Both the rotating element and the twelfth rotating element may be ring gears.
- the first planetary gear mechanism may be configured on the outer peripheral side of the third planetary gear mechanism. If it carries out like this, although it becomes large about a radial direction, it can be shortened about an axial direction. That is, it can be made the same as the axial length of the automatic transmission device by three planetary gear mechanisms.
- the second planetary gear mechanism, the first planetary gear mechanism, the third planetary gear mechanism, and the fourth planetary gear mechanism are arranged in this order. It can also be.
- the third brake may be configured as a dog brake.
- the dog brake is susceptible to shock when engaged, and synchronous control is required to synchronize the rotation.
- the third brake is engaged continuously from the first forward speed to the fourth forward speed and moves forward from the fifth forward speed. Since the release continues up to the ninth gear, engagement and release are not repeated frequently, and the frequency of occurrence of synchronous control is low. For this reason, even if the dog brake is employed, the deterioration of the shift feeling is suppressed.

- 22, 32, 42, ring gears 13, 23, 33, 43) is approximately 4.4 times the rotational speed of the input shaft 3, but the conventional automatic transmission device 901 has a maximum rotational speed. Is approximately 5.5 times the rotational speed of the input shaft 903.

- the maximum value of the relative rotational speed is 5.5 times the rotational speed of the input shaft 903. Therefore, in the automatic transmission device 1 according to the embodiment, the maximum value of the relative rotational speeds of the engagement elements can be reduced as compared with the automatic transmission device 901 according to the conventional example.
- a wet multi-plate clutch or a wet multi-plate brake that is normally used as an engagement element can be used, compared with the conventional automatic transmission device 901 that uses a dog clutch or a dog brake.

- the sun gear 41 of the fourth planetary gear mechanism 40 is connected to the case 2 via the brake B3
- the third coupling element 53 ring gear 13, carrier 42
- the ninth forward speed as the highest speed is formed by engaging the clutch C1, the clutch C3, and the brake B1, and releasing the clutch C2, the brake B2, and the brake B3.
- the planetary gear mechanism that operates as a gear for torque transmission between the input shaft 3 and the output gear 4 is the first planetary gear mechanism 10 and the third planetary gear mechanism 30, and the forward 9-speed of the highest speed stage.

- the number of planetary gear mechanisms that operate for torque transmission at the highest speed stage can be reduced, loss due to gear meshing can be reduced, and torque transmission efficiency can be increased.
- the clutch C1, the brake B1, and the brake B2 are engaged and the clutch C2, the clutch C3, and the brake B3 are disengaged at the eighth forward speed that is one step before the highest speed stage.
- the planetary gear mechanism that operates as a gear for torque transmission between the input shaft 3 and the output gear 4 is only one of the first planetary gear mechanisms 10, and the advancing one before the highest speed stage.
- the first planetary gear mechanism 10 is arranged on the outer peripheral side of the third planetary gear mechanism 30, compared to a configuration in which four planetary gear mechanisms are arranged side by side. Although it becomes larger in the radial direction, it can be shortened in the axial direction. That is, it can be made the same as the axial length of the automatic transmission device in which the three planetary gear mechanisms are arranged side by side.
- the maximum number of rotations in each of the three rotating elements constituting the first to fourth planetary gear mechanisms 10, 20, 30, and 40 is higher than that of the automatic transmission device 901 of the conventional example.

- the operation table and speed diagram of the automatic transmission device 1B according to the modification are the same as those in FIGS.
- the dog brake is susceptible to shock when engaged, and synchronous control is required to synchronize the rotation.
- the brake B3 is continuously engaged from the first forward speed to the fourth forward speed, and from the fifth forward speed to the forward 9 speed. Since the release is continued up to the speed stage, the engagement and release are not repeated frequently, and the frequency of occurrence of the synchronous control is low. For this reason, even if the dog brake is employed, the deterioration of the shift feeling is suppressed.
- the gear ratios ⁇ 1, ⁇ 2, ⁇ 3, ⁇ 4 of the first to fourth planetary gear mechanisms 10, 20, 30, 40 are 0.60, 0.65, 0.45, 0. .35 is used, but the gear ratios ⁇ 1, ⁇ 2, ⁇ 3, and ⁇ 4 are not limited to these values.
