Abstract: Embodiments provide a helical layer structure including: a helical core member which is formed of a flexible, lengthy, flat plate-like core member and which is formed of a steel plate made of a metal material, such as iron; and a polymeric coating layer which is formed of a polymeric material such as a thermosetting elastic material or a thermoplastic elastic material, and which coats the helical core member. The manufacturing method of the helical layer structure includes: a feeding step of feeding a core member having flexibility; a supply step of supplying the polymeric material having fluidity; a coating step of coating the core member with the polymeric material; a cooling step of cooling a coated intermediate which is coated with the polymeric material; and a helix formation step of helically twisting the coated intermediate to form the helical layer structure.

Abstract: A front movable louver is configured for one central horizontal fin axially supported to be turnable in the horizontal direction substantially at the up-down center inside an air outlet, while an upper auxiliary horizontal fin is axially supported so as to be storable and turnable in the horizontal direction in a storing recess provided on an upper wall surface inside the air outlet, and a lower auxiliary horizontal fin axially supported to be storable and turnable in the horizontal direction in a storing recess provided on a lower wall surface inside the air outlet. The central horizontal fin is axially supported to be turnable by pivots provided to project substantially at the centers of both sides. The upper auxiliary horizontal fin and the lower auxiliary horizontal fin are axially supported to be turnable in a manner of sticking out downstream-side end portions to a passage side.

Abstract: The front movable louver (3) includes one central fin (7) and an upper auxiliary fin (8) and a lower auxiliary fin (9) storable in storing recesses (6a, 6b) inside an air outlet. The central fin (7) is axially supported turnably by pivots (7a) provided on both sides of the vicinity of the downstream side end portion. The upper auxiliary fin (8) and the lower auxiliary fin (9) are axially supported turnably so as to stick out their downstream side end portions to the passage (5) side by pivots provided on both sides of the vicinities of the upstream side end portions. A cam link mechanism (10) turns the upper auxiliary fin (8) and the lower auxiliary fin (9) so that the upper auxiliary fin (8) sticks out its downstream side end portion to the passage side, and the lower auxiliary fin (9) becomes parallel to and approaches the central fin (7) so that these fins function as one large fin when the central fin (7) is turned in the short-side direction of the air outlet (15).
