PURPOSE: A fan shaft jointing apparatus of an air conditioner is provided to reduce noise of an indoor unit by eliminating a ball bearing in the supporting structure of a connecting shaft, and to improve working efficiency and cut down expenses by reducing parts with supporting the connecting shaft by the single supporter. CONSTITUTION: A fan shaft connecting device of an air conditioner is composed of a connecting shaft(51) fixed in a cross flow fan(50A); an assembling bolt(53) fixing the connecting shaft to a cross flow fan(50B); and a shaft supporting unit(55) installed between cross flow fans to support the connecting shaft. The connecting shaft is made of metal, and the surface of the connecting shaft is ground. A through hole is formed in the supporting unit to insert the connecting shaft, and the shaft supporting unit is fixed in the case. Plural cross flow fans are arranged to move airflow forcibly for sucking and discharging air. The noise of the indoor unit is reduced with eliminating the ball bearing from the supporting structure of the connecting shaft. Working efficiency is improved, and expenses are reduced with reducing parts by supporting the connecting shaft with the single shaft supporting unit. |
