いた。b Prior art and problems solved by the present invention In front-wheel drive or front-wheel drive vehicles, when transmitting power from the output shaft to which the power of the crankshaft is transmitted to the front drive shaft, conventionally the crankshaft is disposed between the two shafts. Because of this, I had to suspend the chain around the crankshaft. In addition, there is a considerable distance between the output shaft and the front wheel drive shaft, which causes problems such as loosening of the chain, and it has been desired to solve this problem practically without increasing the number of parts.

ン７に噛合している。 In Figures 1 and 2, 1 is the engine body, 2 is a crankshaft located between an output shaft and a front wheel drive shaft, which will be described later, 3 is an output shaft that takes out the output of the crankshaft 2, and 4 is a front wheel drive shaft. This is a front wheel drive shaft that drives wheels (not shown). The rotation of the crankshaft 2 is transmitted to the output shaft 3 via a transmission (not shown), and the rotation of the crankshaft 2 is transmitted from sprockets 5 and 6 attached to the output shaft 3 to the front wheel drive shaft via chains 7 and 8. The power is transmitted to the sprocket 9 of No. 4 and the sprocket of the rear wheel drive shaft (not shown). The crankshaft 2 is rotatably provided with a chain guide sprocket 12 between the magnet 10 and the recoil starter 11, and the chain guide sprocket 12 transfers the power from the output shaft 3 to the sprocket 9 of the front wheel drive shaft 4. It meshes with the chain 7 that transmits the signal.

ための特別の車軸を別途に設ける必要がない。Effect According to the above-mentioned front wheel drive power transmission device, the rotation of the crankshaft 2 transmitted to the output shaft 3 is transmitted from the sprocket 5 to the sprocket 9 of the front wheel drive shaft 4 via the chain 7. In this way, the front wheels supported by the front wheel drive shaft 4 are driven. At this time, the chain 7 is meshed with and guided by the chain guide sprocket 12 supported by the crankshaft 2, so that the chain 7 is prevented from shaking, loosening, etc. Note that with this configuration, there is no need to separately provide a special axle for providing the chain guide sprocket 12.

その効果は大きい。f Effects As described above, according to the front wheel drive power transmission device of the present invention, the chain can be guided by the chain guide sprocket of the crankshaft, thereby preventing the chain from shaking or loosening. power transmission can be performed reliably. In addition, since the crankshaft is used as the rotation axis of the chain guide sprocket, there is no need to provide a separate rotation axis, so there is no need for an increase in the number of parts.
The effect is great.
