<P>PROBLEM TO BE SOLVED: To provide a motor whose vibration in a radial direction is reduced and whose constitution can be made small. <P>SOLUTION: A rear cover wall 3a of a cylindrical housing 3 includes: a flat section 31; a vibration absorption section 32, a vibration reception section 33 and a bearing storage section 34 from an outer peripheral edge. The bearing storage section 34 is a cylindrical section swollen and formed from an inner peripheral edge on an inner side of the vibration reception section 33 toward a rear side in an axial direction. An outer cylindrical face on the rear side is formed not to protrude to the rear side rather than the outer face on the rear side of the flat section 31. Vibration in a radial direction from a bearing 14 is transmitted to the bearing storage section 34 positioned on a rotor side from the flat section 31 and is transmitted to the vibration absorption section 32 via the vibration reception section 33. The vibration absorption section 32 absorbs the vibration by bending with a base end of the flat section 31 side as a fulcrum and a tip of the bearing reception section 33 side as an action point. <P>COPYRIGHT: (C)2013,JPO&INPIT |
