    摘要： An electric device suitable for a bicycle is disclosed. Said electric pedal device includes a housing (10) configured to form a space therein, a rotating shaft (20) passes through both ends of the housing, a reduction gear set (30) configured to reduce a rotational force of the rotating shaft, a rotor (40) configured to rotate by an output of the reduction gear set, a stator (50) including a winding around core laminations (120) and a hub (100). Wherein said core laminations are coupled to the hub while prevented by a structure that an axial deviation relative to the hub is possible. Further a print circuit board (60), controlling the electric power to the stator, is fixed to said housing.

    摘要： In the disclosure, a rotor having a high productivity rate for a magnet reinforcement tube and for which it is easy to ensure strength is obtained.
    This rotor includes a rotor shaft, a permanent magnet held at an outer periphery of the rotor shaft, and a magnet reinforcement tube (24) formed in a cylindrical shape and covering the permanent magnet from an outer peripheral side of the permanent magnet. The magnet reinforcement tube (24) includes plural layers (24A, 24B, 24C, and 24D) layered in a radial direction, and has plural fiber sheets (26) wound individually for each layer (24A, 24B, 24C, and 24D), and each fiber sheet (26) being solidified with resin.
