Since the present invention is configured as described above, when the kick shaft 30 is rotated at the time of starting, the kick driven gear 34 and the sub gear 36 are rotated via the gears 32 and 33. Due to this resistance, the second friction spring 37 slips, causing the hard driven gear 34 and the retainer 27 integrated therewith to move forward in the direction of arrow A in FIG. , the one-way clutch 28 is disengaged to cut off power transmission to the counter shaft 20, and the transmission from the driven shaft 23 to the low-speed gear 22 and the low-speed transmission shaft 1
0, crankshaft 2 via one-way clutch 14
to drive. During this time, the parts after the one-way clutch 28 are not driven, so the tightening force is reduced.

When the one-way clutch 28 is engaged and the first gear clutch is disengaged, when the gear is rotated backwards, the one-way clutch 28 remains locked and is driven in the reverse direction from the wheel side, and attempts to rotate clockwise in FIG. 3. . Now, in the same figure, the first friction spring 2
Considering that there is no 9, one-way clutch 2
8 is rotated in the opposite direction from the cam member 24 to the driven shaft 2.
3, the friction force of the second friction spring 37 drives the sub gear 36, and the driven gear 34 is driven in the same direction from the sub gear 36 via the idle gear 33. Therefore, the rotation of the gear 34 is delayed, and as shown in FIG.
35b, the retainer 27 integrated with the hard driven gear 34 and the roller 26 held therein
rotates clockwise later than the cam member 24,
As shown in FIG. 5, the clutch 28 is released.

However, due to the clockwise rotation of the cam member 24, a friction force in the winding direction acts on the first friction spring 29, causing it to rotate integrally, and its protruding end rotates the retainer 27 in the same direction, causing the roller 2
6 is held in a state in which it is substantially in contact with the peak of the cam member 24. Therefore, when the rotation of the engine 1 is increased and the driven shaft 23 is driven in the direction of arrow A, the cam member 2
4. Even if there is a slight play in the contact area between the roller 26 and the outer 25, the play in the retainer 27 is removed by the drive system of the sub gear 36, idle gear 33, and hard driven gear 34, and the one-way clutch 28 is immediately brought into the connected state. , and almost no shock occurs.

According to the present invention, the one-way clutch 28 that connects the driven shaft 23 of the low-speed transmission system and the output shaft 18 of the high-speed transmission system is connected to a cam formed at one end of a cylindrical portion that is fitted into the driven shaft. Part 2
4, a retainer 27 that supports a roller 26 that engages with the cam member 24, and an outer 25 on the output shaft 18 side that supports the roller 26 of the retainer 27 from the outer periphery.
A friction spring 29 that restricts the movement range of the roller 26 relative to the cam member 24 is wound around a cylindrical portion integral with the cam member 24, and one end of the friction spring 29 is engaged with the retainer 27. roller 2 to the cam member from
The range of movement of the clutch 6 is regulated, and when starting after rearward handling with the engine hot, there is almost no shock caused by the one-way clutch 28 being jammed, which improves the durability of the clutch 28 and allows a smooth start. have an effect.
