Two air volume adjusting doors driven by a single drive source can be simultaneously adjusted in both a fully opened position and a fully closed position. A vehicle-use duct device (30) includes a first air volume adjusting door (70) that is driven by a drive source (100) and opens and closes a first air feed passage (41), a second air volume adjusting door (80) that opens and closes a second air feed passage (51), a biasing mechanism (110) provided between the doors (70, 80), an angle restricting portion (120) that restricts a pivoting of the second air volume adjusting door (80) with respect to the first air volume adjusting door (70) to a constant angle (θ) in a first pivoting direction (R1), and a full opening regulating portion (132) that regulates a fully opened position of the second peripheral wall (81). The biasing mechanism (110) can bias in a direction such that the second air volume adjusting door (80) attempts to pivot in the first pivoting direction (R1) with respect to the first air volume adjusting door (70).
