In the above, the crankshaft 37 rotates when the engine 31 is started, and the ring gear 6 provided on the flywheel 39 is started by a starting electric motor (not shown).
This is done by driving 3. The drive gear 50 on the crankshaft 37 meshes with the driven gear 58 and receives the load of the rear wheel 20, and this resistance causes the shaft 37
It is idling above and has stopped. crankshaft 3
At a predetermined rotational speed of 7, the element 45 of the drive plate 44 expands due to centrifugal force, frictionally engages the shoe 47, and drives the clutch outer 46. That is, the centrifugal clutch shifts from the disengaged state to the connected state, and the crankshaft 37 is connected to the drive gear 50 via the clutch. As a result, the driven gear 58 is driven, and the axle 51 consisting of shafts 52, 54, 53
are driven as described above, and the left and right rear wheels 20, 20
is driven. The difference in rotation between the inner and outer rings during turning is obtained by the frictional engagement means of the flanges 60, 61 and facing 62 described above.

In this way, the centrifugal clutch 43 is disposed between the engine 31 on the crankshaft 37 and the reduction gear 50 on the drive side, and the centrifugal clutch 43 is disposed on this shaft.
The drive gear 50, which is driven when the engine is turned on, is arranged closer to the end of the crankshaft than the centrifugal clutch 43,
Since the driven gear 58 provided on the axle 51 parallel to the crankshaft 37 and the gear 50 are connected to form a power transmission system, the overhang around the end shaft of the crankshaft 37 where the small-diameter reduction gear 50 is disposed is small. Everything is housed in a case, unitized, and compact, and the structure is simple because it uses a gear mechanism. Since the clutch and ACG are arranged on both sides of the crankshaft 37, the left and right balance is good, smooth operation can be expected, and a differential device with a simple structure can be obtained as part of the brake device.

As is clear from the above, according to the present invention, the drive device used in a tricycle or the like can be made as compact and lightweight as possible, and furthermore, the structure can be simplified. In particular, since the clutch and drive gear are located on the crankshaft, the axial length is short and the space between the axle and the axle is also small, making it significantly more compact.Furthermore, since it is a gear transmission, power transmission is also improved. It's reliable and efficient. Furthermore, since the two axes are parallel and gear transmission is used, the entire width of the axle can be housed in the case, which is advantageous in terms of protecting the mechanism.
