There is provided an alternating current generator for a vehicle, including: a rotor (), a flywheel (), and main magnets () and auxiliary magnets () alternately arranged; and a stator (). Each of the main magnets () is magnetized to an N-pole and an S-pole in a radial direction, whereas the main magnets () are arranged so that the main magnets () adjacent to each other through corresponding one of the auxiliary magnets () therebetween are magnetized to have opposite polarity patterns. Each of the auxiliary magnets () is magnetized to the N-pole and the S-pole in the circumferential direction, whereas the auxiliary magnets () are arranged so that the auxiliary magnets () adjacent to each other through corresponding one of the main magnets () therebetween are magnetized to have opposite polarity patterns.

Magnet-type rotating electric machine

A structure for efficiently transferring heat generated from an electronic part or the like to a heat dissipation member is provided. A bus bar is used for a wiring pattern in an electronic device (), such as a power line (), a GND line () and the like. A heat transfer member () is held between a first bus bar that is a power line () connected to an electronic part and a second bus bar that is a GND line () connected to a heat dissipation member () to configure a heat dissipation structure in which heat generated from the electronic part is transferred through the power line (), the heat transfer member () and the GND line () to the heat dissipation member ().
