示す通り扇形歯車（２）の位置Ａ、Ｂ。Also, the reason why a double chain is necessary is the position of the low gear (A
), the diameter of the circular gear made up of eight sector gears (2) is the smallest, so it is located on both sides of the sector gear (2). This is because the sector gears (2) overlap, albeit slightly, and on the other hand, at the 3rd gear tC+ position, the sector gears (2) located on both sides open at a short interval, making the outer diameter of the first circular gear the largest. The fan-shaped gear (2) is attached to eight central main shafts (gear stays (3) made up of one piece as shown in Figure 2).
m The slide groove (5) cut into the wheel (2) will fit into it, the gear holder (6) will fit over it, the standing bolt (7) will come off with the bearing (4), and the sector gear (2) will come off. The structure is such that the sector gear (2) can slide in and out quickly while preventing this. As shown in FIG. 1, the slides rjJ are at the positions A and B of the sector gear (2).

合、２速、３速と成る。When all eight sector gears (2) become circular gears at the W position due to the return spring (8) and the raising cam (9), the gear is in first speed. In the case of the (B) position and (C) position, the position will be 2nd speed or 3rd speed.

千エンとＪｌ：、にする。To explain step by step the explanation of item 1-1 in Figures 1, 2, and 3, at the position of the sector gear, eight gears form a circular gear, and when it is rotating, the raising cam ( 9) is the circumference Jr.
, enters the center from the position of point fAi, and the sector tooth i'p(2)
is pulled toward the center main axis (]) by the return spring (8), so the outer slide bearing (4) supports the tip of the slide groove (5) and moves fAf on one circumference.
The 8th gear in position 16 becomes a circular gear, making smooth rotation possible.

歯車（２）がフックし固定される。When the sector gear shifts to the 1st speed 11 (from the A+ position to the 2nd speed] old B) position, the first step is to pass through the car box case 03) shown in Figure 2 in order to raise the 1st gear cam (9). −
1 - Turn the cam shaft (10) to the left, and the top of the raising cam is fB.
) fixed in position. At the same time, the toe cam (11)
Since the lower cam shaft (12) rotates to the left in conjunction with the L cam shaft 00), the sector gear (2) spreads outward and the outer diameter can be changed freely. The sector gear is pushed to the speed fB+ position. When sliding to the 2nd speed + 1 fB) position, as shown in Figure 3, the rack gear (1

The fan gear (2) is hooked and fixed at the cast collar gear hook shaft (17) position.

前記増速に対しこれより減速を説明致す。In contrast to the speed increase mentioned above, I will now explain the deceleration.

する事も可能である。First, the deceleration from the 3rd gear (C) position to the 2nd gear fB) position is linked to the lowering cam (11) and the gear box case (13)
When the lowering cam shaft (12) fixed through the shell is turned to the right and the top of the lowering cam (11) is fixed at the 2nd speed fB) position, the sector gear rotates to the right and holds the fulcrum stopper gear hook shaft (17). Stopper gear hook (16
) is pushed away, the stopper footer (+6j stopper hook return spring 08) that was hanging on the stopper gear 04) is extended, and at the same time the hook is removed, the sector gear (2) is pushed back against the return spring (
8) The lowering cam (lower cam)
9) has turned to the right and is in the 2nd gear tB+ position, so the sector gear (
2) descends to point fB) and is supported by the upward cam (9),
As the stopper gear (1) works and rotates once, all eight sector gears (2) are aligned at the 2nd gear tB+ position, forming a circular gear, and are decelerated to 2nd gear. Also, from the 2nd gear tB+ position The same applies to deceleration to 1st speed tA+ position.Also, 3
It is also possible to decelerate from the C1 position to the 1st speed iA position if necessary.
最後に成りましたが、増速又は減速の場合はカムによる
扇形歯車（２）の移動は、チェノのかかっていないフリ
ーの部分の範囲で行う構造とする。Last but not least, in the case of speed increase or deceleration, the sector gear (2) is moved by the cam within the free area where the chain is not engaged.

きな差があっても。A feature of the present invention is that it is applicable to a wide range of bicycles, etc.Although the main text shows three speeds, it is also possible to change speeds to several speeds as long as the cam and other devices allow. Also, there is no chain noise, carring noise, etc. when changing gears, even if there is a somewhat large difference in the carr ratio between 1st, 2nd, and 3rd gears.

軸が約半回転すればチェノの実動有効直径が変り事実１
−増速又は減速となる。If the radius of the 6 to 11 sector gears changes one by one and the main shaft rotates about half a revolution, the actual effective diameter of the chino will change.Fact 1
- Speed up or slow down.

減速した歯車に力が働きスムーズではあるが敏速にギヤ
ーシフトが出来る。Also, when changing gears on the other hand, the sector gear (z) becomes free.
Since six or more gears -1- are moved, the sector gear (2) that has been accelerated or decelerated can be accelerated or decelerated with a slight rotation of the main shaft (1).
Power is applied to the gears that have decelerated, allowing for smooth but quick gear shifts.
ダブルチェンであるゆえ、チェノの横揺がなくチェノが
外れる等のトラブルが少なく安全性が高い。Because it is a double chain, there is no sideways movement of the chain and there are fewer problems such as the chain coming off, making it highly safe.
