  "textContent": "In a dog clutch-type speed change device (50) of a dog clutch-type automatic transmission including a clutch (44) that controls transmission of a torque from a motive power source (45) to a main shaft, a transmission (48) that switches gears, a motive power source-torque adjustment device (80) that adjusts the torque of the motive power source (45) when a speed change is performed, and a control device (90) that controls the motive power source-torque adjustment device (80), when changing a speed, the control device (90) reduces the torque of the motive power source (45) while the clutch (44) is in a fully connected state or a partially connected state and dogs are in an engaged state, increases the torque of the motive power source (45) that has decreased from disengagement until engagement and while the clutch (44) has been in the fully connected state or the partially connected state, and reduces the torque of the motive power source (45) again while the clutch (44) is in the fully connected state or the partially connected state so as to eliminate partial engagement of the dogs when they are engaging during a period in which the motive power source (45) is outputting an increased torque.",
