A plurality of cam floors displaced in the axial direction via a surface, and a position determining means connected to the high-speed cam floor to determine the position of the roller at the high-speed stage. When the roller provided on the operating body for moving and operating the shifter shaft contacts the multi-stage cam surface of the fixed cam body, the shifter shaft moves to the axial position corresponding to the height of the multi-stage cam surface. . Accordingly, the projection moves, the ball clutch engages, and power is transmitted from the transmission gear to the transmission shaft. Therefore, the shifter shaft is moved by sliding contact between the roller and the multi-stage cam surface, so that the resistance applied when moving the shifter shaft can be reduced, and the shift operability can be improved accordingly. 1 and 2, 1 is an engine, 2 is an engine stand, 3 is a transmission case, 4 is a transmission case for transmitting the power of the engine 1 to the transmission case 3, and 5 is a transmission case.

7, a low-speed output gear 4 provided on the main transmission shaft 28 side.
2. A low-speed gear 38, a medium-speed gear 39, and a high-speed gear 40 which always mesh with the medium-speed output gear 43 and the high-speed output gear 44, respectively.
Is pivotably supported. In the shaft of the auxiliary transmission shaft 41,
A shifter shaft 45 is inserted so as to be freely movable in the axial direction, and the shifter shaft 45 is provided with a projection 46 for selectively engaging each of the ball clutches 35, 36, 37. In addition, one end of the shifter shaft 45 is provided so as to protrude outwardly of the transmission case 3 so as to be able to move in and out, and the other end of the shifter shaft 45 is biased toward the side where the shifter shaft 45 is retracted. A compression spring 48 composed of a coil spring is interposed. Thus, by moving the shifter shaft 45 in the axial direction, the protrusion 46 is displaced, and any one of the ball clutches 35 to 37 is displaced.
, The low, medium and high speed gears 38 to 40 are selectively engaged and restrained to the sub-transmission shaft 41 to constitute a three-speed sub-transmission mechanism 47 of low speed, medium speed and high speed. As shown in FIG. 6, the projections 46 for engaging the ball clutches 35, 36, 37 are provided with depressions 46a along the curved surfaces of the respective balls. Strategies have been added to stabilize the position of the clutch and prevent the ball from coming off. In the above configuration, as shown in FIG. 7 and FIG. 8, a pair of circumferentially arranged pairs of the shifter shaft 45 are provided around the axis of the shifter shaft 45 and on the wall surface of the transmission case 3 where the shifter shaft 45 is projected. Multi-stage cam surfaces A, B, C, D, E, F, G,
A fixed cam body (hereinafter, referred to as a fixed cam) 49 having A, B, C, D, E, F, and G is fixed via detent pins 51, 51. Further, a pair of rollers 50a, 50 abutting on the multi-stage cam surfaces A, B, C,.

e, the operation body 50 for shifter shaft moving operation
And a nut 53. The fixed cam 49 is made of iron or zinc, and the rollers 50a and 50b are made of SS4.
It is made of alloy steel such as 00. An operation wire 55 extending from the sub-transmission lever 11 is connected to the sub-transmission arm 50d. By operating the sub-transmission lever 11, the sub-transmission arm 50d is swung, and each of the rollers 50
are rotated along the multi-stage cam surfaces A, B, C,... so that the shifter shaft 45 moves in the axial direction against the compression spring 48. As shown in FIG. 9, the fixed cam 49 has a low-speed cam floor A, a medium-speed cam floor C, and a high-speed cam floor E, each of which has a flat surface, as is apparent from the development of the inner surface 49a and the outer surface 49b. And tapered surfaces B and D formed of inclined surfaces connecting these cam floors. Further, a step is provided between the high-speed cam floor E and the outer end surface G of the fixed cam 49, and a tapered surface F composed of an inclined surface is formed between the high-speed cam floor E and the outer end surface G. I have. A tapered surface B between the low-speed cam floor A and the medium-speed cam floor C and a tapered surface D between the medium-speed cam floor C and the high-speed cam floor E function as guide surfaces for sliding the rollers 50a and 50b when shifting gears. And each roller 50a, 5a at the low or medium speed position.
0b functions as a positioning means. High-speed cam floor E
The tapered surface F provided at the subsequent stage is provided for each roller 5 at the high speed position.
It functions as position determining means for 0a and 50b. By operating the sub-transmission lever 11 with the above configuration, the shifter shaft 45 moves to the axial position corresponding to the position of the low speed cam floor A, the medium speed cam floor C or the high speed cam floor E, and One of the clutches 35, 36, 37 is engaged to transmit power from the transmission gears 38, 39, 40 to the auxiliary transmission shaft 41. The shifter shaft 45 is moved by the sliding contact between the rollers 50a, 50b and the multi-stage cam surfaces A, B, C,... To reduce the resistance applied when the shifter shaft 45 is moved. The speed change operability can be improved accordingly. Further, rollers 50a and 50b are arranged in a direction orthogonal to the axis of the shifter shaft 45, and the rollers 50a and 50b
Since the speed is changed by the rotation of 0b, the advantage that the mechanism for the speed change operation can be compactly obtained is also obtained. Further, in the above-mentioned structure, since the tapered surface F is provided also at the subsequent stage of the high-speed cam floor E of the fixed cam 49, positioning in a high-speed region can be easily performed. Can be done. As described above, according to the present invention, while having the advantage of being able to shift without a clutch using a ball clutch,
