<P>PROBLEM TO BE SOLVED: To provide a motor which does not require an adhesive to fix a magnet to a holder and prevents displacement of the magnet relative to the holder over a long period. <P>SOLUTION: A connection cylinder part 51 of a holder 50 is formed in a cylindrical shape and is coaxially provided with a shaft 40 so as to connect with one end of the shaft 40. An annular plate 52 is formed so as to annularly extend from one end of the connection cylinder part 51 in a radially outward direction. A housing cylinder part 53 is cylindrically formed so as to extend from an outer peripheral edge of the annular plate 52. A magnet 60 has a bottom surface 61 facing the shaft 40 side, a top surface 62 facing the side opposite to the shaft 40, and a side surface 63 connecting the bottom surface 61 and the top surface 62. The housing cylinder part 53 has a dropping restriction part 531 which restricts the magnet 60 from dropping from the housing cylinder part 53 by locking the magnet 60. <P>COPYRIGHT: (C)2012,JPO&INPIT |
