ABSTRACT:
An air-conditioning blow-out port device includes a housing of synthetic resin; a plurality of blades of synthetic resin each having a blade body disposed within the housing pairs of shaft bores provided in a coaxial arrangement in each pair in opposed portions of a peripheral wall of the housing; a pair of support shafts projectingly provided on opposite ends of the blade body and rotatably fitted in the shaft bores. A pivotal mounting portion is provided on each of the blades, and an interlocking link interlockingly connects the pivotal mounting portions of the blades. The pivotal mounting portion is comprised of a pivotal supporting shaft which is projectingly provided in parallel to the support shaft at an end of each blade body to extend through a pivotal supporting bore in the interlocking link, and a slip-off preventing projection provided at a tip end of the pivotal supporting shaft to engage an edge of the pivotal supporting bore. Thus, the pivotal mounting portion can be provided within an extent of thickness of the blade to provide a reduced spacing between the blades.
