Abstract: A structure for connecting an air-conditioning duct to an air-conditioning unit; the air-conditioning unit 1 having a first air supply outlet 11 and a second air supply outlet 12 adjacent with each other, the air-conditioning duct having a first air passage and a second air passage adjacent with each other, wherein the first air supply outlet 11 and the second air supply outlet 12 include a U-shaped auxiliary wall 2 having a notched part K at one side therearound, a supply outlet boundary wall 130 separating the first air supply outlet 11 and the second air supply outlet 12, and a duct side step part Z is formed between an opening rim of a first duct 31 and an opening rim of a second duct 32, the duct side step part Z is contacted with is contacted with the supply outlet boundary wall 130 to install the air-conditioning duct 2 to the air-conditioning unit 1.

Abstract: Provided is a tubular molded foam with a plate portion capable of reliably preventing the occurrence of an unwanted lump on the inside of a tube body even when the molding is manufactured using a molten resin having a high expansion ratio. The tubular molded foam includes a tube body and a plate portion joined with an outside of the tube body. The plate portion has a recess in the vicinity of a joint surface with the tube body.

Abstract: The invention provides a method for manufacturing a climate control duct, the method capable of improving a characteristic of transferring a shape of a protrusion onto a surface of a duct and capable of preventing reduction in ventilation efficiency. In order to manufacture a climate control duct having a protrusion formed on an outer peripheral surface thereof, the method includes subjecting an extruded foamed resin to blow molding by use of a duct-shaped mold in which a groove for transfer of a shape of the protrusion is formed on at least part of a surface thereof. Herein, the following relations are satisfied: 0.5 mm<D<5 mm, D<W<4×D, and W<2×T, in which W represents a width of the groove, D represents a depth of the groove, and T represents a thickness of the foamed resin.

Abstract: An air-conditioning duct for vehicles with one duct mutually connected and fixed to other duct, wherein one duct is formed by incorporating a first unit duct with a flange formed around an opening periphery thereof and a second unit duct with a flange formed around an opening periphery thereof in parallel, other duct is formed by incorporating a third unit duct with a flange formed around an opening periphery thereof and a fourth unit duct with a flange formed around an opening periphery thereof in parallel, the flange formed on the a boundary side of the first unit duct and the flange formed on the boundary side of the second unit duct are fixed with one over another, and the flange formed on the boundary side of the third unit duct and the flange formed on the boundary side of the fourth unit duct are fixed with one over another.
