られている。 2. Description of the Related Art Conventionally, there are multi-stage transmission devices used in vehicles, etc., which have the following configurations, for example. In other words, by arranging a plurality of gears with different numbers of teeth in parallel on two parallel shafts, and shifting some of the gears spline-fitted to the shafts to the left and right, this can be achieved. Both gears are engaged and disengaged through a dog device provided between the gear to be shifted and another adjacent gear, thereby transmitting power between the two shafts through the opposing gears on both shafts. It is being blocked. For example, a one-way device (for example, a one-way device (for example, one-way device) that transmits only power from the input shaft side to the top gear, separate from the dog gear described above, and idles the top gear so that no power is transmitted from the output shaft side, so that the engine brake does not work. A directional clutch) is provided.

る。 Reference numeral 20 denotes a ratchet, which is formed into a polygonal shape with surfaces 21 and 22 and other surfaces as shown in FIGS. 2 and 3, and has a groove 23 on the side and a shaft 24 protruding from the side. be. As shown in FIGS. 4 and 5, the gear 6 is provided with an annular groove 27 for inserting the dog, and a notch 29 for fitting the ratchet 20 into the notch 29. When a hole 26 into which the shaft 24 is inserted is provided, and the ratchet 20 is further inserted into the hole 26 and the notch 29, the end surface of the surface 21 of the ratchet 20 closer to the surface 22 comes into contact with the end surface closer to the center of the groove 27, as shown in the figure. It is designed to hold the position like this. Further, a groove 28 is provided around the gear 6 so as to be continuous with the groove 23 of the ratchet 20 fitted therein, and an annular spring 30 is fitted into these grooves, so that one bent end of the spring 30 is connected to the gear 6. The ratchet 20 is inserted and fixed into a hole 31 provided in the shaft, and the ratchet 20 is constantly pressed toward the center of the shaft. On the side surface of the gear 5 near the gear 6, a plurality of protruding dogs 41 are arranged at predetermined intervals as shown in FIGS. 6 and 7. One end surface 42 of the dog 41 is connected to the surface 2 of the ratchet 20.
1, and the other end surface 4 is inclined so that the relationship shown in FIG.
3 is similarly inclined so that almost the entire surface thereof can come into contact with the surface 22 of the ratchet 20.

伝達される。 The present invention is constructed as described above, and when the gear 5 is now shifted in the direction of arrow D in FIG. 1, the dog 41 fits into the groove 27 of the gear 6. Therefore, due to the power transmitted from the main shaft 1 side, rotational force acts in the direction of arrow A in FIG.
Press it toward the center axis. Therefore, Ratchet 20
hits the end face near the center of the groove 27 and does not rotate, so the gear 6 is connected to the gear 5, and rotational force is transmitted.

われない。 On the other hand, when the gears 5 and 6 are in the engaged state as described above, when a rotational force is applied from the direction of arrow B, the end surface 42 of the dog 41 on the gear 5 comes into contact with the surface 21 of the ratchet 20. and push this up,
Therefore, the ratchet 20 rotates about the shaft 24, and the dog 41 therefore passes under the ratchet 20. Therefore, gear 6 and gear 5 do not engage with each other and idle, and no rotational force is transmitted between them.
