Document Type and Number:
WIPO Patent Application WO/2021/100689
Kind Code:
A1
Abstract:
[Problem] To enable two air volume adjustment doors that are driven by a single drive source to be simultaneously adjusted at both a full-open position and a full-closed position. [Solution] A vehicle duct device (30) comprises a first air volume adjustment door (70) that is driven by a drive source (100) to open/close a first blowing path (41), a second air volume adjustment door (80) that opens/closes a second blowing path (51), an urging mechanism (110) provided between the two doors (70, 80), an expansion restriction unit (120) that restricts the expansion of the second air volume adjustment door (80) with respect to the first air volume adjustment door (70) in a first rotation direction (R1) to a predetermined angle (θ), and a full-open definition unit (132) that defines the full-open position of the second circumferential wall (81). The urging mechanism (110) can perform the urging in the direction in which the second air volume adjustment door (80) would rotate in the first rotation direction (R1) with respect to the first air volume adjustment door (70).
