BLOWER IN AIR-CONDITIONING SYSTEM

PURPOSE:To facilitate and automatize the coupling process of the shaft of a motor with a boss section including, on its inner surface, a shape memory alloy liner having one end thereof exposed to the outside, by forming the end plate section of peripheral edge of the boss section from a rubber plate so that the coupling between the boss section and the motor shaft may be made only by heating. CONSTITUTION:A boss section 16 including on its inner surface a shape memory alloy liner 20 having one end exposed to the outside is arranged in the center section of an end plate section 15 which is attached to the other end of a fan 13. Further, a rubber plate 17 is provided on the peripheral edge of the boss section 16 so that the rubber plate 17 supports the boss section. A guide taper 18 is formed in an inserted section opening in the peripheral edge of the boss section 16. A shaft 19 is a shaft of a fan motor which is not shown and which is beforehand attached to a compartment unit body. With this arrangement, after the boss section 16 is inserted obliquely onto the motor shaft 19 while the rubber plate 17 of the end plate section 15 is flexibly deformed, the shaft 19 and the boss section 16 may be coupled together only by heating. Thereby it is possible to facilitate and automatize the coupling thereof.
