分を除いた平坦部を介して、ハブ２に伝達される。The hub 2 has a two-piece structure divided into two parts in the axial direction, and accommodates a drive wheel 5 having a small diameter therein.
The inner peripheral surface of the hub 2 forms an endless track 4 continuous in the circumferential direction. The plurality of pulleys 3 with bearings are inscribed in the upper part of the endless track 4, and the drive wheels 5 are inscribed in the lower part thereof. Both sides of the endless track 4 are reduced in diameter toward the outside. Internal gears 6 and 6 are formed on the reduced diameter portions on both sides. Correspondingly, the outer surfaces of both side portions of the drive wheel 5 are reduced in diameter toward the outside, and the external gears 7, 7 formed on the reduced diameter portions on both sides mesh with the internal gears 6, 6. Therefore, the drive wheel 5 is inscribed in the endless track 4 without slipping. The load received by the drive wheel 5 is transmitted to the hub 2 via the flat portion excluding the gear portion.

の汚れを防ぐ防塵カバーである。The drive wheel 5 is fixed to a rotatable support shaft 8 attached to the vehicle body. The support shaft 8 is connected to a pedal gear 11 via a gear 9 and a chain 10. Therefore, when the pedal 12 is pedaled, its rotation is transmitted to the support shaft 8 and further transmitted to the hub 2 via the drive wheel 5. Further, since the support shaft 8 receives a rear load of the bicycle, the load is transmitted to the hub 2 via the drive wheel 5.
Reference numeral 18 is a brake attached to the support shaft 8, and 19 is a dustproof cover for preventing the inside of the hub 2 from being soiled.

It is rotatably supported with respect to the hub 2 by a plurality of pulleys 3 with bearings attached to the hub 2. The plurality of pulleys 3 with bearings are inscribed in the upper part of the endless track 4 and
We are trying to stabilize. Here, the rotation lever 14 is supported so as to be rotatable around the support shaft 8,
An operation lever 15 rotatably attached to a support shaft of the pedal gear 11 is connected by a pair of upper and lower connecting rods 16, 16. The operating lever 15 is the brake lever 1
By gripping 7, it can freely rotate back and forth, rotate backward in four steps, and rotate forward in two steps. Then, the rotating lever 14, the operating lever 15, and the connecting rods 16, 16
Constitutes a parallel link mechanism and also constitutes a hub operating means in the present embodiment.

７を離すと、操作レバー１５が回動位置に固定される。That is, when the operation lever 15 is rotated rearward from the neutral position, the rotation lever 14 is also rotated rearward, and the drive wheel 5 for the hub 2 is moved along with the displacement of the hub 2.
The inner contact of the above moves from immediately above the grounding point of the rear wheel 1 to the front along the endless track 4 of the hub 2. On the contrary, when the operation lever 15 is rotated forward from the neutral position, the rotation lever 14 is also rotated forward, and the displacement of the hub 2 is caused by the rotation lever 14.
The inner contact point of the drive wheel 5 with respect to the hub 2 moves rearward from directly above the grounding point of the rear wheel 1 along the endless track 4 of the hub 2. After rotating the operation lever 15, the brake lever 1
When 7 is released, the operation lever 15 is fixed at the rotating position.

Rotate one step. With this displacement of the hub 2, the inner contact of the drive wheel 5 with respect to the hub 2 moves forward from directly above the grounding point of the rear wheel 1 along the endless track 4 of the hub 2. Here, the drive wheel 5 receives the rear load of the bicycle. Therefore, the load point moves to the front of the ground contact point of the rear wheel 1, accompanied thereto
Then, the center of gravity moves forward.

る。When traveling downhill, the operating lever 15
Rotate forward. As a result, the rotation lever 14
It rotates forward around the rotary shaft 8. With this displacement of the hub 2, the inner contact of the drive wheel 5 with respect to the hub 2 becomes
From just above the grounding point of the rear wheel 1, it moves rearward along the endless track 4 of the hub 2. As a result, the load point moves to the rear of the grounding point of the rear wheel 1, and the center of gravity moves to the rear with this. That is, the bicycle can be decelerated without using the handbrake, and a function similar to the engine brake of an automobile can be obtained. Therefore, it is possible to drive safely on a steep downhill.
【００１７】操作レバー１５を前方へ２段回動させたと
