が大きく変動し勝ちとなる不都合を伴う。 The applicant of this application has previously developed a device of this type in which a pair of left and right axles having a pair of left and right rear wheels are attached to the rear of a transmission case extending rearward from the engine via a differential clutch in an oil chamber formed within the case. We have proposed a type in which they are connected to each other and installed in parallel, and one of them is connected to the output shaft of the engine via a transmission mechanism inside the case, but in this case, depending on the left and right slope of the road surface, While the differential clutch moves up and down in response, the oil level in the oil chamber is kept approximately horizontal, and thus the clutch is disadvantaged in that the depth of immersion in the oil tends to fluctuate greatly.

を有する。 In this way, according to the present invention, the transmission case 2
The transmission mechanism 3 inside is connected to the engine output shaft 4 and is connected to the center line
A belt mechanism 3a disposed on one side of the belt mechanism 3a is connected to the mechanism 3a via a centrifugal clutch 10 provided on a drive shaft 5 on the driven side of the belt mechanism 3a. and a reduction gear mechanism 3b disposed near the center line XX, and the differential clutch 9 is arranged in parallel to the gear 3c at the output end of the gear mechanism 3b, and the differential clutch 9 is connected to the left and right rear wheels. Since the differential clutch is located near the center line XX between 6 and 6, even when the vehicle body is tilted from side to side, the differential clutch does not deviate greatly up and down, and is always kept in a substantially constant relationship with the oil level in the oil chamber 8. The axles 7, 7 coaxial with the differential clutch 9 can improve the sag operation.
This is arranged close to the drive shaft 5 so that the outer circumference of the differential clutch 9 and the outer circumference of the centrifugal clutch 10 on the drive shaft 5 overlap in the axial direction, so that the distance between the drive shaft 5 and the axles 7, 7 is This has the advantage that the gear train can be organized compactly by reducing the number of gears.
