<P>PROBLEM TO BE SOLVED: To improve the accuracy of a gap by reducing the size, the number of components and the electromagnetic vibration of a blower and to facilitate the replacement or additional establishment of the fan or the rotor of the blower. <P>SOLUTION: The blower includes a rotating shaft 2b axially protruding from the center of the end plate 2a of the fan 2 at a motor 5 side. The motor 5 has a shaft 7 formed in a cylindrical state with a bottom at the center of the bottom, a stator 6 having a stator core 6b, on which a coil 6a of the side of the shaft 7 is wound, and which is formed integrally with the stator core 6b, and a rotor 9 fixed to the outer periphery of the shaft 7 rotatably via a bearing 8 and having a protrusion 9a protruding from one side toward the end plate 2a of the fan 2. The blower further includes a coupling means 3 made of an elastic material interposed between the rotating shaft 2a and the protrusion 9a. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
