<P>PROBLEM TO BE SOLVED: To provide a rotary electric machine that can be easily and quickly assembled. <P>SOLUTION: The electric generator includes: a rotor 31 that includes a rotor core 32 and a rotation shaft 33; a stator 21 that includes a stator core 22 disposed to face the rotor core 32 in a radial direction; and a rotation shaft support hole 13 that rotatably supports the rotation shaft 33 of the rotor 31. The length L1 from the edge part 32b of the rotor core 32 on the side of the rotation shaft support hole 13 to the point where a second ball bearing 36 first contacts the rotation shaft support hole 13 when the second ball bearing is inserted into the rotation shaft support hole 13, in an extension direction of the rotation shaft 33 is configured to be larger than the length L2 from the edge part 13b of the rotation shaft support hole 13 on the side of the stator 21 to the edge part 22a of the stator core 22 on a side opposite to the rotation shaft support hole 13, in the extension direction of the rotation shaft 33. <P>COPYRIGHT: (C)2012,JPO&INPIT |
