In a specific state in which a first forward speed is formed by oil discharged from the second hydraulic pump (32) being supplied to a hydraulic drive portion (70), when a failure occurs in which a discharge pressure of the second hydraulic pump (32) is decreased, a state of the hydraulic circuit (8) is switched from a first state in which oil discharged from the second hydraulic pump (32) is supplied to the hydraulic drive portion (70) to a second state in which oil discharged from the first hydraulic pump (31) is supplied to the hydraulic drive portion (70).",
