According to (2), the outer diameter side end portion of the second refrigerant flow path hole is located further on the radially outer side than the outermost diameter portion of the first refrigerant flow path hole, so that the refrigerant can be easily guided to the second refrigerant flow path hole.
(3) The rotating electrical machine according to (1) or (2), in which
the first refrigerant discharge hole is provided to overlap the second refrigerant flow path hole in the circumferential direction,
a plurality of the first refrigerant discharge holes and a plurality of the second refrigerant flow path holes are provided at equal intervals in the circumferential direction,
a plurality of the second refrigerant discharge holes are provided at equal intervals in the circumferential direction,
the first refrigerant discharge holes and the second refrigerant discharge holes are alternately arranged in the circumferential direction, and
the first refrigerant flow path holes are disposed between the first refrigerant discharge holes and the second refrigerant discharge holes in the circumferential direction.
According to (3), the first refrigerant discharge holes and the second refrigerant discharge holes are alternately arranged in the circumferential direction when viewed from the axial direction and the first refrigerant flow path holes are arranged between the first refrigerant discharge holes and the second refrigerant discharge holes. Therefore, the refrigerant flowing through the first refrigerant flow path holes can be distributed substantially evenly into the second refrigerant flow path holes (first refrigerant discharge holes) and the second refrigerant discharge holes.
