Abstract
A vehicular alternator is provided which can suppress the vibration of a circuit board. The vehicular alternator has a rectifier that includes a plurality of diodes forming a full-wave rectifier circuit, a pair of negative and positive terminal side heat sinks that hold the diodes, and a circuit board connecting the diodes and a stator coil to one another, wherein the negative and positive terminal side heat sinks and the circuit board are mounted on a casing at a plurality of mounting portions, which are superposed with one another in an axial direction of a shaft, by using mounting members. Between adjacent ones of the mounting portions, there are formed abutment portions in which the circuit board is superposed on and placed in abutment with the negative terminal side heat sink or the positive terminal side heat sink, and the abutment portions are fixed to each other by rivets.
