BLOWER AND ATTACHING/DETACHING METHOD OF BLOWER

摘要

PROBLEM TO BE SOLVED: To provide a blower which can be easily attached/detached without using screw, ring or the like for fixing a fan and a rotary shaft of a motor, and an attaching/detaching method of the blower. SOLUTION: A boss part 19 and disk-like part 27 in a cross flow fan 54 are integrally formed by an elastic body. A protrusion 21 engaged with a groove 20 of a rotary shaft 32 in a motor 31 is provided to the inner peripheral surface of the boss part 19. A tip surface of the rotary shaft 32 and the motor 31 in the boss part 19 can be fixed without using a screw, a ring or the like by providing a long hole 24 to the motor side through the space of the end surface opposed to the motor 31 in the boss part 19. When removing the cross flow fan 54, the fan can be attached/detached by inserting into the long hole 24 a tool such as a flathead screwdriver and rotating the fan. COPYRIGHT: (C)2004,JPO&NCIPI
