<p>PROBLEM TO BE SOLVED: To provide a ceiling embedded air conditioner equipped with pivotal shafts, provided at both sides of an airflow direction changing plate, and an oil damper device, provided on a connecting unit between a connecting body, connected to the pivotal shafts through connecting members or the connecting member to retain the airflow direction changing plate at a pivotal angle, arbitrarily changed by operating the airflow direction changing plate manually. SOLUTION: A ceiling embedded air conditioner is provided with an oil damper device, constituted of a pivotal shaft 6, whose tip end part 6a is opened and whose bottom surface is formed so as to have a bottomed cylindrical shape having a supporting shaft unit 6b on the bottom surface of the same, a connecting body 7, constituted of a supporting shaft 7a whose base end unit is supported by the supporting shaft unit and a substantially disc type resistant body 7c provided on the outer periphery of the same supporting shaft so as to be inserted through an opening on the tip end unit while whose tip end unit 7b is connected to the connecting member, oil (a) for frictional resistance, which is sealed between the pivotal shaft and the supporting shaft as well as a resistance body, and a retaining unit for retaining the pivotal shaft and the connecting body mutually.</p> |
