TIME-PIECE MACHINE BODY

PURPOSE:To reduce the effect on the gap accuracy in the horizontal direction between a stator magnetic pole part and a rotor by supporting the end part of a rotor shaft on the side of a permanent magnet by the bearing of the middle plate positioned in the horizontal direction of a stator. CONSTITUTION:Since the bearing 2b of a lower case 2 is apt to become lower than the bearing 3b of the middle plate 4 directly performing positioning in the horizontal direction of a stator 4, the positional accuracy in the horizontal direction to the stator is taken by supporting the end part 5c of the rotor shaft on the side of a pinion positioned remotely from a permanent magnet 6 and directly performing positioning in the horizontal direction of the stator 4. The end part 5b of the rotor shaft on the side of the permanent magnet positioned in a state nearer to the magnet 6 is supported by the bearing 3b of the middle plate 3 enhanced in the positional accuracy in the horizontal direction to the stator 4.
