of the movable sheave, and moves the movable sheave relative to the fixed sheave. A V-belt type continuously variable transmission which performs shift by changing the winding diameter of the V belt,
The movable sheave can be divided into a first sheave half having a cam surface and a second sheave half having the belt receiving surface, and between the first sheave half and the second sheave half. A boss having a diameter larger than that of the crankshaft and smaller than that of the first sheave half is provided, and the bearing is fitted to the boss.
The invention according to claim 3 is characterized in that the bearing is positioned by sandwiching both axial sides of the bearing between the first sheave half and the second sheave half.

請求項１、２に係る発明では、可動シーブを２分割することにより、分割された第１シーブ半体と第２シーブ半体との間に小径のボスを形成し、この小径のボスに軸受を嵌めるようにした。
従来よりも格段に小径の軸受が採用できるため、軸受の焼き付き防止およびコストダウンが図れると共に、変速機ケースの大型化が回避できる。
すなわち、本発明により、Ｖベルト式無段変速機の耐久性向上およびコストダウン並びにコンパクト化が図れる。
なお、可動シーブの外周面に軸受を嵌める従来構造のまま軸受を小径化すると、遠心ウエイトの作用が小さくなり、出力の大きなアクチュエータが必要となる。結果、アクチュエータのコストアップ及び大型化ならびに重量増加、更には燃費の悪化をも招く。
In the first and second aspects of the invention, the movable sheave is divided into two parts to form a small-diameter boss between the divided first sheave half and the second sheave half, and the small-diameter boss has a bearing. To fit.
Since a bearing having a much smaller diameter than before can be employed, it is possible to prevent the bearing from being seized and reduce the cost, and to avoid an increase in the size of the transmission case.
That is, according to the present invention, it is possible to improve the durability, reduce the cost, and make the size of the V belt type continuously variable transmission.
If the diameter of the bearing is reduced with the conventional structure in which the bearing is fitted to the outer peripheral surface of the movable sheave, the action of the centrifugal weight is reduced, and an actuator with a large output is required. As a result, the cost and size of the actuator are increased, the weight is increased, and the fuel consumption is also deteriorated.
請求項３に係る発明では、第１シーブ半体と第２シーブ半体により、軸受の軸方向両側面を挟むことで、軸受が位置決めされる。
スナップリングなどの止め具で軸受を固定する場合に比べ、本発明では、止め具挿入用の溝が不要であり、溝が不要であれば第１シーブ半体又は第２シーブ半体の大型化が回避できる。
したがって、本発明によれば、可動シーブの小型軽量化が図れる。
In the invention which concerns on Claim 3 , a bearing is positioned by pinching | interposing the axial direction both sides | surfaces of a bearing with a 1st sheave half body and a 2nd sheave half body.
Compared to the case where the bearing is fixed with a stopper such as a snap ring, the present invention does not require a groove for inserting the stopper, and if the groove is unnecessary, the first sheave half or the second sheave half is enlarged. Can be avoided.
Therefore, according to the present invention, the movable sheave can be reduced in size and weight.
請求項４に係る発明では、第１シーブ半体と第２シーブ半体とを、圧入結合により一体化する。
圧入結合であるから、締結ボルトなどが不要となり、軽量化及びコンパクト化が容易に図れる。
In the invention according to claim 4 , the first sheave half and the second sheave half are integrated by press-fitting.
Since it is a press-fit connection, a fastening bolt or the like is not necessary, and the weight and the size can be easily reduced.
請求項５に係る発明では、第１シーブ半体と第２シーブ半体とは、スプライン結合と圧入結合の組合せにより結合される。
スプライン結合でトルク（回転力）の伝達を行わせ、圧入結合により軸方向の位置決めを行わせる。圧入結合のみでトルク伝達と位置決めを行わせる場合に比較して、伝達トルク値を容易に高めることができる。
In the invention according to claim 5 , the first sheave half and the second sheave half are coupled by a combination of spline coupling and press-fit coupling.
Torque (rotational force) is transmitted by spline coupling, and axial positioning is performed by press-fitting coupling. Compared with the case where torque transmission and positioning are performed only by press-fitting coupling, the transmission torque value can be easily increased.
請求項６に係る発明では、圧入結合に係る圧入おす部が第１シーブ半体に設けられ、圧入めす部が第２シーブ半体に設けられる。
仮に、第１シーブ半体に圧入めす部を設けると、この圧入めす部より径外方にカム面を設けることになる。すると、第１シーブ半体の外径が増大し、可動シーブが大型になる。
この点、本発明では、第１シーブ半体に圧入おす部を設けたので、第１シーブ半体の外径が増大することはなく、可動シーブが大型になる心配はない。
In the invention which concerns on Claim 6 , the press fit male part which concerns on press fit coupling | bonding is provided in a 1st sheave half body, and the press fit female part is provided in a 2nd sheave half body.
If a portion to be press-fitted into the first sheave half is provided, the cam surface is provided radially outward from the press-fitting portion. Then, the outer diameter of the first sheave half increases and the movable sheave becomes large.
In this respect, in the present invention, since the press-fitting portion is provided in the first sheave half, the outer diameter of the first sheave half does not increase, and there is no fear that the movable sheave becomes large.
