Abstract
A rotor of rotary electric machines includes a rotor core which include first and second core blocks. The first core block is formed by stacking the steel plates in a state where the steel plates are engaged by a first crimping portion and skewed in a first direction in a circumferential direction. The second core block is formed by stacking the steel plates in a state where the steel plates are engaged by a second crimping portion and skewed in a second direction facing the first direction. The first and second core blocks are connected in an axial direction in the rotor core. A hole for inserting the first crimping portion is provided in an intermediate steel plate which is part of the annular steel plates. This intermediate steel plate is provided at a block boundary position of the second core bock and is connected to the first core block.
