Abstract

A coolant flow channel is formed so as to pass axially through a rotor core radially inside magnet housing apertures, a linking flow channel is formed so as to have a flow channel width that is narrower than a maximum flow channel width of the coolant flow channel, so as to link the coolant flow channel and the magnet housing apertures, and so as to pass axially through the rotor core, and permanent magnets are fixed to an inner wall surface of the magnet housing apertures by an adhesive that is disposed only between a wall surface of the permanent magnets that is positioned on a radially outer side and the inner wall surface of the magnet housing apertures so as to expose a region of a wall surface of the permanent magnets that is positioned on a radially inner side that faces the linking flow channel.
