<p><P>PROBLEM TO BE SOLVED: To prevent dust caused by a clutch or a brake from depositing on a rotor and a stator. <P>SOLUTION: In an inner rotor-type motor where the rotor 8 is disposed inside the stator 7, the clutch 3 is incorporated inside the rotor. A dust scattering suppressing means suppressing scattering of dust occurring in the clutch 3 to the rotor 8 and the stator 7 through a gap 32 is installed in the gap 32 between a cover 5 and a component formed of the stator 7, the rotor 8 and the clutch 3, which are arranged inside a housing 6 closed by the cover. In the dust scattering suppressing means, the gap 32 becoming a dust scattering route from a part arranged from the clutch 3 to a part in which the stator 7 is installed is bent by engaging a first circular protrusion 34 formed in an inner face 5a of the cover 5 with a first circular recess 33 formed of an end plate 16 and a holding ring 17. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
