PROBLEM TO BE SOLVED: To reduce parts, to facilitate assembling and to attain cost-down by connecting a front lid case to a fixing plate and directly fixing a pattern reel to a cup-shaped rotary body being an outer rotor so as to attain integration. SOLUTION: The front lid case 5 integratedly provided with a cylinder part 5a is fixed to the fixing plate 11 by a fitting screw 10a. A rotary shaft 1 is freely rotatably disposed at the inner side of the cylinder part 5a with a pair of bearings 6 and also a ring-shaped stater 3 provided with a coil 3a with an insulating body 23, which is connected to a lead line 7, is fixed at the outer side of the cylinder part 5a. A magnet 21 is fitted in the inner periphery of a cup-shaped rotary body 2 which is attached to the end part of the rotary shaft 1 with a bush 20 and the magnet 21 is constituted so as to be rotated in accordance with the outer peripheral position to the stater 3. The pattern reel 9 formed as a cup-shape as a whole is coaxially arranged in the outer end of the cup-shaped rotary body 2 with the cup-shaped rotary body 2. |
