Title:
AIR-CONDITIONING DUCT
Document Type and Number:
Japanese Patent JP2015003414
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air-conditioning duct in which narrow weld ribs can be reliably formed during blow-molding and the interval between adjoining two weld ribs can be set narrower, thereby improving the design of a car interior component.SOLUTION: An air-conditioning duct 10 has a duct body unit that is formed by expanding a parison and compression-molded sections 30 that are formed by partially collapsing the parison. The compression-molded section 30 has: a base part 31 that faces the back surface 22a of an instrument panel 22; recessed parts 33 that are recessed toward the front surface 31b side from the back surface 31a side of the base part 31 and extend in a vibrating direction; and weld ribs 37 that are provided on the front surface 31b side of the base part 31 in multiple units per one recessed part 33, protrude toward the back surface 22a side of the instrument panel 22 while extending in the vibrating direction, and are vibration-welded to the back surface 22a of the instrument panel 22.
